From 22f86fab644b0c35421a728e4e30286d6f5e5a20 Mon Sep 17 00:00:00 2001 From: Ulf Hansson Date: Mon, 3 Jul 2023 16:09:41 +0200 Subject: soc: amlogic: Move power-domain drivers to the genpd dir To simplify with maintenance let's move the amlogic power-domain drivers to the new genpd directory. Going forward, patches are intended to be managed through a separate git tree, according to MAINTAINERS.
