      ARM: at91: add AIC5 support · c4b68520
      由 Ludovic Desroches 提交于 
      The number of lines of AIC5 has increased from 32 to 128. Due to this
increase, a source select register has been introduced for the interrupt
line selection. Moreover, register mapping has been changed. For that reasons,
we need some dedicated callbacks for AIC5.
Power management is also concerned by these changes. On suspend, we can't get
the whole interrupt mask register as before, we have to read this register 128
times. To reduce this overhead, a snapshot of the whole IMR is maintained.

      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).
