From: Svyatoslav Ryhel Date: Mon, 6 Apr 2026 07:51:13 +0000 (+0300) Subject: regulator: dt-bindings: regulator-max77620: convert to DT schema X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=881dd6b2ff82c6b0760c2bb5ca1de030608dd7c9;p=thirdparty%2Fkernel%2Flinux.git regulator: dt-bindings: regulator-max77620: convert to DT schema Convert regulator-max77620 devicetree bindings for the MAX77620 PMIC from TXT to YAML format. This patch does not change any functionality; the bindings remain the same.
