From: Gray Huang Date: Wed, 25 Mar 2026 05:46:09 +0000 (+0800) Subject: arm64: dts: rockchip: Add PMIC support for Khadas Edge 2L X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7cd8b37304be367106a02d4d902294e9bea3f45d;p=thirdparty%2Fkernel%2Flinux.git arm64: dts: rockchip: Add PMIC support for Khadas Edge 2L Add RK806 PMIC support for the Khadas Edge 2L board. Assign the corresponding PMIC regulators (vdd_cpu_lit_s0 and vdd_cpu_big_s0) to the little and big CPU clusters to enable proper power management and CPU frequency scaling.
