Thierry Reding d780537f9b drm/tegra: sor: Fix hang on Tegra124 eDP ... The SOR0 found on Tegra124 and Tegra210 only supports eDP and LVDS and therefore has a slightly different clock tree than the SOR1 which does not support eDP, but HDMI and DP instead. Commit e1335e2f0c ("drm/tegra: sor: Reimplement pad clock") breaks setups with eDP because the sor->clk_out clock is uninitialized and therefore setting the parent clock (either the safe clock or either of the display PLLs) fails, which can cause hangs later on since there is no clock driving the module. Fix this by falling back to the module clock for sor->clk_out on those setups. This guarantees that the module will always be clocked by an enabled clock and hence prevents those hangs.
