#61149 — Bug#900799: linux-image-arm64: dts: rockchip: correct voltage selector Firefly-RK3399

Package: linux-image-arm64
Version: 4.16.12-1
Severity: normal
Tags: patch

Please, add this patch to the Debian kernel patches until it is added
upstream. Cf.
https://lkml.org/lkml/2018/6/4/781

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.

-------- Forwarded Message --------

applied for 4.19.

I've amended your commit message with the info from your reply about
the vendor kernel using the same value and added an appropriate Fixes
tag to possibly get it merged into stable.


Thanks
Heiko
