[PATCH 1/1] arm64: dts: rockchip: correct voltage selector Firefly-RK3399

From: Heinrich Schuchardt
Date: Mon Jun 04 2018 - 13:16:21 EST


Without this patch the Firefly-RK3399 board boot process hangs after these
lines:

fan53555-regulator 0-0040: FAN53555 Option[8] Rev[1] Detected!
fan53555-reg: supplied by vcc_sys
vcc1v8_s3: supplied by vcc_1v8

Blacklisting driver fan53555 allows booting.

The device tree uses a value of fcs,suspend-voltage-selector different to
any other board.

Changing this setting to the usual value is sufficient to enable booting.
