It's not appropriate to use 'ARM:' as subject prefix any more, since
clock drivers had been moved to drivers/clk.

I applied patch 6 ~ 9 with updating the subject prefix as below.

clk: imx: vf610: add suspend/resume support
clk: imx: vf610: add WKPU unit
clk: imx: vf610: leave DDR clock on
clk: imx: clk-gate2: allow custom gate configuration
