From a19a209ee420f95626451034ba287c33d0d64ce0 Mon Sep 17 00:00:00 2001 From: Krzysztof Kozlowski Date: Sat, 29 Jun 2019 13:47:38 +0200 Subject: [PATCH] ARM: dts: exynos: Adjust buck[78] regulators to supported values on Odroid XU3 family The datasheet of S2MPS11 PMIC is slightly non-consistent in buck[78] voltage regulators values. 1. The voltage tables for configuring their registers mention range of voltages: 0.750 V to 3.55 V, 2. The constrains in electrical specifications say output voltage range to be different (buck7: 1.2 V to 1.5 V, buck8: 1.8 V to 2.1 V). Adjust the ranges to match the electrical specifications to stay on the safe side. Also change the name of regulators to match reality. Anyway these regulators stay at default value so this should not have effect.
