My current patch stack for imx-drm related stuff looks like this at
present:

drm: bridge/dw_hdmi: place PHY into low power mode when disabled
drm: bridge/dw_hdmi: start of support for pixel doubled modes
drm: bridge/dw_hdmi: remove CEC engine register definitions
drm: bridge/dw_hdmi-cec: add Designware HDMI CEC driver
cec: add HDMI CEC input driver
cec: add HDMI CEC core driver
drm: bridge/dw_hdmi: replace CTS calculation for the ACR
drm: bridge/dw_hdmi: remove ratio support from ACR code
drm: bridge/dw_hdmi: adjust pixel clock values in N calculation
drm: bridge/dw_hdmi: avoid being recursive in N calculation
drm: bridge/dw_hdmi-ahb-audio: allow larger buffer sizes
drm: bridge/dw_hdmi-ahb-audio: basic support for multi-channel PCM audio
drm: bridge/dw_hdmi-ahb-audio: parse ELD from HDMI driver
drm: bridge/dw_hdmi-ahb-audio: add audio driver
drm: bridge/dw_hdmi: improve HDMI enable/disable handling
drm: bridge/dw_hdmi: add connector mode forcing
drm: bridge/dw_hdmi: add support for interlaced video modes
gpu: imx: fix support for interlaced modes
gpu: imx: simplify sync polarity setting

I haven't yet decided what, if anything, from that stack I'm going to
try to get into the next merge window.  Given the lack of interest last
time I posted these patches, I'm loosing interest myself in trying to
get them merged, especially ones which are getting on for being 2 years
old.
