[PATCH v2 4/9] ARM64: dts: meson-gxbb: nanopi-k2: add card regulator settle times

2017-08-21 Thread Jerome Brunet
Changing the card voltage on the nanopi-k2 is not instantaneous, especially when switching from 3.3v to 1.8v. It take at least 3ms for the regulator to go from 3.3v to 1.8v. Add margin to that to make sure we don't upset the sdcard during the voltage switch Fixes: 9bc7ffb08daf ("arm64: dts:
