It's quite common for PM domains to use PM clocks. Typically from SOC
specific code, the per device PM clock list is created and
pm_clk_suspend|resume() are invoked to handle clock gating/ungating.
A step towards consolidation is to integrate PM clock support into
genpd, which is what this patch

to be the cause of these aborts (possibly because the secure f/w was not
