Linus Torvalds 991688bfc6 ARM: SoC driver updates for v4.10
Driver updates for ARM SoCs, including a couple of newly added drivers:
 
 - A new driver for the power management controller on TI Keystone
 - Support for the prerelease "SCPI" firmware protocol that ended up
   being shipped by Amlogic in their GXBB SoC.
 - A soc_device can now be matched using a glob from inside the
   kernel, when another driver wants to know the specific chip
   it is running on and cannot find out from DT, firmware or hardware.
 - Renesas SoCs now support identification through the soc_device
   interface, both in user space and kernel.
 - Renesas r8a7743 and r8a7745 gain support for their system controller
 - A new checking module for the ARM "PSCI" (not to be confused
   with "SCPI" mentioned above) firmware interface.
 - A new driver for the Tegra GMI memory interface
 - Support for the Tegra firmware interfaces with their
   power management controllers
 
 As usual, the updates for the reset controller framework are merged
 here, as they tend to touch multiple SoCs as well, including a new
 driver for the Oxford (now Broadcom) OX820 chip and the Tegra
 bpmp interface.
 
 The existing drivers for Atmel, Qualcomm, NVIDIA, TI Davinci, and
 Rockchips SoCs see some further updates.
 
 Conflicts:
 - ARCH_RENESAS now selects SOC_BUS, but no longer needs GPIOLIB
 - drivers/soc/renesas/Makefile: multiple files got added, keep
   all in logical sorting

Linus Torvalds 3bd776bbda ARM: SoC 64-bit changes for v4.9
Changes to platform code for 64-bit ARM platforms. We are not adding
 any new platforms that require code or Kconfig changes this time, so
 it's basically just defconfig changes to enable support for more
 drivers used on the existing platforms.
 
 This is mainly interesting for the Raspberry Pi 3, which should
 now work much better with the default build.

Identify the SoC type and revision, and register this information with
the SoC bus, so it is available under /sys/devices/soc0/, and can be
checked where needed using soc_device_match().

Identification is done using the Product Register or Common Chip Code
Register, as declared in DT (PRR only for now), or using a hardcoded
fallback if missing.

Michael Scott e19811a89d arm64: qcom: enable GPIOLIB in Kconfig
While debugging a kernel image size issue, I discovered that if all
non ARCH_QCOM configs in the ARM64 defconfig are disabled, the QCOM
pinctrl drivers will not be built.

The QCOM pinctrl drivers have a dependency on GPIOLIB which was being
selected when other ARCH configs were enabled, but ARCH_QCOM doesn't
select GPIOLIB directly.  Let's select GPIOLIB here to ensure the pinctrl
drivers are built for QCOM platforms.

Linus Torvalds a439f8f287 ARM: 64-bit DT updates for v4.8
The 64-bit DT changes are surprisingly small this time, we only add two
 SoC platforms: the ZTE ZX296718 Set-top-box SoC and the SocioNext
 UniPhier LD11 TV SoC, each with their reference boards.
 
 There are three new machines added for existing SoC platforms:
 
 - The Marvell Armada 8040 development board is an impressive quad-core
   Cortex-A72 machine with three 10gbit ethernet interfaces
 
 - Qualcomms DragonBoard 820c single-board computer is their current
   high-end phone platform in the 96boards form factor
 
 - Rockchip: Tronsmart Orion r86 set-top-box is a popular mid-range
   Android box based on the 8-core rk3368 SoC.

 both of which already have 32-bit support in arch/arm:
 
 - Broadcom adds abstract support for the bcm7xxx/brcmstb platform,
   presumably the respective dts files and more information will
   follow at a later point.
 
 - The ZTE ZX296718 SoC for set-top-boxes, a relative of the 32-bit
   ZX296702 SoC that we already support.

Linus Torvalds 6a497e9d58 This is the bulk of GPIO changes for the v4.9 series:
Subsystem improvements:
 
 - Do away with the last users of the obsolete Kconfig options
   ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
   always sounded like an item on a wishlist to Santa Claus to
   me). We can now select GPIOLIB and be done with it, for all
   archs. After some struggle it even work on UM. Not that it has
   GPIO, but if it wants to, it can select the library.
 
 - Continued efforts to make drivers properly either tristate or
   bool.
 
 - Introduce a warning for drivers assigning default triggers to
   their irqchip lines when probed from device tree, so we find and
   fix these ambigous drivers. It is agreed that in the OF config
   path, the device tree defines trigger characteristics.
 
 - The same warning, mutatis mutandis, for ACPI-probed GPIO
   irqchips.
 
 - We introduce the ability to mark certain IRQ lines as "unusable"
   as they can be taken by BIOS/firmware, unrouted in silicon and
   generally nasty if you use them, and such things. This is
   put to good use in the STMPE driver and also in the Cherryview
   pin control driver.
 
 - A new "mockup" virtual GPIO device that can be used for testing.
   The plan is to add unit tests under tools/* for exercising this
   device and verify that the kernel code paths are working as they
   should.
 
 - Make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
   implicit all the time, but when people started building UM
   with allyesconfig or allmodconfig it exploded in their face.
 
 - Move some stray bits of device tree and ACPI HW description
   callbacks down into their respective implementation silo. These
   were causing issues when compiling on !HAS_IOMEM as well, so
   now eventually UM compiles the GPIOLIB library if it wants to.
 
 New drivers:
 
 - New driver for the Aspeed GPIO front-end companion to the
   pin controller merged through the pin control tree.
 
 - New driver for the LP873x PMIC GPIO portions.
 
 - New driver for Technologic Systems' I2C FPGA GPIO such as
   TS4900, TS-7970, TS-7990 and TS-4100.
 
 - New driver for the Broadcom BCM63xx series including BCM6338
   and BCM6345.
 
 - New driver for the Intel WhiskeyCove PMIC GPIO.
 
 - New driver for the Allwinner AXP209 PMIC GPIO portions.
 
 - New driver for Diamond Systems 48 line GPIO-MM, another of
   these port-mapped I/O expansion cards.
 
 - Support the STMicroelectronics STMPE1600 variant in the STMPE
   driver.
 
 Driver improvements:
 
 - The STMPE driver now supports rising/falling edge detection
   properly for IRQs.
 
 - The PCA954x will now fetch and enable its VCC regulator properly.
 
 - Major rework of the PCA953x driver with the goal of eventually
   switching it over to use regmap and thus modernize it even more.
 
 - Switch the IOP driver to use the generic MMIO GPIO library.
 
 - Move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
   over to this subsystem from MFD, achieveing some separation of
   concerns.

Merge tag 'gpio-v4.9-1' 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 v4.9 series:

  Subsystem improvements:

   - do away with the last users of the obsolete Kconfig options
     ARCH_REQUIRE_GPIOLIB and ARCH_WANT_OPTIONAL_GPIOLIB (the latter
     always sounded like an item on a wishlist to Santa Claus to me). We
     can now select GPIOLIB and be done with it, for all archs. After
     some struggle it even work on UM. Not that it has GPIO, but if it
     wants to, it can select the library.

   - continued efforts to make drivers properly either tristate or bool.

   - introduce a warning for drivers assigning default triggers to their
     irqchip lines when probed from device tree, so we find and fix
     these ambigous drivers. It is agreed that in the OF config path,
     the device tree defines trigger characteristics.

   - the same warning, mutatis mutandis, for ACPI-probed GPIO irqchips.

   - we introduce the ability to mark certain IRQ lines as "unusable" as
     they can be taken by BIOS/firmware, unrouted in silicon and
     generally nasty if you use them, and such things. This is put to
     good use in the STMPE driver and also in the Cherryview pin control
     driver.

   - a new "mockup" virtual GPIO device that can be used for testing.
     The plan is to add unit tests under tools/* for exercising this
     device and verify that the kernel code paths are working as they
     should.

   - make memory-mapped I/O-drivers depend on HAS_IOMEM. This was
     implicit all the time, but when people started building UM with
     allyesconfig or allmodconfig it exploded in their face.

   - move some stray bits of device tree and ACPI HW description
     callbacks down into their respective implementation silo. These
     were causing issues when compiling on !HAS_IOMEM as well, so now
     eventually UM compiles the GPIOLIB library if it wants to.

  New drivers:

   - new driver for the Aspeed GPIO front-end companion to the pin
     controller merged through the pin control tree.

   - new driver for the LP873x PMIC GPIO portions.

   - new driver for Technologic Systems' I2C FPGA GPIO such as TS4900,
     TS-7970, TS-7990 and TS-4100.

   - new driver for the Broadcom BCM63xx series including BCM6338 and
     BCM6345.

   - new driver for the Intel WhiskeyCove PMIC GPIO.

   - new driver for the Allwinner AXP209 PMIC GPIO portions.

   - new driver for Diamond Systems 48 line GPIO-MM, another of these
     port-mapped I/O expansion cards.

   - support the STMicroelectronics STMPE1600 variant in the STMPE
     driver.

  Driver improvements:

   - the STMPE driver now supports rising/falling edge detection
     properly for IRQs.

   - the PCA954x will now fetch and enable its VCC regulator properly.

   - major rework of the PCA953x driver with the goal of eventually
     switching it over to use regmap and thus modernize it even more.

   - switch the IOP driver to use the generic MMIO GPIO library.

   - move the ages old HTC EGPIO (extended GPIO) GPIO expander driver
     over to this subsystem from MFD, achieveing some separation of
     concerns"

Pull irq updates from Thomas Gleixner:
 "The irq departement proudly presents:

   - A rework of the core infrastructure to optimally spread interrupt
     for multiqueue devices. The first version was a bit naive and
     failed to take thread siblings and other details into account.
     Developed in cooperation with Christoph and Keith.

   - Proper delegation of softirqs to ksoftirqd, so if ksoftirqd is
     active then no further softirq processsing on interrupt return
     happens. Otherwise we try to delegate and still run another batch
     of network packets in the irq return path, which then tries to
     delegate to ksoftirqd .....

   - A proper machine parseable sysfs based alternative for
     /proc/interrupts.

   - ACPI support for the GICV3-ITS and ARM interrupt remapping

   - Two new irq chips from the ARM SoC zoo: STM32-EXTI and MVEBU-PIC

   - A new irq chip for the JCore (SuperH)

   - The usual pile of small fixlets in core and irqchip drivers"

Merge tag 'tegra-for-4.9-arm64-dt' of git://git.kernel.org/pub/scm/linux/kernel/git/tegra/linux into next/dt64

Pull "arm64: tegra: Device tree changes for v4.9-rc1" from Thierry Reding:

Add a couple of devices (AGIC, ADMA) on Tegra210 and enable them on
Smaug. Also enable DPAUX on Smaug to allow the I2C bus that shares pads
with the DPAUX to be used to access various audio devices. Furthermore,
enable the XUSB controller on Smaug for USB 3.0 support.

Finally, select PM_GENERIC_DOMAINS for 64-bit Tegra devices to make sure
devices are probed only after their power partitions have been enabled.

Andre Przywara d229d20513 arm64: sunxi: Kconfig: add essential pinctrl driver
The pinctrl driver is essential for the Allwinner SoCs to work.
Add the driver's config symbol to the Kconfig entry to always compile
it in. We can't use the arm approach to make the _driver's_ Kconfig
symbol def_bool, because we lack the MACH_* symbols in arm64.
That line was in the original pinctrl driver patch, but got removed
to avoid the dependency on the Kconfig patch [1].
Also add the general PINCTRL symbol, which isn't selected automatically
for the same reason.

Sudeep Holla 8da7cc087b arm64: Kconfig: select PM{,_GENERIC_DOMAINS} for ARCH_VEXPRESS
The Linux AMBA bus framework probes the peripheral IDs when adding the
AMBA devices very early on the boot. Generally they are on APB bus and
just require APB clocks to be on even when most of the core logic of the
IP is powered down.

However on Juno, the entire debugsys domain needs to be ON to access
even the coresight components' CID/PID registers and hence broken by
design. Accessing those while debugsys power domain is off will lead to
the bridge stalling the transactions instead of returning the slave error.

Further, the AMBA framework can't deal with !CONFIG_PM_GENERIC_DOMAINS
case: it ignores the error and proceeds to access the device region.
It was suggested to always enable CONFIG_PM{,_GENERIC_DOMAINS} in order
to handle above explained scenario.

Krzysztof Kozlowski 3b3428e384 arm64: exynos: Select SOC specific drivers
Recently some Exynos drivers were moved from arm/mach-exynos to
drivers/soc. Building the directory depends on SOC_SAMSUNG Kconfig
option so we want it also on ARMv8 platforms, even though none of the
drivers support ARMv8 SoCs yet.

Linus Torvalds 9f8f202278 ARM: SoC 64-bit changes for v4.7
One new platform gets added this time: The Cortex-A53 based LG Electronics
 LG1K platform used in digital TVs.
 
 The other changes are mostly smaller updates to the defconfig files, to
 enable additional platform specific drivers, as they get merged through
 the subsystem trees.
