Subject: [RESEND PATCH 0/5] clk: at91: updates for power management and dvfs

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 1/5). 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 2/5).

Patch 3/5 adds the securam clock on SAMA7G5. This is necessary for
backup mode of SAMA7G5.

Patch 4/5 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 5/5 adpat the master clock divider and master clock prescaller
to address the requests at [1].

Thank you,
Claudiu Beznea
