      ARM: at91: AIC and GPIO IRQ device tree initialization · 8014d6f4
      由 Nicolas Ferre 提交于 
      Both AIC and GPIO controllers are now using the standard of_irq_init()
function to initialize IRQs in case of DT use.
The DT specific initialization functions are now separated from the
non-DT case and are now using "linear" irq domains.
The .map() irqdomain operation is responsible for positioning the IRQ
handlers. In AIC case, the Linux IRQ number is directly programmed in
the hardware to avoid an additional reverse mapping operation.
The AIC position its irq domain as the "default" irq domain.

For DT case, the priority is not yet filled in the SMR. It will be the
subject of another patch.

      ARM: restart: at91: use new restart hook · 1b2073e7
      由 Russell King 提交于 
      Rather than using a private function pointer, use the existing
arm_pm_restart function pointer instead.  We no longer need to enable
the I-cache in at91sam9_alt_reset() as the caches will now be on when
this function is called.

Update the function names to use the 'restart' terminology rather than
the 'reboot' terminology.

      [ARM] 4739/1: at91sam9263: make gpio bank C and D irqs work · e83aff58
      由 David Brownell 提交于 
      On the at91sam9263, IRQs for GPIO banks C and D don't currently work.
This is because banks C, D, and E share one clock and toplevel IRQ, but
the AT91 code setting up and handling GPIO IRQs expects no sharing.
This patch:

 - Fixes GPIO IRQ setup and handling to cope with GPIO banks that are
   shared like on sam9263 chips, by setting up a list of those banks
   and making the IRQ dispatching logic scan that list.

 - Precomputes the address of each bank's registers, saving it with
   other per-bank data so that it no longer needs to be constantly
   recomputed during IRQs and other GPIO operations.  That shrinks
   hot-path code, while helping the GPIO bank irq updates.

 - Fixes a minor bug where IRQ_TYPE_NONE was wrongly rejected (it just
   means "use the default", which is "both edges" here).

      [ARM] 3605/1: AT91RM9200 Power Management · 907d6deb
      由 Andrew Victor 提交于 
      Patch from Andrew Victor

This patch adds the core Power Management support for the AT91RM9200
processor.  It will support suspend-to-RAM and standby modes.

The suspend-to-RAM functionality is not 100% complete.  The code that
needs to be execute from the internal SRAM to restore the system is
outstanding.  For now we just fall through to Standby mode.

The AT91-specific at91_suspend_entering_slow_clock() function will
eventually be replaced by clk_must_disable() once that functionality is
added to mainline clock API.

Patch from David Brownell.
