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.
