Subject: [PATCH] clk: rockchip: mark pclk_uart2 as critical on rk3328
Date: Wed,  8 Jul 2020 16:45:28 +0200	[thread overview]
Message-ID: <20200708144528.20465-1-jbx6244@gmail.com> (raw)

The rk3328 uart2 port is used as boot console and to debug.
During the boot pclk_uart2 is disabled by a clk_disable_unused
initcall. Fix the uart2 function by marking pclk_uart2
as critical on rk3328. Also add sclk_uart2 as that is needed
for the same DT node.
