[PATCH] drm/sun4i: tcon: Set min division of TCON0_DCLK to 1.

2019-11-14 Thread Tian Yunhao
The datasheet of V3s (and various other chips) wrote that TCON0_DCLK_DIV can be >= 1 if only dclk is used, and must >= 6 if dclk1 or dclk2 is used. As currently neither dclk1 nor dclk2 is used (no writes to these bits), let's set minimal division to 1. If this minimal division is 6, some common do
