[RFC v4 13/14] ARM: dts: exynos: Switch the buck8 to GPIO mode on Odroid U3

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

 




Switch the control of buck8 to GPIO mode. It is faster than I2C/register
mode and it is the easiest way to disable it (regulator state is a
logical OR state of GPIO and register value).
