Subject: [PATCH] ARM: dts: tegra20-glide: Add bindings for microphone
|
|
|
|
Mic requires additional GPIOs to work:
|
|
- MICBIAS1: internal MICBIAS
|
|
- MICBIAS2: external (headphone) MICBIAS
|
|
- EAR_SEL: to choose between internal and external mic
|
|
|
|
Also GPIO 1 on Wolfson chip needs to be asserted.
|
|
Make it on by default.
|
