While working on suspend-to-disk functionality on TI dra7-evm (DRA7xx SoC)
i've found that the most common problem I have to dial with is absence
of corresponding PM callbacks in drivers and, in particular, noirq callbacks.
So, I've fixed one driver first
commit 6248015d6867 "ARM: omap-device: add missed callback for suspend-to-disk"
but then found another one which need to be fixed too (omap_l3_noc.c).
At this moment I decided to make my life easier and added new macro
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS using the same approach as for the existing
SET_SYSTEM_SLEEP_PM_OPS macro.
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS: defined for CONFIG_PM_SLEEP and
assigns ->suspend_noirq, ->freeze_noirq and ->poweroff_noirq to the same
function. Vice versa happens for ->resume_noirq, ->thaw_noirq and
->restore_noirq.
Further two patches reuse this newly introduced macro.
SET_NOIRQ_SYSTEM_SLEEP_PM_OPS, defined for CONFIG_PM_SLEEP, will
point ->suspend_noirq, ->freeze_noirq and ->poweroff_noirq to the same
function. Vice versa happens for ->resume_noirq, ->thaw_noirq and
->restore_noirq.
