pinctrl: airoha: fix wrong MDIO function bitmaks

2025-09-08T21:01:19+00:00

With further testing with an attached Aeonsemi it was discovered that
the pinctrl MDIO function applied the wrong bitmask. The error was
probably caused by the confusing documentation related to these bits.

Inspecting what the bootloader actually configure, the SGMII_MDIO_MODE
is never actually set but instead it's set force enable to the 2 GPIO
(gpio 1-2) for MDC and MDIO pin.

The usage of GPIO might be confusing but this is just to instruct the
SoC to not mess with those 2 PIN and as Benjamin reported it's also an
Errata of 7581. The FORCE_GPIO_EN doesn't set them as GPIO function
(that is configured by a different register) but it's really to actually
""enable"" those lines.

Normally the SoC should autodetect this by HW but it seems AN7581 have
problem with this and require this workaround to force enable the 2 pin.

Applying this configuration permits correct functionality of any
externally attached PHY.

pinctrl: airoha: fix wrong PHY LED mux value for LED1 GPIO46

2025-09-08T13:01:39+00:00

In all the MUX value for LED1 GPIO46 there is a Copy-Paste error where
the MUX value is set to LED0_MODE_MASK instead of LED1_MODE_MASK.

This wasn't notice as there were no board that made use of the
secondary PHY LED but looking at the internal Documentation the actual
value should be LED1_MODE_MASK similar to the other GPIO entry.

Fix the wrong value to apply the correct MUX configuration.

pinctrl: airoha: Fix return value in pinconf callbacks

2025-08-22T13:08:58+00:00

Pinctrl stack requires ENOTSUPP error code if the parameter is not
supported by the pinctrl driver. Fix the returned error code in pinconf
callbacks if the operation is not supported.

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: Use dev_fwnode()

2025-06-18T11:32:11+00:00

irq_domain_create_simple() takes fwnode as the first argument. It can be
extracted from the struct device using dev_fwnode() helper instead of
using of_node with of_fwnode_handle().

So use the dev_fwnode() helper.

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"
