* Initialize clock tree for audio * Add GPIO base definitions * Add audio GPIO definitions * Define platform data for WM8903 and ASoC machine driver * Add special case for Kaen to handle HP_MUTE GPIO * Register platform devices for audio * Update pinmux to cater for new GPIOs used for audio
Signed-off-by: Stephen Warren swarren@nvidia.com --- NOTE: This patch relies on the git pull request I sent out earlier today (from Mark's ASoC tegra branch, to update the platform data structure etc.)
