This could be

https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=0fc721b2968e3cadec520c60d2fc63498d865055 (add support for mt2701/mt7623).

It uses existing framework which calls mtk_hdmi_phy_enable_tmds by default in mtk_hdmi_phy_power_on.

Another way to fix it maybe not enabling it (use the flag in mtk_hdmi_phy_power_on) there instead of disabling after enabling it.

Maybe this is less hacky than current way (as ck hu pointed in v2).
