Pull more clk updates from Stephen Boyd:
"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"

Pull clk updates from Stephen Boyd:
"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.
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"

There is minor difference between previous family of SoC and
the current one. Which is the there is only 48Mh fixed clk.
There is no mux and no option to select another freq as there in previous.

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"

Pull ARM SoC DT updates from Arnd Bergmann:
"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:

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.

The function __clk_get_flags has not been used since the April 2019
commit a348f05361c9 ("ARM: omap2+: hwmod: drop CLK_IS_BASIC

commit 98d8a60eccee ("clk: Convert __clk_get_flags() to

be used instead.

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.

is from an external 32.768kHz clock, and the other is from an
external 24MHz/48MHz main clock that is divided by 512. The
choice of these two clocks is controlled by the ERCS bit in
the OPCR register. The RNG unit will also use this clock.

Some of the SAMA7G5 PLLs support multiple outputs (e.g. AUDIO PLL).
For these, split the PLL clock in two: fractional clock and
divider clock. In case PLLs supports multiple outputs (since these
outputs are dividers (with different settings) sharing the same
fractional part), it will register one fractional clock and multiple
divider clocks (dividers sharing the fractional clock).

Pass the ID of changeable parent at registration. This will allow
the scalability of this clock driver with regards to the changeable
parent ID for versions of this IP where changeable parent is not the
last one in the parents list (e.g. SAMA7G5). With this the clock flags
are set to zero in case we have no changeable parent. Also in
clk_generated_best_diff() the *best_diff variable is check against
tmp_diff variable using ">=" operator instead of ">" so that in case
the requested frequency could be obtained using fix parents + gck
dividers but the clock also supports changeable parent to be able
to force the usage of the changeable parent.
