[PATCH 4/6] drm: tegra: remove redundant tegra2_tmds_config entry

Lucas Stach dev at lynxeye.de
Wed Dec 19 13:38:55 PST 2012


The 720p and 1080p entries are completely redundant, as we are matching
the table entries against <=pclk.
Also generalize the comment, as we are using those table entries even
when driving other modes than the standard TV ones.
