commit 8ba92cf5 ("arm64: dts: actions: s700: Add Clock Management Unit") breaks the UART on Cubieboard7-lite (based on S700 SoC), This is due to the fact that generic clk routine clk_disable_unused() disables the gate clks, and that in turns disables OWL UART (but UART driver never enables it). To prove this theory, Andre suggested to use "clk_ignore_unused" in kernel commnd line and it worked (Kernel happily lands into RAMFS world :)). This commit fix this up by adding clk_prepare_enable(). Fixes: 8ba92cf5 ("arm64: dts: actions: s700: Add Clock Management Unit") Signed-off-by:
