27dc882644 Merge branch 'master' of https://source.denx.de/u-boot/custodians/u-boot-sunxi
Please pull the second part of the sunxi pull request for this cycle.
Another bunch of patches that replace old-school U-Boot hacks with
proper DM based code, this time for the raw NAND flash driver, and the
USB PHY VBUS detection code. Plus two smaller patches that were sitting
in my inbox for a while.

Gitlab CI passed. In lack of some supported board with NAND flash I
couldn't really test this part, but apparently this was tested by the
reviewer. I briefly ran the branch on some boards with USB-OTG, and
this still worked.

fe3a77cb15 Merge branch 'for-2023.07' of https://source.denx.de/u-boot/custodians/u-boot-mpc8xx
This pull request adds support for the last CPU board from
CS GROUP France (previously CSSI).

That CPU board called CMPCPRO has a mpc8321E CPU (Family PQII PRO hence
its name) and can be plugged in place of the CMPC885 board.

In order to support that new board, the following changes are included
in this series:
- Make the mpc8xx watchdog driver more generic for reusing it
with mpc83xx
- Fix various small problems on mpc83xx platform
- Add a GPIO Driver for QE GPIOs
- Add support for mpc832x into mpc83xx SPI driver
- Refactor existing board code that will be shared with new board
- Add the new board

59c1ddd2c5 clk: sunxi: Add NAND clocks and resets
Currently NAND clock setup is done in board code, both in SPL and in
U-Boot proper. Add the NAND clocks/resets here so they can be used by
the "full" NAND driver once it is converted to the driver model.

The bit locations are copied from the Linux CCU drivers.

6737771600 rockchip: rk3588: Add support for sdmmc clocks in SPL
Booting from sdmmc on RK3588 currently works because of a workaround in
the device tree, clocks are reordered so that the driver use ciu-sample
instead of ciu, and the BootRom initializes sdmmc clocks before SPL is
loaded into DRAM.

The sdmmc clocks are normally controlled by TF-A using SCMI. However,
there is a need to control these clocks in SPL, before TF-A has started.

This adds a rk3588_scru driver to control the sdmmc clocks in SPL before
TF-A has started, using scru regs. It also adds a small glue driver to
bind the scmi clock node to the rk3588_scru driver in SPL.

Add clock tables for R8A779G0 V4H SoC from Linux next
commit 058f4df42121 ("Add linux-next specific files for 20230228")

There is an adjustment to the clock tables to make them easier suitable
for U-Boot, PLL2 is not treated as GEN4 PLL type PLL2_VAR, but rather a
plain PLL2. This should be sufficient until PLL2_VAR is implemented in
the clock core.

3e01ed8e0f clk: renesas: Update R-Car Gen3 driver Gen4 support
Update R-Car Gen4 support in Gen3 clock driver. This patch renames the
V3U clock parts to Gen4 and extends them by new PLL2, PLL3, PLL4, PLL6
as well as SDSRC clock which use undocumented bits so far, and RPCSRC
clock which uses its own more capable divider table. The Gen4 module
standby and reset tables are also updated.

This patch makes use of union to alias Gen3 and more extensive Gen4
PLL tables, as the driver cannot ever be instantiated on hardware
that would identify itself as both Gen3 and Gen4.

The V3U clock driver is updated to match Gen4 clock driver behavior,
it is augmented with a more extensive PLL table and a valid MODEMR
register offset.

This supersedes "clk: renesas: Introduce R-Car Gen4 CPG driver"
from Hai Pham as the R-Car Gen3 and Gen4 clock core drivers are
extremely similar. That implementation was in turn based on Linux
commit 470e3f0d0b15 ("clk: renesas: rcar-gen4: Introduce R-Car Gen4 CPG driver")
by Yoshihiro Shimoda .

3efdf01fa4 clk: renesas: Always select DM_RESET to prevent inobvious failure of rst_gen3 subdriver
The CLK_RCAR_GEN3 registers two subdrivers, clk_gen3 and rst_gen3.
The former depends on the clock framework, which is always enabled
in this context of clock framework driver, while the later depends
on reset framework which may not always be enabled.

Ensure the reset framework is also always enabled to prevent inobvious
early boot time bind failure of the CPG driver, which leads to system
showing no activity and is difficult to debug.

Note that one possible approach to debug this is to use CONFIG_DEBUG_UART
and add debug printascii()s into the drivers/clk/renesas/clk-rcar-gen3.c .

6d87b1572f arm64: zynqmp: Add missing ZYNQMP_FIRMWARE dependencies
There are missing Kconfig dependencies in the code which is using
firmware interface.
The commit 71efd45a5f ("arm64: zynqmp: Change firmware dependency")
add option to also disable ZYNQMP_FIRMWARE. But not all Kconfig
dependencies were properly described and also sdhci and gem drivers
didn't protect the code properly.
So, add the missing ZYNQMP_FIRMWARE dependencies.

The IMX8MN platform does not have any video processing unit (VPU), and
indeed in the reference manual (document IMX8MNRM Rev 2, 07/2022) there
is no occurrence of its pll. From an analysis of the code and the RM
itself, I think vpu pll is used instead of m7 alternate pll, probably
for copy and paste of code taken from modules of similar architectures.
