Re: OMAP4 HDMI PHY bug work-around for stable

[Tomi Valkeinen]

Hi,

I haven't seen these merged nor any comment for these. Perhaps
stable@xxxxxxxxxx was wrong address, so adding stable@xxxxxxxxxxxxxxx
too.

I have added one additional fix into for-3.2-stable branch, which fixes
a problem with panel detection that the GPIO changes brought.
