gpio: stmpe: enforce device tree only mode

2015-01-20T10:03:22+00:00

Require that device tree be used with STMPE (all platforms use this)
and enforce OF_GPIO, then delete the platform data.

gpio: stmpe: add verbose debug code

2014-10-02T14:06:59+00:00

To troubleshoot the STMPE GPIO driver, some more detailed
debug information giving the exact info on how each pin is
used will be helpful.

gpio: stmpe: fix up interrupt enable logic

2014-10-02T07:19:22+00:00

The STMPE driver assumes that the passed in IRQ type is
for rising or falling IRQs, not both, even though the
hardware actually supports this perfectly well. Likewise
the check for level IRQs is done against just high or low
level types, not for the case where it is combined with
other IRQs.

gpio: handle also nested irqchips in the chained handler set-up

2014-09-26T12:39:08+00:00

To unify how we connect cascaded IRQ chips to parent IRQs, if
NULL us passed as handler to the gpiochip_set_chained_irqchip()
function, assume the chips is nested rather than chained, and
we still get the parent set up correctly by way of this function
call.

Alter the drivers for tc3589x and stmpe to use this to set up
their chained handlers as a demonstration of the usage.

gpio: stmpe: switch to use gpiolib irqchip helpers

2014-06-19T07:31:16+00:00

This switches the STMPE driver to use the gpiolib irqchip
helpers.

mfd: stmpe: root out static GPIO and IRQ assignments

2014-05-23T08:41:01+00:00

The only platform using the STMPE expander now boots from
device tree using all-dynamic GPIO and IRQ number assignments, so
remove the mechanism to pass this from the device tree entirely.

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: stmpe: drop references to "virtual" IRQ, fix bug

2013-10-16T07:59:53+00:00

Rename the argument "virq" to just "irq", this IRQ isn't any
more "virtual" than any other Linux IRQ number, we use "hwirq"
for the actual hw-numbers, "virq" is just bogus.

When doing this I see that the hwirq argument is used
for mapping rather than the Linux IRQ in the map function.
This doesn't look right. Use the Linux IRQ instead.

I cannot test this patch so I don't know if the mapping change
is correct, however since absolutely every other driver does
it the other way around this doesn't look sound at all. Please
help out with review.

gpio: stmpe: Staticize non-exported symbols

2013-05-30T17:20:22+00:00

Both stmpe_gpio_irq_map() and stmpe_gpio_irq_unmap() are not referenced
outside of this file, make them static.
