dts: arm64: db820c: add pmic pins specific dts file (50784e61) · Commits · 戴 / test

This patch adds pmic specific dts which are configured specially for db820c. One of such pin is GPIO_F on the Low Speed expansion which has default output voltage of 2.7v. This patch fixes setup for that pin to have an output voltage of 1.8v to comply with 96boards LS expansion specs. Signed-off-by:
