From 00460e3358bc1f89732312aeaaa01c143adf012d Mon Sep 17 00:00:00 2001 From: Tushar Nimkar Date: Tue, 23 Feb 2021 11:32:38 +0530 Subject: [PATCH] dt-bindings: msm: rpmh-master-stats: Update reg as optional property This change updates reg as optional property so that same driver can be used for RPM based targets where profiling unit register is not present. This enables rpmh_master_stats driver to read different subsystem master stats data from SMEM for RPM based targets.
