soc: mediatek: SVS: Fix MT8192 GPU node name

2023-07-11T17:39:40+00:00

[ Upstream commit 95094495401bdf6a0649d220dfd095e6079b5e39 ]

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.

soc: mediatek: mtk-svs: add missing MODULE_DEVICE_TABLE

2023-02-01T13:35:12+00:00

This patch adds missing MODULE_DEVICE_TABLE definition
which generates correct modalias for automatic loading
of this driver when it is built as an external module.

soc: mediatek: mtk-devapc: Switch to devm_clk_get_enabled()

2023-02-01T13:22:29+00:00

This driver does exactly devm_clk_get() and clk_prepare_enable() right
after, which is exactly what devm_clk_get_enabled() does: clean that
up by switching to the latter.

This commit brings no functional changes.

soc: mtk-svs: mt8183: refactor o_slope calculation

2023-01-31T13:40:55+00:00

The o_slope value is dependent of the o_slope_sign, refactor code to get
rid of unnecessary if constructs.

soc: mediatek: mtk-svs: delete superfluous platform data entries

2023-01-31T13:30:24+00:00

The platform name and efuse parsing function pointer are only used while
probing the device. Use them from the svs_platform_data struct instead.

soc: mediatek: mtk-svs: move svs_platform_probe into probe

2023-01-31T13:24:58+00:00

Moving svs_platform_probe into driver probe function will allow us to
reduce svs_platform members. This will be done in a follow-up patch.

soc: mediatek: mtk-svs: improve readability of platform_probe

2023-01-31T13:24:38+00:00

If a compatible misses a match data entry, then something is wrong in
the development phase, we don't need to check for that at runtime.

soc: mediatek: mtk-svs: clean up platform probing

2023-01-31T13:24:17+00:00

We only ever call the SoC specific probe function from
svs_platform_probe. No need to carry that function in a global
datastructure around.

soc: mediatek: mtk-svs: keep svs alive if CONFIG_DEBUG_FS not supported

2023-01-31T13:23:55+00:00

Some projects might not support CONFIG_DEBUG_FS but still needs svs to be
alive. Therefore, enclose debug cmd codes with CONFIG_DEBUG_FS to make sure
svs can be alive when CONFIG_DEBUG_FS not supported.

soc: mediatek: mtk-svs: Use pm_runtime_resume_and_get() in svs_init01()

2023-01-31T13:23:05+00:00

svs_init01() calls pm_runtime_get_sync() and added fail path as
svs_init01_finish to put usage_counter. However, pm_runtime_get_sync()
will increment usage_counter even it failed. Fix it by replacing it with
pm_runtime_resume_and_get() to keep usage counter balanced.
