A lot of pinctrl aware gpio chip drivers use the following pattern:
int foo_request_gpio(struct gpio_chip *gc, unsigned gpio)
{
return pinctrl_request_gpio(gc->base + gpio);
}
void foo_request_gpio(struct gpio_chip *gc, unsigned gpio)
{
pinctrl_free_gpio(gc->base + gpio);
}
static struct gpio_chip foo_chip {
...
.request = foo_request_gpio;
.free = foo_request_gpio;
...
};
To prevent this from spreading any further, add and export generic
versions that gpio chip drivers can just use.
* Patch 1 adds the trivial implementations.
* Patch 2 replaces all identical (+/- debug output/comments) versions
in gpio/
* Patch 3/4 modifies drivers that use a boolean for conditional calling
request/free by just not populating the callbacks if the boolean is
false (which is only set at probe)
* Patch 5 replaces all identical version in pinctrl/
Build tested as far as possible (which isn't much when only using
COMPILE_TEST, even when forcing PINCTRL to y).
I don't expect this to break anything, and I triple checked that I did
not introduce any typos, but I can't actually test most of the changed
drivers lacking hardware, therefore RFT.
Patches apply cleanly to 4.3-rc1 as well as linux-gpio/for-next.
Jonas Gorski (5):
gpiolib: provide generic request/free implementations
gpio: replace trivial implementations of request/free with generic one
gpio: gpio-xz: use the generic request/free implementations
gpio: gpio-pl061: use the generic request/free implementations
pinctrl: replace trivial implementations of gpio_chip request/free

Provide generic request/free implementations that pinctrl aware gpio
drivers can use instead of open coding if they use a 1:1 pin to gpio
signal mapping.

Replace all trivial request/free callbacks that do nothing but call into
pinctrl code with the generic versions.

Instead of storing in the chip data whether the chip uses pinctrl and
conditionally call pinctrl_{request,free}_gpio, just don't populate
request/free in that case.
This makes the implementations trivial and the same as the generic
implementations, thus we can just use them.

Hm. Is this really generic? Well I guess of more and more
SoC's get pin controllers in front of their GPIOs then yes. But
for an off-chip GPIO expander this is not really "generic".

Second argument should be named "offset", "gpio" is ambigous
someone could think it's the global GPIO number.
Please collect the various ACKs and I will apply the patch series.
I have another comment which will be more of a discussion and
possible further improvement.

This is way better.
But now this code is starting to multiply in drivers.
Can we think of a way to do this even more generic:
could gpiochip_generic_request() check if the range is
there instead?

I thought about this, and AFAICT this would open a window in which gpio
requests could bypass the pinctrl subsystem, as ranges are only registered
after the gpio chip was registered.
pinctrl_request_gpio() -> pinctrl_get_device_gpio_range() returns -EPROBEDEFER if
it can't find a range for that reason.
To solve this we could introduce a gpiochip_add_with_range(), then we can assign
the generic _request/_free in gpiochip_add in case the callbacks aren't set yet
(and keep the way _request/_free are implemented).
If the gpio-ranges property is used, we could then check for its existence to
assign the callbacks.
So my idea is something like the following. The conversion would be then
chip->request = foo_request;
chip->free = foo_free;
gpiochip_add(chip);
gpiochip_add_pin_range(chip, "foo", 0, 0, npins);
=>
static const struct __initconst pinctrl_gpio_range foo_range = {
.base = 0,
.pinbase = 0,
.npins = npins,
};
gpiochip_add_with_ranges(chip, "foo", &foo_range, 1);
which would be a bit more verbose, but for drivers like pinctrl-cygnus-gpio,
which registers 51(!) pinranges for the same gpio chip, it would mean quite a
bit of code reduction.

Hm! That sounds like a good idea. Alexandre, what do you think?

Neato.

Now we're talking.
Are you interested in doing this refactoring? It'd be awesome.
(Do it on top of this series though, so we can merge this first.)
