      ARM: pxa: add memory resource to SA1100 RTC device · 2c4fabec
      由 Rob Herring 提交于 
      The drivers for the SA1100 and PXA RTCs are now mutually exclusive, so
add the memory resource for the sa1100-rtc device. Since the memory
resource is already present in the pxa_rtc_resources, that makes
sa1100_rtc_resources and pxa_rtc_resources equivalent, so use
pxa_rtc_resources for both devices and remove the duplicate
sa1100_rtc_resources.

      rtc: pxa: convert to use shared sa1100 functions · 3cdf4ad9
      由 Rob Herring 提交于 
      Currently, the rtc-sa1100 and rtc-pxa drivers co-exist as rtc-pxa has a
superset of functionality. Having 2 drivers sharing the same memory
resource is not allowed by the driver model if resources are properly
declared. This problem was avoided by not adding memory resources to the
SA1100 RTC driver, but that prevents clean-up of the SA1100 driver.

This commit converts the PXA RTC to use the exported SA1100 RTC
functions. Now the sa1100-rtc and pxa-rtc devices are mutually
exclusive, so we must remove the sa1100-rtc from pxa27x and pxa3xx.

      ARM: kill off set_irq_flags usage · e8d36d5d
      由 Rob Herring 提交于 
      set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:

IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN

For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed. There appears to be a great deal of
blind copy and paste of this code.

      ARM: appropriate __init annotation for const data · 19c233b7
      由 Nicolas Pitre 提交于 
      Init data marked const should be annotated with __initconst for
correctness and not __initdata.  In some cases the array gathering
references to that data has to be marked const as well. This fixes
LTO builds that otherwise fail with section mismatch errors.

      ARM: pxa: transition to dmaengine phase 1 · 4be0856f
      由 Robert Jarzmik 提交于 
      In order to slowly transition pxa to dmaengine, the legacy code will now
rely on dmaengine to request a channel.

This implies that PXA architecture selects DMADEVICES and PXA_DMA,
which is not pretty. Yet it enables PXA drivers to be ported one by one,
with part of them using dmaengine, and the other part using the legacy
code.

      ARM: pxa: pxa_cplds: add lubbock and mainstone IO · aa8d6b73
      由 Robert Jarzmik 提交于 
      Historically, this support was in arch/arm/mach-pxa/lubbock.c and
arch/arm/mach-pxa/mainstone.c. When gpio-pxa was moved to drivers/pxa,
it became a driver, and its initialization and probing happened at
postcore initcall. The lubbock code used to install the chained lubbock
interrupt handler at init_irq() time.

The consequence of the gpio-pxa change is that the installed chained irq
handler lubbock_irq_handler() was overwritten in pxa_gpio_probe(_dt)(),
removing :
 - the handler
 - the falling edge detection setting of GPIO0, which revealed the
   interrupt request from the lubbock IO board.

As a fix, move the gpio0 chained handler setup to a place where we have
the guarantee that pxa_gpio_probe() was called before, so that lubbock
handler becomes the true IRQ chained handler of GPIO0, demuxing the
lubbock IO board interrupts.

This patch moves all that handling to a mfd driver. It's only purpose
for the time being is the interrupt handling, but in the future it
should encompass all the motherboard CPLDs handling :
 - leds
 - switches
 - hexleds

The same logic applies to mainstone board.

      I recently did a rework of the smc91x driver and did some build-testing
by compiling hundreds of randconfig kernels. Unfortunately, my script
was wrong and did not actually test the configurations that mattered,
so I introduced stupid typos in almost every file I touched.

I fixed my script now, built all configurations that actually matter
and fixed all the typos, this is the result.
