Linus Torvalds 30185b69a2 It looks like a smaller batch of clk updates this time around. In the core
framework we just have some minor tweaks and a debugfs feature, so not much to
 see there. The driver updates are fairly well split between AT91 and Qualcomm
 clk support. Adding those two drivers together equals about 50% of the
 diffstat. Otherwise, the big amount of work this time was on supporting
 Broadcom's Raspberry Pi firmware clks. See below for some more highlights.
 
 Core:
  - Document clk_hw_round_rate() so it gets some more use
  - Remove unused __clk_get_flags()
  - Add a prepare/enable debugfs feature similar to rate setting
 
 New Drivers:
  - Add support for SAMA7G5 SoC clks
  - Enable CPU clks on Qualcomm IPQ6018 SoCs
  - Enable CPU clks on Qualcomm MSM8996 SoCs
  - GPU clk support for Qualcomm SM8150 and SM8250 SoCs
  - Audio clks on Qualcomm SC7180 SoCs
  - Microchip Sparx5 DPLL clk
  - Add support for the new Renesas RZ/G2H (R8A774E1) SoC
 
 Updates:
  - Make defines for bcm63xx-gate clks to use in DT
  - Support BCM2711 SoC firmware clks
  - Add HDMI clks for BCM2711 SoCs
  - Add RTC related clks on Ingenic SoCs
  - Support USB PHY clks on Ingenic SoCs
  - Support gate clks on BCM6318 SoCs
  - RMU and DMAC/GPIO clock support for Actions Semi S500 SoCs
  - Use poll_timeout functions in Rockchip clk driver
  - Support Rockchip rk3288w SoC variant
  - Mark mac_lbtest critical on Rockchip rk3188
  - Add CAAM clock support for i.MX vf610 driver
  - Add MU root clock support for i.MX imx8mp driver
  - Amlogic g12: add neural network accelerator clock sources
  - Amlogic meson8: remove critical flag for main PLL divider
  - Amlogic meson8: add video decoder clock gates
  - Convert one more Renesas DT binding to json-schema
  - Enhance critical clock handling on Renesas platforms to only consider
    clocks that were enabled at boot time

Linus Torvalds 822ef14e9d ARM: SoC driver updates for v5.9
A couple of subsystems have their own subsystem maintainers but choose
 to have the code merged through the soc tree as upstream, as the code
 tends to be used across multiple SoCs or has SoC specific drivers itself:
 
  - memory controllers:
      Krzysztof Kozlowski takes ownership of the drivers/memory
      subsystem and its drivers, starting out with a set of cleanup
      patches.
      A larger driver for the Tegra memory controller that was accidentally
      missed for v5.8 is now added.
 
  - reset controllers:
      Only minor updates to drivers/reset this time
 
  - firmware:
      The "turris mox" firmware driver gains support for signed firmware blobs
      The tegra firmware driver gets extended to export some debug information
      Various updates to i.MX firmware drivers, mostly cosmetic
 
  - ARM SCMI/SCPI:
      A new mechanism for platform notifications is added, among a number
      of minor changes.
 
  - optee:
      Probing of the TEE bus is rewritten to better support detection of
      devices that depend on the tee-supplicant user space.
      A new firmware based trusted platform module (fTPM) driver is added
      based on OP-TEE
 
  - SoC attributes:
      A new driver is added to provide a generic soc_device for identifying
      a machine through the SMCCC ARCH_SOC_ID firmware interface rather than
      by probing SoC family specific registers.
      The series also contains some cleanups to the common soc_device code.
 
 There are also a number of updates to SoC specific drivers,
 the main ones are:
 
  - Mediatek cmdq driver gains a few in-kernel interfaces
 
  - Minor updates to Qualcomm RPMh, socinfo, rpm drivers, mostly adding
    support for additional SoC variants
 
  - The Qualcomm GENI core code gains interconnect path voting and
    performance level support, and integrating this into a number of
    device drivers.
 
  - A new driver for Samsung Exynos5800 voltage coupler for
 
  - Renesas RZ/G2H (R8A774E1) SoC support gets added to a couple of SoC
    specific device drivers
 
  - Updates to the TI K3 Ring Accelerator driver

 It adds IPQ6018 support to the SMD RPM driver, fixes kerneldoc in the
 same and converts the related DT binding to YAML.
 Finally it fixes a compilation warning in the geni serial engine driver
 when compiled without CONFIG_SERIAL_EARLYCON.

Marek Szyprowski 00067ca533 soc: samsung: exynos-regulator-coupler: Add simple voltage coupler for Exynos5800
Add a simple custom voltage regulator coupler for Exynos5800 SoCs, which
require coupling between "vdd_arm" and "vdd_int" regulators. This coupler
ensures that the voltage values don't go below the bootloader-selected
operation point during the boot process until the clients set their
constraints. It is achieved by assuming minimal voltage value equal to
the current value if no constraints are set. This also ensures proper
voltage balancing if any of the client driver is missing.

The balancing code comes from the regulator/core.c with the additional
logic for handling regulators without client constraints applied added.

Rajendra Nayak 4a3107f61f tty: serial: qcom-geni-serial: Drop the icc bw votes in suspend for console
When using the geni-serial as console, its important to be
able to hit the lowest possible power state in suspend,
even with no_console_suspend.
The only thing that prevents it today on platforms like the sc7180
is the interconnect BW votes, which we certainly don't need when
the system is in suspend. So in the suspend handler mark them as
ACTIVE_ONLY (0x3) and on resume switch them back to the ALWAYS tag (0x7)

structure but there are no users treewide. While trying to understand
the motivation and tried to use it, it was found lot of existing custom

Though most of these never remove/cleanup the custom attribute as they
never call soc_device_unregister, using these custom attribute group
eliminate the need for any cleanup as the driver infrastructure will
take care of that.

Let us remove device_create_file and start using the custom attribute

Herbert Xu 7999096fa9 iov_iter: Move unnecessary inclusion of crypto/hash.h
The header file linux/uio.h includes crypto/hash.h which pulls in
most of the Crypto API.  Since linux/uio.h is used throughout the
kernel this means that every tiny bit of change to the Crypto API
causes the entire kernel to get rebuilt.

This patch fixes this by moving it into lib/iov_iter.c instead
where it is actually used.

This patch also fixes the ifdef to use CRYPTO_HASH instead of just
CRYPTO which does not guarantee the existence of ahash.

Unfortunately a number of drivers were relying on linux/uio.h to
provide access to linux/slab.h.  This patch adds inclusions of
linux/slab.h as detected by build failures.

Also skbuff.h was relying on this to provide a declaration for
ahash_request.  This patch adds a forward declaration instead.

Linus Torvalds f7db192b2d ARM: OMAP fixes for v5.8
The OMAP developers are particularly active at hunting down regressions,
 so this is a separate branch with OMAP specific fixes for the v5.8:
 
 As Tony explains
  "The recent display subsystem (DSS) related platform data changes
   caused display related regressions for suspend and resume. Looks like
   I only tested suspend and resume before dropping the legacy platform
   data, and forgot to test it after dropping it. Turns out the main issue
   was that we no longer have platform code calling pm_runtime_suspend
   for DSS like we did for the legacy platform data case, and that fix
   is still being discussed on the dri-devel list and will get merged
   separately. The DSS related testing exposed a pile other other display
   related issues that also need fixing though":
 
  - Fix ti-sysc optional clock handling and reset status checks
    for devices that reset automatically in idle like DSS
 
  - Ignore ti-sysc clockactivity bit unless separately requested
    to avoid unexpected performance issues
 
  - Init ti-sysc framedonetv_irq to true and disable for am4
 
  - Avoid duplicate DSS reset for legacy mode with dts data
 
  - Remove LCD timings for am4 as they cause warnings now that we're
    using generic panels
 
 Other OMAP changes from Tony include:
 
  - Fix omap_prm reset deassert as we still have drivers setting the
    pm_runtime_irq_safe() flag
 
  - Flush posted write for ti-sysc enable and disable
 
  - Fix droid4 spi related errors with spi flags
 
  - Fix am335x USB range and a typo for softreset
 
  - Fix dra7 timer nodes for clocks for IPU and DSP
 
  - Drop duplicate mailboxes after mismerge for dra7
 
  - Prevent pocketgeagle header line signal from accidentally setting
    micro-SD write protection signal by removing the default mux
 
  - Fix NFSroot flakeyness after resume for duover by switching the
    smsc911x gpio interrupt to back to level sensitive
 
  - Fix regression for omap4 clockevent source after recent system
    timer changes
 
  - Yet another ethernet regression fix for the "rgmii" vs "rgmii-rxid"
    phy-mode
 
  - One patch to convert am3/am4 DT files to use the regular sdhci-omap
    driver instead of the old hsmmc driver, this was meant for the
    merge window but got lost in the process.

Arnd Bergmann 5b75f16f13 Fixes for omaps for v5.8
The recent display subsystem (DSS) related platform data changes caused
 display related regressions for suspend and resume. Looks like I only
 tested suspend and resume before dropping the legacy platform data, and
 forgot to test it after dropping it. Turns out the main issue was that
 we no longer have platform code calling pm_runtime_suspend for DSS like
 we did for the legacy platform data case, and that fix is still being
 discussed on the dri-devel list and will get merged separately. The DSS
 related testing exposed a pile other other display related issues that
 also need fixing though:
 
 - Fix ti-sysc optional clock handling and reset status checks
   for devices that reset automatically in idle like DSS
 
 - Ignore ti-sysc clockactivity bit unless separately requested
   to avoid unexpected performance issues
 
 - Init ti-sysc framedonetv_irq to true and disable for am4
 
 - Avoid duplicate DSS reset for legacy mode with dts data

Akash Asthana 048eb908a1 soc: qcom-geni-se: Add interconnect support to fix earlycon crash
QUP core clock is shared among all the SE drivers present on particular
QUP wrapper, the system will reset(unclocked access) if earlycon used after
QUP core clock is put to 0 from other SE drivers before real console comes
up.

As earlycon can't vote for it's QUP core need, to fix this add ICC
support to common/QUP wrapper driver and put vote for QUP core from
probe on behalf of earlycon and remove vote during earlycon exit call.

Douglas Anderson be24c6a71e soc: qcom: rpmh-rsc: Don't use ktime for timeout in write_tcs_reg_sync()
The write_tcs_reg_sync() may be called after timekeeping is suspended
so it's not OK to use ktime.  The readl_poll_timeout_atomic() macro
implicitly uses ktime.  This was causing a warning at suspend time.

Change to just loop 1000000 times with a delay of 1 us between loops.
This may give a timeout of more than 1 second but never less and is
safe even if timekeeping is suspended.

NOTE: I don't have any actual evidence that we need to loop here.
It's possibly that all we really need to do is just read the value
back to ensure that the pipes are cleaned and the looping/comparing is
totally not needed.  I never saw the loop being needed in my tests.
However, the loop shouldn't hurt.
