Thanks, I'll apply this.

If you have time, can you revisit this? The current omapdss master
branch has some cleanups for the cpu check:

[PATCH v2] OMAPDSS: Do not require a VDDS_DSI regulator on am35xx

2012-08-15 Thread Raphael Assenat
On our AM3505 based board, dpi.c complains that there is no VDSS_DSI regulator
and the framebuffer cannot be enabled. However, this check does not seem to
apply to AM3505/17 chips.

Taking into account comments received after my first patch[1], I have added
entries to dss_features.c to support the am35xx soc. Then in dpi.c, instead
of using cpu_is_omap34xx() and soc_is_am35xx(), a call to dss_has_feature()
is used.
