Hi,

This series addresses the power management for SAMA7G5 and also updates
the master clock prescaller and master clock divider drivers to accommodate
the requests at [1].

The power management part is implemented by adding
save_context()/restore_context() on each clock driver (patch 1/6). Since
the PM part is necessary only for backup mode (supported on SAMA5D2 and
SAMA7G5) the pmc.c has been adapted to call the
save_context()/restore_context() only on switches to/from backup mode
(patch 2/6).

Patch 3/6 adds the securam clock on SAMA7G5. This is necessary for
backup mode of SAMA7G5.

Patch 4/6 adds registers definitions for the new master clocks (MCK1..4) of
SAMA7G5 and adapt the clk-master.c. The defines exported in
include/linux/clk/at91_pmc.h will be also used by platform specific PM
code.

Patch 5/6 adpat the master clock divider and master clock prescaller
to address the requests at [1].

Patch 6/6 clean up a bit the code in clk-master as suggested by Nicolas.

Thank you,
Claudiu Beznea

Hi Stephen,

Please ignore the DVFS patch in this series
(clk: at91: clk-master: update for dvfs) as I have some updates to it. I'll
introduce them in the next version.

Thank you,
Claudiu Beznea
