It is, sorry, that was the board that prompted the series.

Interestingly without MCPM I then get:

drivers/built-in.o: In function `bl_enter_powerdown':
/home/andreas/linux/drivers/cpuidle/cpuidle-big_little.c:134: undefined
reference to `mcpm_cpu_powered_up'
drivers/built-in.o: In function `bl_powerdown_finisher':
/home/andreas/linux/drivers/cpuidle/cpuidle-big_little.c:104: undefined
reference to `mcpm_set_entry_vector'
/home/andreas/linux/drivers/cpuidle/cpuidle-big_little.c:111: undefined
reference to `mcpm_cpu_suspend'
Makefile:885: recipe for target 'vmlinux' failed
make: *** [vmlinux] Error 1

ARM_BIG_LITTLE_CPUIDLE seems to be lacking a dependency on MCPM.

Together they resolved the issue, thanks!
