Subject: Re: [PATCH 1/1] drm/rockchip: vop: add the definition of dclk_pol【请注意，邮件由linux-rockchip-bounces+sandy.huang=rock-chips.com@...ts.infradead.org代发】
Reviewed-by: Sandy Huang <hjc@...k-chips.com>

> Some VOP's (such as px30) dclk_pol bit is at the last.
> So it is necessary to distinguish dclk_pol and pin_pol.
