From 6dda12150785665ddd1059d53aa22bf902bfe4aa Mon Sep 17 00:00:00 2001 From: Andre Werner <andre.werner@systec-electronic.com> Date: Mon, 22 Nov 2021 15:40:17 +0100 Subject: [PATCH] linux: regulator: pca9450.h: Correct register masks for LDOs
Within the defines of the register masks for LDO3 and LDO4, the most significant bit was missing. The datasheet said the range is 4:0 bits. Thus, the output voltage cannot be set above 1.7V for each.
