[PATCH v2 07/16] drm: rcar-du: Use LVDS PLL clock as dot clock when possible

2018-09-14 Thread Laurent Pinchart
On selected SoCs, the DU can use the clock output by the LVDS encoder PLL as its input dot clock. This feature is optional, but on the D3 and E3 SoC it is often the only way to obtain a precise dot clock frequency, as the other available clocks (CPG-generated clock and external clock) usually have
