The Kconfig currently controlling compilation of this code is:
drivers/gpio/Kconfig:config GPIO_TIMBERDALE
drivers/gpio/Kconfig: bool "Support for timberdale GPIO IP"
...meaning that it currently is not being built as a module by anyone.
Lets remove the modular code that is essentially orphaned, so that
when reading the driver there is no doubt it is builtin-only.
We explicitly disallow a driver unbind, since that doesn't have a
sensible use case anyway, and it allows us to drop the ".remove"
code for non-modular drivers.
Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.
We also delete the MODULE_LICENSE tag etc. since all that information
was (or is now) contained at the top of the file in the comments.

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.

The name .dev in a struct is normally reserved for a struct device
that is let us say a superclass to the thing described by the struct.
struct gpio_chip stands out by confusingly using a struct device *dev
to point to the parent device (such as a platform_device) that
represents the hardware. As we want to give gpio_chip:s real devices,
this is not working. We need to rename this member to parent.
This was done by two coccinelle scripts, I guess it is possible to
combine them into one, but I don't know such stuff. They look like
this:
@@
struct gpio_chip *var;
@@
-var->dev
+var->parent
and:
@@
struct gpio_chip var;
@@
-var.dev
+var.parent
and:
@@
struct bgpio_chip *var;
@@
-var->gc.dev
+var->gc.parent
Plus a few instances of bgpio that I couldn't figure out how
to teach Coccinelle to rewrite.
This patch hits all over the place, but I *strongly* prefer this
solution to any piecemal approaches that just exercise patch
mechanics all over the place. It mainly hits drivers/gpio and
drivers/pinctrl which is my own backyard anyway.

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.

scripts around it. Thanks to Julia for her help!

set_irq_flags is ARM specific with custom flags which have genirq
equivalents. Convert drivers to use the genirq interfaces directly, so we
can kill off set_irq_flags. The translation of flags is as follows:
IRQF_VALID -> !IRQ_NOREQUEST
IRQF_PROBE -> !IRQ_NOPROBE
IRQF_NOAUTOEN -> IRQ_NOAUTOEN
For IRQs managed by an irqdomain, the irqdomain core code handles clearing
and setting IRQ_NOREQUEST already, so there is no need to do this in
.map() functions and we can simply remove the set_irq_flags calls. Some
users also modify IRQ_NOPROBE and this has been maintained although it
is not clear that is really needed as most platforms don't use probing.
There appears to be a great deal of blind copy and paste of this code.

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.

Switch all users of irq_set_chip_and_handler_name() to simply
use irq_set_chip_and_handler(), all just provide a boilerplate
name like "demux" or "mux" - a fact which is anyway obvious
from the hwirq number from the irqdomain now present in e.g.
/proc/interrupts.
