Subject: arm64: dts: rockchip: correct voltage selector on Firefly-RK3399
|
|
Bug-Debian: https://bugs.debian.org/900799
|
|
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/mmind/linux-rockchip.git/patch/?id=710e8c4a54be82ee8a97324e7b4330bf191e08bf
|
|
|
|
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
|
|
and also matches the value used in the vendor kernel.
