[PATCH v1] drm/tegra: dc: Don't set PLL clock to 0Hz

2021-03-02 Thread Dmitry Osipenko
RGB output doesn't allow to change parent clock rate of the display and PCLK rate is set to 0Hz in this case. The tegra_dc_commit_state() shall not set the display clock to 0Hz since this change propagates to the parent clock. The DISP clock is defined as a NODIV clock by the tegra-clk driver and a
