      gpio: defer probe if pinctrl cannot be found · 28355f81
      Tomeu Vizoso authored 
      When an OF node has a pin range for its GPIOs, return -EPROBE_DEFER if
the pin controller isn't available.

Otherwise, the GPIO range wouldn't be set at all unless the pin
controller probed always before the GPIO chip.

With this change, the probe of the GPIO chip will be deferred and will
be retried at a later point, hopefully once the pin controller has been
registered and probed already.

      gpio: kill off set_irq_flags usage · 23393d49
      Rob Herring authored 
      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 as most platforms don't use probing.
There appears to be a great deal of blind copy and paste of this code.

      gpio/davinci: Fix race in installing chained irq handler · bdac2b6d
      Thomas Gleixner authored 
      Fix a race where a pending interrupt could be received and the handler
called before the handler's data has been setup, by converting to
irq_set_chained_handler_and_data().
    
Search and conversion was done with coccinelle.

      gpio/davinci: Avoid redundant lookup of irq_data · 1765d671
      Thomas Gleixner authored 
      It's pretty silly to do

     void *cd = irq_get_chip_data(irq_data->irq);

because that results in cd = irq_data->chip_data, but goes through a
redundant lookup of the irq_data. Use irq_data directly.

      gpio/sa1100: Prepare sa1100_gpio_handler for irq argument removal · 2951a799
      Thomas Gleixner authored 
      The irq argument of most interrupt flow handlers is unused or merily
used instead of a local variable. The handlers which need the irq
argument can retrieve the irq number from the irq descriptor.

Search and update was done with coccinelle and the invaluable help of
Julia Lawall.
