Hi Maxime,

Today I tried on this series on next-20180228, but resolution switching doesn't really work. The reason for this is use of clk_set_rate_exclusive() in sun4i_tcon1_mode_set(). If I revert it to ordinary clk_set_rate() it works ok. I investigated a bit and it seems that clocks stays at first set even if tcon (the owner of exclusive lock) request the new one. Example:
[ 69.325732] TCON clk wanted: 148500000 [ 69.325740] TCON real clk: 69272728 [ 69.325770] HDMI clk wanted: 148500000 [ 69.325773] HDMI real clk: 138545455 [ 69.325815] HDMI PHY clk wanted: 148500000 [ 69.325819] HDMI PHY real clk: 138545454
Is there anything I can do to help debug this?
Best regards, Jernej
