ARM: SoC driver updates for 4.17
The most noteworthy SoC driver changes this time include: - The TEE subsystem gains an in-kernel interface to access the TEE from device drivers. - The reset controller subsystem gains a driver for the Qualcomm Snapdragon 845 Power Domain Controller. - The Xilinx Zynq platform now has a firmware interface for its platform management unit. This contains a firmware "ioctl" interface that was a little controversial at first, but the version we merged solved that by not exposing arbitrary firmware calls to user space. - The Amlogic Meson platform gains a "canvas" driver that is used for video processing and shared between different high-level drivers. The rest is more of the usual, mostly related to SoC specific power management support and core drivers in drivers/soc: - Several Renesas SoCs (RZ/G1N, RZ/G2M, R-Car V3M, RZ/A2M) gain new features related to power and reset control. - The Mediatek mt8183 and mt6765 SoC platforms gain support for their respective power management chips. - A new driver for NXP i.MX8, which need a firmware interface for power management. - The SCPI firmware interface now contains support estimating power usage of performance states - The NVIDIA Tegra "pmc" driver gains a few new features, in particular a pinctrl interface for configuring the pads. - Lots of small changes for Qualcomm, in particular the "smem" device driver. - Some cleanups for the TI OMAP series related to their sysc controller. Additional cleanups and bugfixes in SoC specific drivers include the Meson, Keystone, NXP, AT91, Sunxi, Actions, and Tegra platforms.

Devicetree updates for 4.20:
- Sync dtc with upstream version v1.4.7-14-gc86da84d30e4 - Work to get rid of direct accesses to struct device_node name and type pointers in preparation for removing them. New helpers for parsing DT cpu nodes and conversions to use the helpers. printk conversions to %pOFn for printing DT node names. Most went thru subystem trees, so this is the remainder. - Fixes to DT child node lookups to actually be restricted to child nodes instead of treewide. - Refactoring of dtb targets out of arch code. This makes the support more uniform and enables building all dtbs on c6x, microblaze, and powerpc. - Various DT binding updates for Renesas r8a7744 SoC - Vendor prefixes for Facebook, OLPC - Restructuring of some ARM binding docs moving some peripheral bindings out of board/SoC binding files - New "secure-chosen" binding for secure world settings on ARM - Dual licensing of 2 DT IRQ binding headers -----BEGIN PGP SIGNATURE----- iQJEBAABCgAuFiEEktVUI4SxYhzZyEuo+vtdtY28YcMFAlvTKWYQHHJvYmhAa2Vy bmVsLm9yZwAKCRD6+121jbxhw8J5EACMAnrTxWQmXfQXOZEVxztcFavH6LP8mh2e 7FZIZ38jzHXXvl81tAg1nBhzFUU/qtvqW8NDCZ9OBxKvp6PFDNhWu241ZodSB1Kw MZWy2A9QC+qbHYCC+SB5gOT0+Py3v7LNCBa5/TxhbFd35THJM8X0FP7gmcCGX593 9Ml1rqawT4mK5XmCpczT0cXxyC4TgVtpfDWZH2KgJTR/kwXVQlOQOGZ8a1y/wrt7 8TLIe7Qy4SFRzjhwbSta1PUehyYfe4uTSsXIJ84kMvNMxinLXQtvd7t9TfsK8p/R WjYUneJskVjtxVrMQfdV4MxyFL1YEt2mYcr0PMKIWxMCgGDAZsHPoUZmjyh/PrCI uiZtEHn3fXpUZAV/xEHHNirJxYyQfHGiksAT+lPrUXYYLCcZ3ZmqiTEYhGoQAfH5 CQPMuxA6yXxp6bov6zJwZSTZtkXciju8aQRhUhlxIfHTqezmGYeql/bnWd+InNuR upANLZBh6D2jTWzDyobconkCCLlVkSqDoqOx725mMl6hIcdH9d2jVX7hwRf077VI 5i3CyPSJOkSOLSdB8bAPYfBoaDtH2bthxieUrkkSbIjbwHO1H6a2lxPeG/zah0a3 ePMGhi7J84UM4VpJEi000cP+bhPumJtJrG7zxP7ldXdfAF436sQ6KRptlcpLpj5i IwMhUQNH+g== =335v -----END PGP SIGNATURE----- Merge tag 'devicetree-for-4.20' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux Pull Devicetree updates from Rob Herring: "A bit bigger than normal as I've been busy this cycle.

This is the bulk of GPIO changes for the v4.20 series:
Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch. The irqchip callbacks have been improved so that they can use only the fastpatch callbacks to enable/disable irqs like any normal irqchip, especially the gpiod_lock_as_irq() has been improved to be callable in fastpath context. A bunch of rework had to be done to achieve this but it is a big win since I never liked to restrict this to slowpath. The only call requireing slowpath was try_module_get() and this is kept at the .request_resources() slowpath callback. In the GPIO CEC driver this is a big win sine a single line is used for both outgoing and incoming traffic, and this needs to use IRQs for incoming traffic while actively driving the line for outgoing traffic. - Janusz Krzysztofik improved the GPIO array API to pass a "cookie" (struct gpio_array) and a bitmap for setting or getting multiple GPIO lines at once. This improvement orginated in a specific need to speed up an OMAP1 driver and has led to a much better API and real performance gains when the state of the array can be used to bypass a lot of checks and code when we want things to go really fast. The previous code would minimize the number of calls down to the driver callbacks assuming the CPU speed was orders of magnitude faster than the I/O latency, but this assumption was wrong on several platforms: what we needed to do was to profile and improve the speed on the hot path of the array functions and this change is now completed. - Clean out the painful and hard to grasp BNF experiments from the device tree bindings. Future approaches are looking into using JSON schema for this purpose. (Rob Herring is floating a patch series.) New drivers: - The RCAR driver now supports r8a774a1 (RZ/G2M). - Synopsys GPIO via CREGs driver. Major improvements: - Modernization of the EP93xx driver to use irqdomain and other contemporary concepts. - The ingenic driver has been merged into the Ingenic pin control driver and removed from the GPIO subsystem. - Debounce support in the ftgpio010 driver. -----BEGIN PGP SIGNATURE----- iQIcBAABAgAGBQJbzdyOAAoJEEEQszewGV1zfYcP/0HBEAOPhHD/i5OQxfKs1msh mFT/t/IbTmRpCgbEv4CDx4Kc/InE0sUnQr1TL/1WvU6uObM6Ncxq5Z90MvyrgzYu BqQHq2k2tORvkVSNRxcfD/BAAoo1EerXts1kDhutvdKfepfS6DxpENwzvsFgkVlq 2jj1cdZztjv8A+9cspHDpQP+jDvl1VSc10nR5fRu1TttSpUwzRJaB30NBNXJmMJc 5KUr67lEbsQRPsBvFErU11bydPqhfT+pXmODcfIwS0EtATQ8WC5mkSb/Ooei0fvT oZ7uR3Os8tMf7isOKssEyFabKwhnfOEt6TBt9em0TfUtInOo0Dc7r8TfBcn57fyZ xg2R9DQEVRfac8bjhF/BI5KHuN9IMGDDvj6XApumQVliZbISRjMnh3jte6RpcV0A Ejqz8FeDY13qvEdOnW1EPpwmXdDVWiEAq0ebGLStKNls+/4gB2HmyxGUOzJf+og5 hujsxcJzGQqjCe0moeY/1d7vsy0ZjbHoS+p5fy79U212y2O7onEzFU92AX89bxKC rx2eCNmiZxCUy1nqu8edO62VnH6QdnqG3o+a4DJfCSHPvFM/E/NX9zHemZubQQ4I rYXNy4bL4tEG9cqWMfBxWrpiDZw7H6l8kXwdZG8IMyRU9BcKu96amgZ+jBXwzoaB JZelAAUWB9APghJYFr7o =YosT -----END PGP SIGNATURE----- Merge tag 'gpio-v4.20-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-gpio Pull GPIO updates from Linus Walleij: "This is the bulk of GPIO changes for the v4.20 series: Core changes: - A patch series from Hans Verkuil to make it possible to enable/disable IRQs on a GPIO line at runtime and drive GPIO lines as output without having to put/get them from scratch.

TI sysc driver changes for v4.20 merge window
This series gets rid of the SYSC_QUIRK_RESOURCE_PROVIDER to make device detection happen mostly only if #define DEBUG is set. Few core devices still need to be detected to set legacy quirks. We also add support for booting am335x, am437x and dra7 SoCs with L4 devices defined in device tree instead of legacy platform data. And finally we simplify suspend with just SET_NOIRQ_SYSTEM_SLEEP_PM_OPS and dropping the custom functions that were attempting to work around issues that really turned out to be child device driver related issues. Apologies for a late pull request, debugging the suspend issues took a while and I did not want to send these changes until that got sorted out. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAlu1AGARHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXMSuBAAvHJ6gKO2bv8AONDj6r1TBSoSjB7BwunL lnkDVKAzj/cNtahfqDuNLwFH0ftaQ21sS34qhFvvR3UVPBR+6BDz/NtUByh33ylh jvm3ZJ6AjscuOr9JH78yWQ08Xpqrbf02G4H3yzvFJMjIS9jA4HpEDDg6WKvGJMe7 aGFOFQP1DGrQbr+i6suCPY8wt2O/KOCV1euedJEql6Rt438d4uCygYxyV0aQJr6J kjM0T7Im8+3Y5RHkcCGP5sHAKVijBiduhzPgBTWYgpVGXc5Fo0aZMD7MdFwAZNlB 2cwX3cEhpDtbB9lnf7/N9zPrpnUrzreN/b1Xq9Dp8nvWdhudBRQsuuMccMgtU+IR e6s2EbEXSx/H8aVd2YH0ZJF1hA92AVOoesUHZ7NlmyDW4WkbGijy3YdzSiRfohBD AJ2INcmgSE0jhKKaB77+oWt5ey3Me+UIkArCKaNT/4BtNzDk6UrwkmLU4nFjjx2g eSvtih97oSHX59L6kQb0SINHuKRNc5i05bq2lIKt6RDiDxwa5FD2UaqojApTFRL9 KOCfOjRAc+22SY0PP4CUVoEUvD2xibrjKci3Uho5/vgeHTA9tE9c8Gw3OyNXj7Tg z7JTvwy49gV3qqAU6iEmFB5uvBXyKMe6nB7f2DyJ7IgRYcjwkoy15b5tcRBpT9SM N2iAVnfn23k= =f9xh -----END PGP SIGNATURE----- Merge tag 'omap-for-v4.20/ti-sysc-take2-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/drivers TI sysc driver changes for v4.20 merge window This series gets rid of the SYSC_QUIRK_RESOURCE_PROVIDER to make device detection happen mostly only if #define DEBUG is set.

bus: ti-sysc: Just use SET_NOIRQ_SYSTEM_SLEEP_PM_OPS

Let's also remove the PM_SLEEP ifdef and use __maybe_unused as the PM code already deals with the ifdefs.

We don't care when we suspend but some our children do. In order to avoid tagging various modules with SYSC_QUIRK_RESOURCE_PROVIDER, let's do it automatically by tagging modules that are busy on suspend for noirq suspend. This way we can just do module detection on define DEBUG. Note that we still need to keep SYSC_QUIRK_LEGACY_IDLE flag around so the our legacy single-child devices that set pm_runtime_irq_safe() can manage the interconnect target module themselves.

gpiolib: Pass bitmaps, not integer arrays, to get/set array
Most users of get/set array functions iterate consecutive bits of data, usually a single integer, while processing array of results obtained from, or building an array of values to be passed to those functions. Save time wasted on those iterations by changing the functions' API to accept bitmaps. All current users are updated as well. More benefits from the change are expected as soon as planned support for accepting/passing those bitmaps directly from/to respective GPIO chip callbacks if applicable is implemented.

bus: ti-sysc: Fix module register ioremap for larger offsets
We can have the interconnect target module control registers pretty
much anywhere within the module range. The current code attempts an
incomplete optimization of the ioremap size but does it wrong and
it only works for registers at the beginning of the module.
Let's just use the largest control register to calculate the ioremap
size. The ioremapped range is for most part cached anyways so there
is no need for size optimization. Let's also update the comments
accordingly.

treewide: devm_kzalloc() -> devm_kcalloc()
The devm_kzalloc() function has a 2-factor argument form, devm_kcalloc(). This patch replaces cases of: devm_kzalloc(handle, a * b, gfp) with: devm_kcalloc(handle, a * b, gfp) as well as handling cases of: devm_kzalloc(handle, a * b * c, gfp) with: devm_kzalloc(handle, array3_size(a, b, c), gfp) as it's slightly less ugly than: devm_kcalloc(handle, array_size(a, b), c, gfp) This does, however, attempt to ignore constant size factors like: devm_kzalloc(handle, 4 * 1024, gfp) though any constants defined via macros get caught up in the conversion. Any factors with a sizeof() of "unsigned char", "char", and "u8" were dropped, since they're redundant. Some manual whitespace fixes were needed in this patch, as Coccinelle really liked to write "=devm_kcalloc..." instead of "= devm_kcalloc...". The Coccinelle script used for this was: // Fix redundant parens around sizeof(). @@ expression HANDLE; type TYPE; expression THING, E; @@ ( devm_kzalloc(HANDLE, - (sizeof(TYPE)) * E + sizeof(TYPE) * E , ...) | devm_kzalloc(HANDLE, - (sizeof(THING)) * E + sizeof(THING) * E , ...) ) // Drop single-byte sizes and redundant parens. @@ expression HANDLE;

ARM: SoC platform updates
Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms. The branch also contains defconfig updates to turn on drivers and options as needed on the various platforms. The largest parts of the delta are from cleanups moving platform data and board file setup of TI platforms to ti-sysc bus drivers. There are also some sweeping changes of eeprom and nand setup on Davinci, i.MX and other platforms. Samsung is removing support for Exynos5440, which was an oddball SoC that hasn't been seen much use in designs. Renesas is adding support for new SoCs (R-Car E3, RZ/G1C and RZ/N1D). Linus Walleij is also removing support for ux500 (Sony Ericsson) U8540/9540 SoCs that never made it to significant mass production and products. -----BEGIN PGP SIGNATURE----- iQJDBAABCAAtFiEElf+HevZ4QCAJmMQ+jBrnPN6EHHcFAlsfCGIPHG9sb2ZAbGl4 b20ubmV0AAoJEIwa5zzehBx3Ks8P/3j87Za+6OTCzo+lW2byUy1CI4muGwxNSIxX 65A1Wt2qvRDxjCX4MI5Cx8P1YdYJv+5ZF2p4vdlgQXoz3/XDbG+lxJ+/lyWl/+MK 9kGsQWwEVicbGkaJCYR4ZKvfAwZ9jf7+cndY0Vgii44xQLsQZHEIfIO+mdlK43GZ xqaSckLQQzsDqjMUIckiyVy97RsDk1eLK+H2I+l7qs9v0z5UnhoD2CTxX5LzT8eH NlFmfUPN7Znshmt0aMznZyBRr2oM5Dsg49SfG0WhbOzyiZjSpw8MQ0N+RzyROhhB h5PjyuZN9fx2dO8Jjkqt3B8KmGFNDarGOmrasIJeCJDFRa9NStqFn0y4qJXS2wU7 4La3GoBYRV8x0gq339pQ+70qKuD06e62GL7kV656yi+93CitWxy6IjrIACjSX6zH PD1hQpewfXAcHAHdBqNevRcz/sjG+36GJSCgI4umSP48NMlCuZafFAT4U/PVlt4E 6VRQDeoi5ZFYIuPL1+bZvHax4fFxJGnaf02uQ/OPYP1o48AueSSvdo6bUPFbhwOD u0/uo3r+HxtQsw9I3tP3kj3/775BJclkO6zbG/dGZ8obuzuDwhuFtr3rzCrP/IzN n3rcBuFNZE6SQeKU+Tvmnh8ZLhJc5L8EYvqmihZj+BSfprBc8POFR2la4MRnHSn+ tPEC/n9E =S5wc -----END PGP SIGNATURE----- Merge tag 'armsoc-soc' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM SoC platform updates from Olof Johansson: "Here are the main updates for SoC support (besides DT additions) for ARM 32- and 64-bit platforms.

ti-sysc driver related changes for omap variants
This series improves the ti-sysc interconnect target module driver to the point where a most of SoC can be booted with interconnect target module data configured in device tree instead of legacy platform data. The related device tree changes need some more work though, and can wait for v4.19. Also some drivers using nested interconnects like DSS need more work. We can now remove the unused pm-noop code that is not doing anything any longer. And we can now initialize things for PM and display pdata later to prepare things for using ti-sysc driver. We also need to add some more quirk handling so we can boot both with platform data and dts data. -----BEGIN PGP SIGNATURE----- iQJFBAABCAAvFiEEkgNvrZJU/QSQYIcQG9Q+yVyrpXMFAlrsg9QRHHRvbnlAYXRv bWlkZS5jb20ACgkQG9Q+yVyrpXNmwxAAzPt1GpHQSw/XhhtK8+DLlqo9fdPQ9C65 Iw+PyvQYy2bTj0y64VkZ4Msmi3SOhfr5zKhIrwBHEG59/LW81oXqnb9JZHPP+YC+ /A6ZufXIt8X+Nd1L6id2OD9ItJoLXk7llBvDckwb/zUgcVib9cA79GvWgexfRWBE w/bjZfUibddYdhKoCGmvWcZBapDKHMfv8MdN8h0QUyofTIefZZeykRvb1Pmn7Ntl vz3QfPUq3oyRfG9PMRI7mjHrW7jxEKgjvWANbUg64UQJN7s1tfa8ICpzycc4/X/a pdetH7G+BPaRdeqDCmGrcGHfO4b5HyD7nkTD3R6yzV+Dw8nWl+aWGJHAsPYRUJkd o/BroflhqK2ICfEkeK6AWebbicOSlF5P+EEFwp6pHSd/9JiEqR1IkhcCvTdV8CB1 qyUQxD+iKof+rY5f1EicaGq8HXhkV+9aIOoqBH6C0qObEJDUWvVoGIzDdN2vwVAu C2w9WqdQII3R4g2ZX1SmdEqFO/f6PkAoKiyNt+WGBGBUfYo1sfwpkFAEeGU50moJ 5m9TtLcAbbvgMwy2ttfWcHPn5z3p4Ocf7aN93TZ6RPk6A6R57PzCcYqJ2bXsumeV 5yaP9w4pbFj+FQuu8jA8s/cSwhIP8SwqwFWKCi2JcU3ugEdJfwF555y5bm0R9MDz 7W82aAicw+M= =jYZ6 -----END PGP SIGNATURE----- Merge tag 'omap-for-v4.18/ti-sysc-signed' of git://git.kernel.org/pub/scm/linux/kernel/git/tmlind/linux-omap into next/soc ti-sysc driver related changes for omap variants This series improves the ti-sysc interconnect target module driver to the point where a most of SoC can be booted with interconnect target module data configured in device tree instead of legacy platform data.

genirq/msi: Limit level-triggered MSI to platform devices
Nobody would be insane enough to try and use level triggered MSIs on PCI, but let's make sure it doesn't happen. Also, let's mandate that the irqchip backing the platform MSI domain is providing the IRQCHIP_SUPPORTS_LEVEL_MSI flag.

HISI LPC: Add ACPI UART support
On the Huawei D03 development board the system UART is the UART connected on the LPC bus. The profile for the device driver required for this HW is as follows: - platform driver - 16550 - ACPI support - polling mode support - IO space support In principle we should use the PNP driver (8250_dw.c) for 8250-devices with ACPI FW. However since this driver does not support PNP devices, and modifying the PNP core code to support it is not worth the effort, use the generic 8250 isa driver. For this, we setup the pdev platform data for the serial 8250 port.

HISI LPC: Re-Add ACPI child enumeration support
Since we no longer use the MFD APIs to enumerate the child devices on the bus, use the platform driver APIs directly. In this patch we iterate of the children devices for the host, and create a platform device directly per child. For the iterating, we match the child ACPI HID against a known list of supported child devices and their respective ACPIs HID, to find the device name and any other supplementary data.

HISI LPC: Stop using MFD APIs
The MFD APIs should only be used by drivers in drivers/mfd. It is not worth splitting the driver to have separate parts in drivers/bus and drivers/mfd, so just drop MFD API usage. As a solution, we will use the platform device APIs directly to achieve the same as we had when using MFD APIs.
