soc: mediatek: Support MT8188 VDOSYS1 in mtk-mmsys
- Add register definitions for MT8188
- Add VDOSYS1 routing table
- Update MUTEX definitions accordingly
- Set VSYNC length from 0x40 (default) to 1 since ETHDR is bypassed

soc: mediatek: svs: Add support for MT8186 SoC
MT8186 svs has a number of banks which used as optimization of opp
voltage table for corresponding dvfs drivers.
MT8186 svs big core uses 2-line high bank and low bank to optimize the
voltage of opp table for higher and lower frequency respectively.

385903a7ec SoC driver updates for 6.7
The highlights for the driver support this time are
 
  - Qualcomm platforms gain support for the Qualcomm Secure Execution
    Environment firmware interface to access EFI variables on certain
    devices, and new features for multiple platform and firmware drivers.
 
  - Arm FF-A firmware support gains support for v1.1 specification features,
    in particular notification and memory transaction descriptor changes.
 
  - SCMI firmware support now support v3.2 features for clock and DVFS
    configuration and a new transport for Qualcomm platforms.
 
  - Minor cleanups and bugfixes are added to pretty much all the active
    platforms: qualcomm, broadcom, dove, ti-k3, rockchip, sifive, amlogic,
    atmel, tegra, aspeed, vexpress, mediatek, samsung and more.
    In particular, this contains portions of the treewide conversion to
    use __counted_by annotations and the device_get_match_data helper.

630cc5e1e6 soc/mediatek: mtk-mmsys: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

soc: mediatek: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

cb6fe2ceb6 Devicetree updates for v6.4, part 2:
- First part of DT header detangling dropping cpu.h from of_device.h
   and replacing some includes with forward declarations. A handful of
   drivers needed some adjustment to their includes as a result.
 
 - Refactor of_device.h to be used by bus drivers rather than various
   device drivers. This moves non-bus related functions out of
   of_device.h. The end goal is for of_platform.h and of_device.h to stop
   including each other.
 
 - Refactor open coded parsing of "ranges" in some bus drivers to use DT
   address parsing functions
 
 - Add some new address parsing functions of_property_read_reg(),
   of_range_count(), and of_range_to_resource() in preparation to convert
   more open coded parsing of DT addresses to use them.
 
 - Treewide clean-ups to use of_property_read_bool() and
   of_property_present() as appropriate. The ones here are the ones
   that didn't get picked up elsewhere.

The mtk-mmsys and mutex drivers do have a dependency on MTK_CMDQ,
even though both can work with *or* without it: since CMDQ support
can be enabled either as module or as built-in, it is necessary to
add a depends rule in Kconfig, so that we disallow building both
mtk-mmsys and mtk-mutex as built-in if mtk-cmdq-helper is built as
a module, otherwise obvious linker issues appear.

The MT8173 SoC has 64 MMSYS resets, split in two contiguous 32-bits
registers, MMSYS_SW0_RST_B (0x140) and MMSYS_SW1_RST_B (0x144), as
also stated in the downstream kernel for the Amazon Fire TV 2

Please note that managing more than 32 reset bits is supported since commit

2a0a8d8700 soc: mediatek: mtk-mmsys: Split out MT8173 mmsys DDP routing table
MT2701, MT2712 and MT8173 were relying on a "default" DDP I/O routing
table, describing all of the possible connections between display block
components: while this is definitely working it's suboptimal for the
actual routing description, as we may be enabling outputs and inputs
that are not needed, possibly impacting on actual DDP performance other
than slightly prolonging boot times by having to parse a table that is
bigger than needed.

Seen that all of the other supported SoCs have got their own table and
seen that a comment in mtk-mmsys.h explicitly mentions that the wanted
way is to have one table per SoC, create a new routing table that is
specifically tailored to MT8173 and, while at it, remove mentions to
said SoC from the comment in mtk-mmsys.h.

Now that the mtk-cmdq.h header contains inline functions for cases
in which the driver is not enabled (either module or built-in), we
can safely go on with cleaning up ifdefs for CMDQ handling.

This also shows in a clearer manner that writing through CMDQ HW is
optional and used only for performance purposes when/where wanted,
needed and/or required.

8af1f6b5bc soc: mediatek: add cmdq support of mtk-mmsys config API for mt8195 vdosys1
Add cmdq support for mtk-mmsys config API.
The mmsys config register settings need to take effect with the other
HW settings(like OVL_ADAPTOR...) at the same vblanking time.

If we use CPU to write the mmsys reg, we can't guarantee all the
settings can be written in the same vblanking time.
Cmdq is used for this purpose. We prepare all the related HW settings
in one cmdq packet. The first command in the packet is "wait stream done",
and then following with all the HW settings. After the cmdq packet is
flush to GCE HW. The GCE waits for the "stream done event" to coming
and then starts flushing all the HW settings. This can guarantee all
the settings flush in the same vblanking.

e6c7e6216d soc: mediatek: Add all settings to mtk_mmsys_ddp_dpi_fmt_config func
The difference between MT8186 and other ICs is that when modifying the
output format, we need to modify the mmsys_base+0x400 register to take
effect. So when setting the dpi output format, we need to call
mtk_mmsys_ddp_dpi_fmt_config to set it to MT8186 synchronously.

Commit a071e52f75d1 ("soc: mediatek: Add mmsys func to adapt to dpi
output for MT8186") lacked some of the possible output formats and also
had a wrong bitmask.

Add the missing output formats and fix the bitmask.

While at it, also update mtk_mmsys_ddp_dpi_fmt_config() to use generic
formats, so that it is slightly easier to extend for other platforms.

2778caedb5 soc: mediatek: Let PMIC Wrapper and SCPSYS depend on OF
With the following configuration options:
CONFIG_OF is not set
CONFIG_MTK_PMIC_WRAP=y
CONFIG_MTK_SCPSYS=y
we get the following build warnings:

  CC      drivers/soc/mediatek/mtk-pmic-wrap.o
drivers/soc/mediatek/mtk-pmic-wrap.c:2138:34: warning: ‘of_pwrap_match_tbl’ defined but not used [-Wunused-const-variable=]

drivers/soc/mediatek/mtk-scpsys.c:1084:34: warning: ‘of_scpsys_match_tbl’ defined but not used [-Wunused-const-variable=]

Looking at the code, both drivers can only bind to OF-defined device
nodes, so these drivers are useless without OF and should therefore
depend on it.

Also drop of_match_ptr() from both drivers. We already know what it
will resolve to, so we might as well save cpp some work.

Developers or QA teams who wish to test-build the code can still do
so by enabling CONFIG_OF, which is available on all architectures and
has no dependencies.

c749d676a3 soc: mediatek: SVS: Use DEFINE_SIMPLE_DEV_PM_OPS for svs_pm_ops
When building this driver for an architecture that does not support
CONFIG_PM_SLEEP, such as hexagon, the following warnings occur:

  drivers/soc/mediatek/mtk-svs.c:1481:12: error: unused function 'svs_suspend' [-Werror,-Wunused-function]
  static int svs_suspend(struct device *dev)

  static int svs_resume(struct device *dev)
             ^
  2 errors generated.

This happens because SIMPLE_DEV_PM_OPS uses SET_SYSTEM_SLEEP_PM_OPS,
which evaluates to nothing when CONFIG_PM_SLEEP is not set, leaving the
functions unused in the eyes of the compiler.

This problem was rectified in commit 1a3c7bb088 ("PM: core: Add new
*_PM_OPS macros, deprecate old ones") with new macros. Use
DEFINE_SIMPLE_DEV_PM_OPS to fix the warning while not changing
svs_pm_ops when CONFIG_PM_SLEEP is set.

This also ensures that the SRAM is actually powered and that we're
