Actually, I guess it is:
Changes in v2:
- Rebase on the at91-3.20-cleanup branch
- Recover the verify clock condition, only for suspend to memory.
- Collect ACK from Alexandre
- Add the macro for PM mode
Changes in v3
- Sylvain splits the patch in two
- Add handling if no sram allocated for PM
- Retain the STANDBY and SUSPEND_MEM select in at91_pm_enter.
Changes in v4:
- Clear unused state argument in at91_pm_verify_clocks()
- Remove pr_info("AT91:... slow_clock ? ..") in patch 07/13.
(I prefer the reverse order, but, details)
Sylvain
