The mmsys driver supports only MT8173 device for now, but like other system
controllers is an important piece for other Mediatek devices. Actually
it depends on the mt8173 clock specific driver but that dependency is
not real as it can build without the clock driver. Instead of depends on
a specific model, make the driver depends on the generic ARCH_MEDIATEK and
enable by default so other Mediatek devices can start using it without
flood the Kconfig.

Add support for the Meson GX SoCs to the meson-ee-pwrc driver.
The power domains on the GX SoCs are very similar to G12A. The only
known differences so far are:
- The GX SoCs do not have the HHI_VPU_MEM_PD_REG2 register (for the
VPU power-domain)
- The GX SoCs have an additional reset line called "dvin"

This adds support for the power domains on Meson8/Meson8b/Meson8m2.
Meson8 doesn't use any reset lines while Meson8b and Meson8m2 use the
same set of reset lines (which is different from the newer SoCs).
Add dedicated compatible strings for Meson8, Meson8b and Meson8m2 to
support these differences.
Notable differences between Meson8 and G12A are:
- there is no HHI_VPU_MEM_PD_REG2 on the 32-bit SoCs
- the Meson8b datasheet describes an "audio DSP memory" power domain
which is used for the hardware audio decoder
- the "amlogic,ao-sysctrl" only includes the power management related
registers on the 32-bit SoCs, meaning the for example the
AO_RTI_GEN_PWR_SLEEP0 register is at offset (0x2 << 2) rather than
(0x3a << 2). As result of this (0x38 << 2) is subtracted from the
register offsets, which is the start of the power management related
registers.

dynamic memory allocation is allowed once callers are added. Change
it to kcalloc for now, if anyone gets a warning about calling this in

The variable is not used anywhere, so removing the assignment seems
to be the correct workaround. After spotting what seemed to be
some confusion about address spaces, I ran the file through sparse,
which showed more warnings:
drivers/soc/fsl/dpio/qbman-portal.c:756:42: warning: incorrect type in argument 1 (different address spaces)

Here, the problem is passing a token from memremap() into __raw_readl(),
which is only defined to work on MMIO addresses but not RAM. Turning
this into a simple pointer dereference avoids this warning as well.

In the actual implementation the same compatible string
"mediatek,<chip>-mmsys" is used to bind the clock drivers
(drivers/soc/mediatek) as well as to the gpu driver
(drivers/gpu/drm/mediatek/mtk_drm_drv.c). This ends with the problem
that the only probed driver is the clock driver and there is no display
at all.
In any case having the same compatible string for two drivers is not
correct and should be fixed. To fix this, and maintain backward
compatibility, we can consider that the mmsys driver is the top-level
entry point for the multimedia subsystem, so is not a pure clock
controller but a system controller, and the drm driver is instantiated
by that MMSYS driver.

There is no strong reason for this to use CLK_OF_DECLARE instead of
being a platform driver. Plus, MMSYS provides clocks but also a shared
register space for the mediatek-drm and the mediatek-mdp
driver. So move the MMSYS clocks to a new platform driver and also
create a new MMSYS platform driver in drivers/soc/mediatek that
instantiates the clock driver.

This tag contains the patches I'd like to target for 5.7. It has a handful of
new features:
* Partial support for the Kendryte K210. There are still a few outstanding
issues that I have patches for, but I don't actually have a board to test
them so they're not included yet.
* SBI v0.2 support.
* Fixes to support for building with LLVM-based toolchains. The resulting
images are known not to boot yet.
This builds and boots for me. There is one merge conflict, it's just a Kconfig
merge issue. I can publish a resolved branch if you'd like.
I don't anticipate a part two, but I'll probably have something early in the
RCs to finish up the K210 support.

Pull RISC-V updates from Palmer Dabbelt:
"This contains a handful of new features:
- Partial support for the Kendryte K210.
There are still a few outstanding issues that I have patches for,
but I don't actually have a board to test them so they're not
included yet.
- SBI v0.2 support.
- Fixes to support for building with LLVM-based toolchains. The
resulting images are known not to boot yet.
I don't anticipate a part two, but I'll probably have something early
in the RCs to finish up the K210 support"

Add support for the Kendryte K210 RISC-V SoC. For now, this support
only provides a simple sysctl driver allowing to setup the CPU and
uart clock. This support is enabled through the new Kconfig option
SOC_KENDRYTE and defines the config option CONFIG_K210_SYSCTL
to enable the K210 SoC sysctl driver compilation.
The sysctl driver also registers an early SoC initialization function
allowing enabling the general purpose use of the 2MB of SRAM normally
reserved for the SoC AI engine. This initialization function is
automatically called before the dt early initialization using the flat
dt root node compatible property matching the value "kendryte,k210".
