Thanks, Russell.

BTW, can you take a look at the following two patches, or are they
already in your queue?

imx-drm: imx-drm-core: Fix imx_drm_encoder_get_mux_id
https://lkml.org/lkml/2014/4/7/58

mx-drm: imx-tve: correct DDC property name to 'ddc-i2c-bus'
('i' is missing from the prefix word, and it should be 'imx-drm')
