From f8327147e586246ef2c2941cbb0ab5fd0f1531d0 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 4 Jun 2018 19:15:23 +0200 Subject: [PATCH] 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.
