Subject: [PATCH v2 2/8] drm/rockchip: vop: add lut_size for RK3368 vop_data
Date: Fri, 5 Sep 2025 10:56:26 +0800 [thread overview]
Message-ID: <20250905025632.222422-3-cn.liweihao@gmail.com> (raw)

VOP driver need a correct lut_size to work normally. According to
rockchip downstream kernel source [1], the lut_size is 0x400.
