While the auxiliary bus was a nice bandaid, and meant that re-writing
the representation of the clock regions in devicetree was not required,
it has run its course. The "mss_top_sysreg" region that contains the
clock and reset regions, also contains pinctrl and an interrupt
controller, so the time has come rewrite the devicetree and probe the
reset controller from an mfd devicetree node, rather than implement
those drivers using the auxiliary bus. Wanting to avoid propagating this
naive/incorrect description of the hardware to the new pic64gx SoC is a
major motivating factor here.

As per the i.MX8MP TRM, section 14.2 "AUDIO_BLK_CTRL", table 14.2.3.1.1
"memory map", the definition of the EARC control register shows that the
EARC controller software reset is controlled via bit 0, while the EARC PHY
software reset is controlled via bit 1.
This means that the current definitions of IMX8MP_AUDIOMIX_EARC_RESET_MASK
and IMX8MP_AUDIOMIX_EARC_PHY_RESET_MASK are wrong since their values would
imply that the EARC controller software reset is controlled via bit 1 and
the EARC PHY software reset is controlled via bit 2. Fix them.

Pull SoC driver updates from Arnd Bergmann:
"Lots of platform specific updates for Qualcomm SoCs, including a new
TEE subsystem driver for the Qualcomm QTEE firmware interface.
Added support for the Apple A11 SoC in drivers that are shared with
the M1/M2 series, among more updates for those.
Smaller platform specific driver updates for Renesas, ASpeed,
Broadcom, Nvidia, Mediatek, Amlogic, TI, Allwinner, and Freescale
SoCs.
Driver updates in the cache controller, memory controller and reset
controller subsystems.
SCMI firmware updates to add more features and improve robustness.
This includes support for having multiple SCMI providers in a single
system.
TEE subsystem support for protected DMA-bufs, allowing hardware to
access memory areas that managed by the kernel but remain inaccessible
from the CPU in EL1/EL0"

Pull clk updates from Stephen Boyd:
"This is the usual collection of primarily clk driver updates.
The big part of the diff is all the new Qualcomm clk drivers added for
a few SoCs they're working on. The other two vendors with significant
work this cycle are Renesas and Amlogic. Renesas adds a bunch of clks
to existing drivers and supports some new SoCs while Amlogic is
starting a significant refactoring to simplify their code.
The core framework gained a pair of helpers to get the 'struct device'
or 'struct device_node' associated with a 'struct clk_hw'. Some
associated KUnit tests were added for these simple helpers as well.
Beyond that core change there are lots of little fixes throughout the
clk drivers for the stuff we see every day, wrong clk driver data that
affects tree topology or supported frequencies, etc. They're not found
until the clks are actually used by some consumer device driver.
New Drivers:
- Global, display, gpu, video, camera, tcsr, and rpmh clock
controller for the Qualcomm Milos SoC
- Camera, display, GPU, and video clock controllers for Qualcomm
QCS615
- Video clock controller driver for Qualcomm SM6350
- Camera clock controller driver for Qualcomm SC8180X
- I3C clocks and resets on Renesas RZ/G3E
- Expanded Serial Peripheral Interface (xSPI) clocks and resets on
Renesas RZ/V2H(P) and RZ/V2N
- SPI (RSPI) clocks and resets on Renesas RZ/V2H(P)
- SDHI and I2C clocks on Renesas RZ/T2H and RZ/N2H
- Ethernet clocks and resets on Renesas RZ/G3E
- Initial support for the Renesas RZ/T2H (R9A09G077) and RZ/N2H
(R9A09G087) SoCs
- Ethernet clocks and resets on Renesas RZ/V2H and RZ/V2N
- Timer, I2C, watchdog, GPU, and USB2.0 clocks and resets on Renesas
RZ/V2N
Updates:
- Support atomic PWMs in the PWM clk driver
- clk_hw_get_dev() and clk_hw_get_of_node() helpers
- Replace round_rate() with determine_rate() in various clk drivers
- Convert clk DT bindings to DT schema format for DT validation
- Various clk driver cleanups and refactorings from static analysis
tools and possibly real humans
- A lot of little fixes here and there to things like clk tree
topology, missing frequencies, flagging clks as critical, etc"

The BRCMSTB and BRCMSTB_RESCAL reset drivers are also
used in the BCM2712, AKA the RPi5. The RPi platforms
have typically used the ARCH_BCM2835, and the PCIe
support for this SoC can use this config which depends
on these drivers so enable building them when just that
arch option is enabled to ensure the platform works as
expected.
