From 8e7a7ffec6711069e2c0032574d93f75cf0ab454 Mon Sep 17 00:00:00 2001 From: Roger Quadros Date: Wed, 18 Sep 2024 16:49:21 +0300 Subject: [PATCH] mux: mmio: Support "reg-mux" compatible With "reg-mux" compatible the driver no longer expects the parent device to be a syscon type. It uses it's own regmux.
