gpio: timberdale: Switch to devm_ioremap_resource()
Replace calls to devm_request_mem_region and devm_ioremap with a
direct call to devm_ioremap_resource instead and modify error
handling.
Move the call to platform_get_resource adjacent to the call to
devm_ioremap_resource to make the connection between them more
clear.
A simplified version of the Coccinelle semantic patch that is used to
make this change is as follows:
//<smpl>
@nm@
expression myname;
identifier i;
@@
struct platform_driver i = { .driver = { .name = myname } };
@@
expression dev,res,size,e1,e;
expression nm.myname;
@@
-if (!devm_request_mem_region(dev, res->start, size,
- \(res->name\|dev_name(dev)\|myname\)))
{
- ...
- return ...;
-}
... when != res->start = e1
e =
-devm_ioremap(dev,res->start,size);
+devm_ioremap_resource(dev,res);
if
-(e == NULL)
+(IS_ERR(e))
{
...
-return ...;
+return PTR_ERR(e);
}
//</smpl>
Further, updated error handling by hand as devm_ioremap_resource
gives appropriate error messages, so remove unnecessary error
messages.

gpio: rcar: Add Runtime PM handling for interrupts
The R-Car GPIO driver handles Runtime PM for requested GPIOs only.
When using a GPIO purely as an interrupt source, no Runtime PM handling
is done, and the GPIO module's clock may not be enabled.
To fix this:
- Add .irq_request_resources() and .irq_release_resources() callbacks
to handle Runtime PM when an interrupt is requested,
- Add irq_bus_lock() and sync_unlock() callbacks to handle Runtime PM
when e.g. disabling/enabling an interrupt, or configuring the
interrupt type.

gpio: Propagate all errors in devm_get_gpiod_from_child()
devm_get_gpiod_from_child() tries several property suffixes to find a
GPIO descriptor. If all suffixes fail and no probe deferral has been
detected, it returns the error of the last try.
However, if any but the last try fails with a real error (e.g. -EBUSY),
this error is not propagated, and -ENOENT will be returned.
This confuses drivers that e.g. want to detect if a GPIO is already in
use.
To fix this, change the loop logic to continue on -ENOENT, which
indicates the property was not found and the next suffix should be
tried, and propagate all other detected errors.
