[PATCH v2 2/4] ARM: sti: stih407-family: Provide Clock Domain information

From: Lee Jones
Date: Wed Feb 18 2015 - 11:15:41 EST


Certain clocks should not be turned of by clk_disable_unused. Until
now we have been using the kernel command-line of the same name to
prevent common clk from turning off all clocks without a reference,
as this would ensure hardware lockup. This patch lists each clock
which need to stay on to prevent the aforementioned issue from
arising.
