[alsa-devel] [PATCHv2 0/9] DT support for N900 soundcard (rx51-audio)

This patchset adds DT support in rx51-audio. I tested it on my
Nokia N900 and was able to play a wav file using aplay. I have
not tested the whole functionality, but output via speakers,
headphones and the related enable controls seem to work.

Changes since PATCHv1 [0]:
 * drop "ASoC: tlv320aic3x: fix shared reset pin for DT"
   (already applied)
 * drop "ASoC: RX-51: Convert to table based DAPM setup"
   (similar patch was applied to -next)
 * remove useless "card->dev = NULL;" from first patch
 * split patches from into smaller chunks
 * introduce new patch, which fixes a checkpatch warning
 * use gpiod API, which reduces the DT specific bits of
   the driver
 * rebase to newer -next checkout
