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
