pinctrl: sun5i: Fix a10s pwm1 pinctrl mapping

2015-10-02T11:06:01+00:00

The comment for PG14 mux setting 3 already correctly states that this
muxes PG13 to pwm1, but the text ascociated with it said uart3, fix this.

Note that we use "pwm" rather then "pwm1" to be consistent with pwm0
where the mux setting is also simply called "pwm" and to be consistent
with sun4i/sun7i which do the same.

genirq: Remove irq argument from irq flow handlers

2015-09-16T13:47:51+00:00

Most interrupt flow handlers do not use the irq argument. Those few
which use it can retrieve the irq number from the irq descriptor.

Remove the argument.

Search and replace was done with coccinelle and some extra helper
scripts around it. Thanks to Julia for her help!

pinctrl: sunxi: Use irq_set_chip_handler_name_locked()

2015-09-16T10:42:49+00:00

__irq_set_chip_handler_name_locked() is about to be replaced. Use
irq_set_chip_handler_name_locked() instead.

pinctrl: sunxi: Add custom irq_domain_ops

2015-07-27T12:56:30+00:00

The current interrupt parsing code was working by accident, because the
default was actually parsing the first node of interrupts.

While that was mostly working (and the flags were actually ignored), this
binding has never been documented, and doesn't work with SoCs that have
multiple interrupt banks anyway.

Add a proper interrupt xlate function, that uses the same description than
the GPIOs (  ), that will make things less confusing.

The EINT number will still be used as the hwirq number, but won't be
exposed through the DT.

pinctrl: sunxi: Use common functions to change irq_chip and handler

2015-07-27T12:05:04+00:00

The current code uses some custom variable affectations, while we have
common functions to do exactly that. Move to the common functions.

pinctrl/sunxi: Prepare sunxi_pinctrl_irq_handler for irq argument removal

2015-07-17T19:56:23+00:00

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.

Merge branch 'irq-urgent-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip

2015-07-01T22:19:35+00:00

Pull irq fixes from Thomas Gleixner:
 "This contains:

   - a series of fixes for interrupt drivers to prevent a potential race
     when installing a chained interrupt handler

   - a fix for cpumask pointer misuse

   - a fix for using the wrong interrupt number from struct irq_data

   - removal of unused code and outdated comments

   - a few new helper functions which allow us to cleanup the interrupt
     handling code further in 4.3

   I decided against doing the cleanup at the end of this merge window
   and rather do the preparatory steps for 4.3, so we can run the final
   ABI change at the end of the 4.3 merge window with less risk"
