From 073a01e8d7c23b3efb59a3d4c20aa546f9ec29a9 Mon Sep 17 00:00:00 2001 From: Peng Fan Date: Fri, 1 Nov 2019 10:16:19 +0000 Subject: clk: imx: clk-composite-8m: add lock to gate/mux There is a lock to divider in the composite driver, but that's not enough. lock to gate/mux are also needed to provide exclusive access to the register.
