[PATCH 2/6] ARM: dts: am437x-gp-evm: Add pinctrl for unused_pins

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

 



From: Dave Gerlach <d-gerlach@xxxxxx>

There are several pins on this EVM that are not in use but they can
still draw power if misconfigured. Create a pinctrl entry for these pins
and configure each one for optimal power savings.

[t-kristo@xxxxxx: converted to use AM4372_IOPAD macro]
