Hello, This small series adds audio route for built-in microphone on NVIDIA Tegra boards that use WM8903 CODEC. In particular this is needed in order to unmute internal microphone on Acer A500 tablet device. I'm planning to send out the device tree for the A500 for 5.8, so will be nice to get the microphone sorted out. Please review and apply, thanks in advance.
