seems my last mail is not send right (did not got it from mailinglist and it's not mapped in patchwork).
i tried this approach, but this does not work, with checking the new flag in mtk_hdmi_phy_power_on and only enabling tmds if this flag is not set results in same behaviour like without the Patch (horizontally distorted image flickering on 1280x1024)
- hdmi_phy->conf->hdmi_phy_enable_tmds(hdmi_phy);
+ if (!hdmi_phy->conf->pll_default_off)
+ hdmi_phy->conf->hdmi_phy_enable_tmds(hdmi_phy);
seems like tmds needs to be initially enabled and can only disabled later
regards Frank
