[PATCH v2 1/5] drm/rockchip: vop: get rid of register init table
From: Mark Yao
Date: Tue Jul 11 2017 - 22:04:19 EST
Register init table use un-document define, it is unreadable,
And sometimes we only want to update tiny bits, init table
method is not friendly, it's diffcult to reuse for difference
chips.
