From eb2838790ba71c686b7e9f0df3d1e99caad5ff5f Mon Sep 17 00:00:00 2001 From: Marijn Suijten Date: Mon, 20 Jun 2022 23:12:12 +0200 Subject: [PATCH] arm64: dts: qcom: sdm845-akatsuki: Round down l22a regulator voltage [ Upstream commit 4148a9eeb15152865d60b0913d96beb7ca166f9a ] 2700000 is not a multiple of pmic4_pldo's step size of 8000 (with base voltage 1664000), resulting in pm8998-rpmh-regulators not probing. Just as we did with MSM8998's Sony Yoshino Poplar [1], round the voltages down to err on the cautious side and leave a comment in place to document this discrepancy wrt downstream sources.
