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"

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"

Add new API k3_ringacc_request_rings_pair() to request pair of rings at
once, as in the most cases Rings are used with DMA channels, which need to
request pair of rings - one to feed DMA with descriptors (TX/RX FDQ) and
one to receive completions (RX/TX CQ). This will allow to simplify Ringacc
API users.

Qualcomm driver updates for v5.9
For RPMh this fixes an issue where ktime was used during suspend, allows
the driver to be used on ARM targets and some minor cleanups.
It adds support for the latest format version in the socinfo driver and
adds identifiers for SM8250 and SDM630.
SMD-RPM gains compatibles for MSM8994 and MSM8936 and the Qualcomm SCM
gains compatibles MSM8994 and IPQ8074.
The GENI core code gains interconnect path voting and performance level
support, with subsequent patches integrating this with the SPI, I2C,
UART and QSPI drivers.
Following this the KGDB support for the GENI serial driver is improved,
the performance related to chip-select is improved for SPI and QSPI.

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.
