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.
It's been a long time since I looked at this code, but the series looks plausible, Acked-by: Stephen Warren swarren@nvidia.com
(I wonder why machine->gpio_int_mic_en was already parse but never used!)
Looking at the ventana schematics, it appears that the internal-mic signals was connected to a header and not an actual mic, so maybe we never had a proper internal-mic on any board but allowed one to be connected.
I guess cardhu may have a mic, judging by downstream kernel sources (I don't have cardhu schematics).
Anyway, looks good to me as well.
