[RFC PATCH 00/13] Add support for Tegra DPAUX pinctrl

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

 



The Display Port Auxiliary (DPAUX) channel pads can be shared with an
internal I2C controller. Add pinctrl support for these pads so that the
I2C controller can request and use these pads.
