[PATCH] drm/meson: add mode selection limits against specific SoC revisions

2020-04-21 Thread Neil Armstrong
The Amlogic S805X/Y uses the same die as the S905X, but with more limited graphics capabilities. This adds a soc version detection adding specific limitations on the HDMI mode selections. Here, we limit to HDMI 1.3a max HDMI PHY clock frequency. Signed-off-by: Neil Armstrong ---
