Hi Nicolas,
This version is rebased on the branch: at91-3.20-cleanup of the repository
git://git.kernel.org/pub/scm/linux/kernel/git/nferre/linux-at91.git
It is purpose to clean up the PM code, includes the patches from Peter Rosin
and Sylvain Rochet.
Since verifying the USB clock and USB PLL disabling before suspending to memory,
it aslo depends on the following patch serials from Sylvain:
[PATCHv6 0/5] USB: gadget: atmel_usba_udc: Driver improvements
[PATCHv7 0/6] USB: host: Atmel OHCI and EHCI drivers improvements
Removes CONFIG_AT91_SLOW_CLOCK config item to simply the PM config,
The suspend to standby mode uses the same sram function as the suspend to
memory mode.
Remove some unused code.
Alexandr & Sylvain, Thank you very much for so many feedbacks.
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
