Linus Torvalds fded091988 pwm: Changes for v5.9-rc1
The majority of this batch is conversion of the PWM period and duty
 cycle to 64-bit unsigned integers, which is required so that some types
 of hardware can generate the full range of signals that they're capable
 of. The remainder is mostly minor fixes and cleanups.

Linus Torvalds 05a5b5d8a2 Here's some more updates that missed the last pull request because I
happened to tag the tree at an earlier point in the history of clk-next.
 I must have fat fingered it and checked out an older version of clk-next
 on this second computer I'm using.
 
 This time it actually includes more code for Qualcomm SoCs, the AT91
 major updates, and some Rockchip SoC clk driver updates as well. I've
 corrected this flow so this shouldn't happen again.

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

Merge tag 'arm-drivers-5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "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"

Linus Torvalds 2f3fbfdaf7 ARM: SoC DT changes for 5.9
As usual, there are many patches addressing minor issues in existing
 DTS files, such as DTC warnings, or adding support for additional
 peripherals.
 
 There are three added SoCs in existing product families:
 
  - Amazon:
     Alpine v3 is a 16-core Cortex-A72 SoC from Amazon's Annapurna Labs,
     otherwise known as AL73400 or first-generation Graviton, and following
     the already supported Cortex-A1`5 and Cortex-A57 based Alpine chips.
     This one is added together with the official Evaluation platform.
 
  - Qualcomm:
     The Snapdragon SDM630 platform is a family of mid-range mobile phone
     chips from 2017 based on Cortex-A53 or Kryo 260 CPUs.
     A total of five end-user products are added based on these, all
     Android phones from Sony: Xperia 10, 10 Plus, XA2, XA2 Plus and
     XA2 Ultra.
 
  - Renesas:
     RZ/G2H (r8a774e1) is currently the top model in the Renesas RZ/G
     family, and apparently closely related to the RZ/G2N and RZ/G2M
     models we already support but has a faster GPU and additional
     on-chip peripherals.
     It is added along with the HopeRun HiHope RZ/G2H development board
 
 A small number of new boards for already supported SoCs also debut:
 
  - Allwinner sunxi:
     Only one new machine, revision v1.2 of the Pine64 PinePhone
     (non-Android) smartphone, containing minor changes compared to
     earlier versions.
 
  - Amlogic Meson:
     WeTek Core2 is an Amlogic S912 (GXM) based Set-top-box
 
  - Aspeed:
     EthanolX is AMD's EPYC data center rerence platform, using an
     ASpeed AST2600 baseboard management controller.
 
  - Mediatek:
     Lenovo IdeaPad Duet 10.1" (kukui/krane) is a new Chromebook
     based on the MT8183 (Helio P60t) SoC.
 
  - Nvidia Tegra:
     ASUS Google Nexus 7 and Acer Iconia Tab A500 are two Android
     tablets from around 2012 using Tegra 3 and Tegra 2, respectively.
     Thanks to PostmarketOS, these can now run mainline kernels
     and become useful again.
 
     The Jetson Xavier NX Developer Kit uses a SoM and carrier board
     for the Tegra194, their latest 64-bit chip based on Carmel CPU
     cores and Volta graphics.
 
  - NXP i.MX:
     Five new boards based on the 32-bit i.MX6 series are added:
     The MYiR MYS-6ULX single-board computer, and four different
     models of industrial computers from Protonic.
 
  - Qualcomm:
     MikroTik RouterBoard 3011 is a rackmounted router based on the
     32-bit IPQ8064 networking SoC
     Three older phones get added, the Snapdragon 808 (msm8992) based
     Xiaomi Libra (Mi 4C) and Microsoft Lumia 950, originally running
     Windows Phone, and the Snapdragon 810 (msm8994) based Sony
     Xperia Z5.
 
  - Renesas:
     In addition to the HiHope RZ/G2H board mentioned above, we gain
     support for board versions 3.0 and 4.0 of the earlier RZ/G2M and
     RZ/G2N reference boards.
     Beacon EmbeddedWorks adds another SoM+Carrier development board
     for RZ/G2M.
 
  - Rockchips:
     Radxa Rock Pi N8 development board and the VMARC RK3288 SoM it
     is based on, using the high-end 32-bit rk3288 SoC.
 
 Notable updates to existing platforms are usually for added on-chip
 peripherals, including:
 
  - ASpeed AST2xxx (various)
 
  - Allwinner (cpufreq, thermal, Pinephone touchscreen)
 
  - Amlogic Meson (audio, gpu dvdfs, board updates)
 
  - Arm Versatile
 
  - Broadcom (board updates for switch ports, Raspberry pi clock updates)
 
  - Hisilicon (various)
 
  - Intel/Altera SoCFPGA (various)
 
  - Marvell Armada 7xxx/8xxx (smmu)
 
  - Marvell MMP (GPU on mmp2/mmp3)
 
  - Mediatek mt8183 (USB, pericfg)
 
  - NXP Layerscape (VPU, thermal, DSPI)
 
  - NXP i.MX (VPU, bindings, board updates)
 
  - Nvidia Tegra194 (GPU)
 
  - Qualcomm (GPU, Interconnect, ...)
 
  - Renesas R-Car (SPI, IPMMU, board updates)

Nicolas Saenz Julienne f34e4651ce clk: bcm2835: Do not use prediv with bcm2711's PLLs
Contrary to previous SoCs, bcm2711 doesn't have a prescaler in the PLL
feedback loop. Bypass it by zeroing fb_prediv_mask when running on
bcm2711.

Note that, since the prediv configuration bits were re-purposed, this
was triggering miscalculations on all clocks hanging from the VPU clock,
notably the aux UART, making its output unintelligible.

Dmitry Osipenko fa64023763 clk: tegra: pll: Improve PLLM enable-state detection
Power Management Controller (PMC) can override the PLLM clock settings,
including the enable-state. Although PMC could only act as a second level
gate, meaning that PLLM needs to be enabled by the Clock and Reset
Controller (CaR) anyways if we want it to be enabled. Hence, when PLLM is
overridden by PMC, it needs to be enabled by CaR and ungated by PMC in
order to be functional. Please note that this patch doesn't fix any known
problem, and thus, it's merely a minor improvement.

Claudiu Beznea 35d06f7478 clk: at91: sam9x60-pll: use frac when setting frequency
In commit a436c2a447 ("clk: at91: add sam9x60 PLL driver")
the fractional part of PLL wasn't set on registers but it was
calculated and taken into account for determining div and mul
(see sam9x60_pll_get_best_div_mul()).

Claudiu Beznea 390227dca8 clk: at91: sam9x60-pll: check fcore against ranges
According to datasheet the range of 600-1200MHz is for the
frequency generated by the fractional part of the PLL (namely
Fcorepllck according to datasheet). With this in mind the output
range of the PLL itself (fractional + div), taking into account
that the divider is 8 bits wide, is 600/256-1200Hz=2.3-1200MHz.
