soc: mediatek: SVS: Fix MT8192 GPU node name

2023-06-09T14:34:47+00:00

Device tree node names should be generic. The planned device node name
for the GPU, according to the bindings and posted DT changes, is "gpu",
not "mali".

Fix the GPU node name in the SVS driver to follow.

Remove .owner field if calls are used which set it automatically.

./drivers/soc/mediatek/mtk-mutex.c:1054:3-8: No need to set .owner here. The core will do it.

soc: mediatek: mtk-pmic-wrap: Add support for companion PMICs

2023-05-29T13:26:44+00:00

Some PMICs are designed to work with a companion part, which provides
more regulators and/or companion devices such as LED controllers,
display backlight controllers, battery charging, fuel gauge, etc:
this kind of PMICs are usually present in smartphone platforms, where
tight integration is required.

2023-05-29T13:26:44+00:00

The PMIC read test is performed in two places: pwrap_init_dual_io()
and pwrap_init_sidly().
In preparation for adding support for PMICs requiring a companion
part, move this sequence to a new function pwrap_pmic_read_test().

Merge tag 'devicetree-for-6.4-2' of git://git.kernel.org/pub/scm/linux/kernel/git/robh/linux

2023-04-27T17:09:05+00:00

Pull more devicetree updates from Rob Herring:

 - 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.

soc: mediatek: mtk-svs: Add explicit include for cpu.h

2023-04-13T22:46:35+00:00

Removing the include of cpu.h from of_device.h (included by
of_platform.h) causes an error:

drivers/soc/mediatek/mtk-svs.c:2134:41: error: implicit declaration of function 'get_cpu_device'; did you mean 'get_swap_device'? [-Werror=implicit-function-declaration]

of_platform.h is still needed for of_find_device_by_node().

soc: mediatek: Kconfig: Add MTK_CMDQ dependency to MTK_MMSYS

2023-04-11T15:15:10+00:00

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.
