gpio: adnp: switch to use irqchip helpers

2014-09-02T08:44:01+00:00

This switches the ADNP GPIO driver to use the gpiolib
irqchip helpers. Also do some random refactoring to make it
look like most other GPIO drivers.

gpio: switch drivers to use new callback

2014-03-18T08:28:30+00:00

This switches all GPIO and pin control drivers with irqchips
that were using .startup() and .shutdown() callbacks to lock
GPIO lines for IRQ usage over to using the .request_resources()
and .release_resources() callbacks just introduced into the
irqchip vtable.

gpio: lock adnp IRQs when enabling them

2013-12-04T13:46:19+00:00

This uses the new API for tagging GPIO lines as in use by
IRQs. This enforces a few semantic checks on how the underlying
GPIO line is used.

Only compile tested on the lpc32xx.

ChangeLog v2->v3:
- Switch to using the startup()/shutdown() callbacks again.
  Still satisfy the mask/unmask semantics.
ChangeLog v1->v2:
- Use the .enable() callback from the irq_chip
- Call .unmask() from the .enable() callback to satisfy semantics.

gpio/pinctrl: make gpio_chip members typed boolean

2013-12-04T13:42:46+00:00

This switches the two members of struct gpio_chip that were
defined as unsigned foo:1 to bool, because that is indeed what
they are. Switch all users in the gpio and pinctrl subsystems
to assign these values with true/false instead of 0/1. The
users outside these subsystems will survive since true/false
is 1/0, atleast we set some kind of more strict typing example.

gpio: adnp: rename "virq" to "child_irq"

2013-10-16T07:59:10+00:00

This variable is confusingly named, the different Linux IRQs
aren't any more virtual than any other Linux IRQ. Give it a
non-misleading name.

gpio: adnp: Remove redundant of_match_ptr

2013-10-02T10:42:38+00:00

The data structure of_match_ptr() protects is always compiled in.
Hence of_match_ptr() is not needed.

gpio: adnp: Fix segfault if request_threaded_irq fails

2013-08-16T14:53:16+00:00

In case request_threaded_irq inside adnp_irq_setup fails, the driver
segfaults. This is because irq_domain_remove is called twice with
the same pointer. First time in adnp_irq_setup and then a second time
after leaving adnp_irq_setup in the error path of adnp_i2c_probe
inside adnp_teardown.
This fixes this by removing the call to irq_domain_remove from
adnp_irq_setup.

gpio: remove use of __devexit

2012-11-28T19:39:59+00:00

CONFIG_HOTPLUG is going away as an option so __devexit is no
longer needed.
