From: Chen-Yu Tsai Date: Sat, 12 Jul 2025 07:40:17 +0000 (+0800) Subject: dt-bindings: power: Add A523 PPU and PCK600 power controllers X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=f99d4fccd2185176baf4ecac9a49d280fc62b953;p=thirdparty%2Flinux.git dt-bindings: power: Add A523 PPU and PCK600 power controllers The A523 PPU is likely the same kind of hardware seen on previous SoCs. The A523 PCK600, as the name suggests, is likely a customized version of ARM's PCK-600 power controller. Comparing the BSP driver against ARM's PPU datasheet shows that the basic registers line up, but Allwinner's hardware has some additional delay controls in the reserved register range. As such it is likely not fully compatible with the standard ARM version. Document A523 PPU and PCK600 compatibles. Also reorder the compatible string entries so they are grouped and ordered by family first, then by SoC model.
