sure.
1) I am not convinced with idea of exposing a generic interface in a
place like exynos_drm_hdmi.c
which holds good for all existing and future versions of mixer IP.
Exposing it from exynos_mixer.c
is even worse.
2) Since we are setting video timing registers based drm_display_mode,
I ruled out the option of
supporting non-standard resolutions. Please correct me if I am wrong.
3) I cleaned up many phyconfigs, added in the mentioned patches, which
are not required by any resolution
meeting the mixer criteria.
I examined all possible standard resolutions (in drm_edid_modes.h)
which passes through
the restrictions of mixer and hdmiphy and put them under
hdmi_v14_modes. Please let me know if
I missed any of that. IMHO purpose of the above chromium patches is
still intact.

Rahul Sharma.
