pinctrl: Use device_get_match_data()

2023-10-30T13:50:42+00:00

Use preferred device_get_match_data() instead of of_match_device() to
get the driver match data. With this, adjust the includes to explicitly
include the correct headers.

pinctrl: nomadik: abx500: Convert to platform remove callback returning void

2023-10-10T13:38:12+00:00

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.

To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new(), which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Merge tag 'pinctrl-v6.3-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2023-02-22T19:05:56+00:00

Pull pin control updates from Linus Walleij:
 "Nothing special, notably a lot of new Qualcomm hardware is supported,
  a RISC-V reference SoC and then some cleanups both in code and device
  tree bindings.

  Core changes:

   - Add PINCTRL_PINFUNCTION() macro and use it in several drivers

  New drivers:

   - New driver for the StarFive JH7110 SoC "sys" and "aon" (always-on)
     pin controllers. (RISC-V.)

   - New subdriver for the Qualcomm QDU1000/QRU1000 SoC pin controller

   - New subdrivers for the Qualcomm SM8550 SoC and LPASS pin
     controllers

   - New subdriver for the Qualcomm SA8775P SoC pin controller

   - New subdriver for the Qualcomm IPQ5332 SoC pin controller

   - New (trivial) support for Qualcomm PM8550 and PMR735D PMIC pin
     control

   - New subdriver for the Mediatek MT7981 SoC pin controller

  Improvements:

   - Several cleanups and refactorings to the Intel drivers

   - Add 4KOhm bias support to the Intel driver

   - Use the NOIRQ_SYSTEM_SLEEP_PM_OPS for the AT91 driver

   - Support general purpose clocks in the Qualcomm MSM8226 SoC

   - Several conversions to use the new I2C .probe_new() call

   - Massive clean-up of the Qualcomm Device Tree YAML schemas

   - Add VIN[45] pins, groups and functions to the Renesas r8a77950 SoC
     driver"

pinctrl: nomadik: Add missing header(s)

2023-01-04T01:36:47+00:00

Do not imply that some of the generic headers may be always included.
Instead, include explicitly what we are direct user of.

While at it, sort headers alphabetically.

pinctrl: nomadik: remove dead code after DB8540 pinctrl removal

2022-09-19T07:35:57+00:00

Commit b6d09f780761 ("pinctrl: nomadik: Drop U8540/9540 support") removes
the DB8540 pin controller driver and its config PINCTRL_DB8540.

There is some code left-over in the generic nomadik pinctrl driver, i.e.,
drivers/pinctrl/nomadik/pinctrl-nomadik.{ch}, that is still around for the
removed DB8540 pin controller driver.

Remove this remaining dead code.

This issue was discovered with ./scripts/checkkconfigsymbols.py.

pinctrl: nomadik: Dereference gpio_chip properly

2022-09-19T07:02:56+00:00

The irq data passed to irc_chip handlers i the struct gpio_chip
and nothing else. We are just lucky that the nomadik chip
pointer is first in the struct. Use the proper dereferencing
and helpers.
