Attached is a revised version of my patch to add AT32 to ASoC. This cleans most of the style issues associated with the previous patch. Also fixes an issue with the playpaq_wm8510.c code depending on a non-released patch to th AT32 portmux support. Patch is against 2.6.24.3.atmel.3 kernel, the latest AVR32 kernel Atmel has released, with the linux-2.6-asoc patches from when v2.6.24 was tagged also applied. [Fixed up minor checkpatch issues and updated for current kernels -- broonie] Signed-off-by: Geoffrey Wossum <gwossum@acm.org> Signed-off-by: Mark Brown <broonie@opensource.wolfsonmicro.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
