This patch series add the support for the MediaTek MT8365 EVK Board [1].
Most of the code have been copied/adapted from Linux tag v6.7-rc2.
For now we only enable/test these features:
Boot, UART, Watchdog and MMC.
[trini: This includes two clocks not listed in the Linux binding, which
needs resyncing later]
This patch adds clock driver support for MediaTek MT8365 SoC.
The changes are based on the Linux source code tag v6.7-rc2.
clk-mt8365.c has been written based on these kernel files:
- clk-mt8365.c (a96cbb146a9736f501fe66ebda6a9018735e5e8a)
- clk-mt8365-apmixedsys.c (65c9ad77cbc0eed78db94d80041aba675cfbdfa9)
And adapted following the clk attributes supported by U-Boot.

It's possible for composite clocks to have a divider that does not
implement set_rate() operation. For example, sandbox_clk_composite()
registers composite clock with a divider that only has get_rate().
Currently clk_composite_set_rate() only checks thate rate_ops are
present, so for sandbox it will cause NULL dereference during
clk_set_rate().
This patch adds rate_ops->set_rate check tp clk_composite_set_rate().

Clock changes for 2024.01-rc2
This contains several fixes for the clock core.
In clk_enable()/clk_disable() functions, when CCF is activated,
we must pass a private clk struct to enable()/disable() ops functions.
Otherwise, the use of a container_of() construction within these ops
should be banned. Because passing a non-private clk struct to
container_of() results in an out of range error.
At the moment, clk-mux, clk-fixed-factor, clk-gate and possibly other
clocks use container_of() in their enable()/disable() functions.
Therefore, for these functions to work correclty, private clk struct
must be passed.

In commit 5c5992cb90 ("clk: Add debugging for return values"), a
temporary storage variable was added around the ops->get_rate() call
inside clk_get_rate(), so that the result could be passed through
log_ret.
This temporary variable was declared as an int, yet when we look in
struct clk_ops, we can see this needs to be a ulong:
ulong (*get_rate)(struct clk *clk);
This was resulting in a signed to unsigned casting error on our
builds, where a clock value of 0xABCDABCD was being incorrectly cast
to 0xFFFFFFFFABCDABCD.

This adds the remaining code bits to teach U-Boot about Allwinner's
newest SoC generation. This was introduced with the RISC-V based
Allwinner D1 SoC, which actually shares a die with the ARM cores versions
called R528 (BGA, without DRAM) and T113s (QFP, with embedded DRAM).
This adds the new Kconfig stanza, using the two newly introduced symbols
for the new SoC generation and pincontroller. It also adds the new symbols
to the relavent code places, to set all the hardcoded bits directly.
We need one DT override:
The ARM core version of the DT specifies the CPUX watchdog as
"reserved", which means it won't be recognised by U-Boot. Override this
in our generic sunxi-u-boot.dtsi, to let U-Boot pick up this watchdog,
so that the generic reset driver will work.

This driver provides clock and reset control for the Renesas R9A07G044L
(RZ/G2L) and R9A07G044C (RZ/G2LC) SoC. It consists of two parts:
* driver code which is applicable to all SoCs in the RZ/G2L family.
* static data describing the clocks and resets which are specific to the
R9A07G044{L,C} SoCs. The identifier r9a07g044 (without a final letter)
is used to indicate that both SoCs are supported.
clk_set_rate() and clk_get_rate() are implemented only for the clocks
that are actually used in u-boot.
The CPG driver is marked with DM_FLAG_PRE_RELOC to ensure that its bind
function is called before the SCIF (serial port) driver is probed. This
is required so that we can de-assert the relevant reset signal during
the serial driver probe function.
This patch is based on the corresponding Linux v6.5 driver
(commit 52e12027d50affbf60c6c9c64db8017391b0c22e).
