Subject: [PATCH] clk: sprd: don't gate uart console clock
Date: Tue, 31 Mar 2020 18:45:32 +0800 [thread overview]
Message-ID: <20200331104532.12698-1-chunyan.zhang@unisoc.com> (raw)
Don't gate uart1_eb which provides console clock, gating that clock would
make serial stop working if serial driver didn't enable that explicitly.
