pinctrl: sx150x: handle missing 'advanced' reg in sx1504 and sx1505

This fixes a problem where sx150x_regmap_reg_width() returns 8 for the
data register (reg 0) for sx1504 where it should return 4, and return
a correct 8 for sx1505 but for the wrong reason (both chips lack the
'advanced' register). This is not a real problem, since nothing depends
on the function returning 4 or 8, and certainly not if it is returning
8 for the wrong reason. But fix this to avoid nasty surprises down the
line.

pinctrl: bcm2835: switch to GPIOLIB_IRQCHIP

It should be possible to use the GPIOLIB_IRQCHIP helper
library with the BCM2835 driver since it is a pretty straight
forward cascaded irqchip.

The only difference from other drivers is that the BCM2835
has several banks for a single gpiochip, and each bank has
a separate IRQ line. Instead of creating one gpiochip per
bank, a single gpiochip covers all banks GPIO lines. This
makes it necessary to resolve the bank ID in the IRQ
handler.

The GPIOLIB_IRQCHIP allows several IRQs to be cascaded off
the same gpiochip by calling gpiochip_set_chained_irqchip()
repeatedly, but we have been a bit short on examples
for how this should be handled in practice, so this is intended
as an example of how this can be achieved.

The old code did not model the chip as a chained interrupt
handler, but this patch also rectifies that situation.

Fix this by actually reading the hardware registers and returning

setting .is_generic = true in pinconf_ops.

Also remove the cached config value. The behavior of this was never

None of the Kconfigs for any of these drivers are tristate, meaning
that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get the exact same change, so they are handled in batch.

Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
(5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags and (6)
drop ".remove" code and prevent sysfs unbind attempts to call ".remove".

Once this is done, the shared remove function in wmt.[ch] is no longer
used and hence it is removed as well.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We also delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

registers on the chip itself and atomicity of various regmap operations

pinctrl-sx150x: Replace sx150x_*_cfg by means of regmap API

The difference between 8 and 16 pin GPIO expanders can be accomodated by
the means of regmap API without resorting to using driver-specific
read/write accessors. This change, IMHO, brings the following benefits:

- Replaces driver's idiosyncratic way of dealing with
  mult-register fields with regmap API, which, hopefuly,
  makes the code a bit easier for a new reader to understand

- Removes various multi-read for-loop register read logic
  from various places in the code and puts it in a signle
  place

- Removes ad-hoc IRQ register caching code in
  sx150x_irq_bus_sync_unlock, since that functionality is
  provided by regmap

Besided aforementioned benefits this change also implements necessary
RegSense byte swap necessary for SX1503 and SX1506 variants of the chip.

pinctrl: sunxi: make bool drivers explicitly non-modular

None of the Kconfigs for any of these drivers are tristate,
meaning that they currently are not being built as a module by anyone.

Lets remove the modular code that is essentially orphaned, so that
when reading the drivers there is no doubt they are builtin-only.  All
drivers get essentially the same change, so they are handled in batch.

Changes are (1) use builtin_platform_driver, (2) use init.h header
(3) delete module_exit related code, (4) delete MODULE_DEVICE_TABLE,
and (5) delete MODULE_LICENCE/MODULE_AUTHOR and associated tags.

Since module_platform_driver() uses the same init level priority as
builtin_platform_driver() the init ordering remains unchanged with
this commit.

Also note that MODULE_DEVICE_TABLE is a no-op for non-modular code.

We do delete the MODULE_LICENSE etc. tags since all that information
is already contained at the top of each file in the comments.

pinctrl: Add SX150X GPIO Extender Pinctrl Driver

Since the I2C sx150x GPIO expander driver uses platform_data to manage
the pins configurations, rewrite the driver as a pinctrl driver using
pinconf to get/set pin configurations from DT or debugfs.

The pinctrl driver is functionnally equivalent as the gpio-only driver
and can use DT for pinconf. The platform_data confirmation is dropped.

This patchset removed the gpio-only driver and selects the Pinctrl driver
config instead. This patchset also migrates the gpio dt-bindings to pinctrl
and add the pinctrl optional properties.

The driver was tested with a SX1509 device on a BeagleBone black with
interrupt support and on an X86_64 machine over an I2C to USB converter.

This is a fixed version that builds and runs on non-OF platforms and on
arm based OF. The GPIO version is removed and the bindings are also moved
to the pinctrl bindings.

Changes since v2
 - rebased on v4.9-rc1
 - removed MODULE_DEVICE_TABLE as in upstream bb411e771b0e
   ("gpio: sx150x: fix implicit assumption module.h is present")

Changes since v1
 - Fix Kconfig descriptions on pinctrl and gpio
 - Fix Kconfig dependency
