However, the PMIC can output up to 3.3V on that regulator by skipping the 2.6V and 2.9V steps. Fix the ranges to read and set the proper voltages. Fixes: 13d57e64352a ("regulator: axp20x: Use linear voltage ranges for AXP20X LDO4") Signed-off-by: Maxime Ripard --- Hi Mark, This patch fixes a commit merged into 4.6-rc1, so it should probably go in the next -rc release.
