pinctrl: meson: Fix typo in device table macro

2025-08-18T09:10:47+00:00

The typo when using the MODULE_DEVICE_TABLE macro was not noticeable
because the macro was defined only if the module was built as a separate
module.

treewide: rename GPIO set callbacks back to their original names

2025-08-07T08:07:06+00:00

The conversion of all GPIO drivers to using the .set_rv() and
.set_multiple_rv() callbacks from struct gpio_chip (which - unlike their
predecessors - return an integer and allow the controller drivers to
indicate failures to users) is now complete and the legacy ones have
been removed. Rename the new callbacks back to their original names in
one sweeping change.

pinctrl: meson: support amlogic S6/S7/S7D SoC

2025-06-10T12:10:45+00:00

In some Amlogic SoCs, to save register space or due to some
abnormal arrangements, two sets of pins share one mux register.

A group starting from pin0 is the main pin group, which acquires
the register address through DTS and has management permissions,
but the register bit offset is undetermined.

Another GPIO group as a subordinate group. Some pins mux use share
register and bit offset from bit0 . But this group do not have
register management permissions.

This submission implements this situation.

pinctrl: meson: a4: remove special data processing

2025-06-10T12:10:37+00:00

According to the data specifications of Amlogic's existing SoCs,
the function register offset and the bit offset are the same
value among various chips. Therefore, general processing can
be carried out without the need for private data modification.
Drop special data processing.

Merge tag 'pinctrl-v6.16-1' of git://git.kernel.org/pub/scm/linux/kernel/git/linusw/linux-pinctrl

2025-05-30T16:46:28+00:00

Pull pin control updates from Linus Walleij:
 "An especially linear and sparse improvement and new drivers release.
  Nothing exciting. The biggest change in Bartosz changes to make
  gpiochip set/get calls return error codes (something we should have
  fixed ages ago but is now finally getting fixed.)

  Core changes:

   - Add the devres devm_pinctrl_register_mappings() call that can
     register some pin control machine mappings and have them go away
     with the associated device

  New drivers:

   - Support for the Mediatek MT6893 and MT8196 SoCs

   - Support for the Renesas RZ/V2N SoC

   - Support for the NXP Freescale i.MX943 SoC

  Improvements:

   - Per-SoC suspend/resume callbacks in the Samsung drivers

   - Set all pins as input (High-Z) at probe in the MCP23S08 driver

   - Switch most GPIO chips to use the setters/getters with a return
     value

   - EGPIO support in the Qualcomm QCM2290 driver

   - Fix up the number of available GPIO lines in Qualcomm QCS8300 and
     QCS615"
