[PATCH v2 4/5] ARM: dts: rockchip: Add shared file for audio related nodes for veyron boards

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Set i2s block to "okay", add sound node for max98090 with gpios for
HP and Mic detect and pinctrl, and add a max98090 device and ts3a227e to
the correct i2c bus.
