[PATCH v10,1/3] soc: mediatek: Add all settings to mtk_mmsys_ddp_dpi_fmt_config func
Posted by xinlei.lee@mediatek.com 4 days, 16 hours ago
From: Xinlei Lee <xinlei.lee@mediatek.com>

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 mmsys_func to set
it to MT8186 synchronously.
Adding mmsys all the settings that need to be modified with dpi are for mt8186.

Fixes: a071e52f75d1 ("soc: mediatek: Add mmsys func to adapt to dpi output for MT8186")
