[PATCH] clk: mmp2: avoid disabling the SP clock when unused

2019-01-16 Thread Lubomir Rintel
There could be vital functionality running on the SP PJ1 core it can not be restarted just by turning the clock back on. On the OLPC laptop, the keyboard controller code runs there. It wouldn't be possible to load the driver for it as a module if the clock is disabled on boot. Cc: sta...@vger.ker
