My patch ignored the grf-clock when doing the grf-based init. All clocks are on during boot and I guess the hdmi-driver did disable it after its probe. The phy_power_on functions did handle it correctly already, so it was only happening with hdmi connected on boot. Btw. do you plan on submitting your ov13850 driver soonish?
