pinctrl: mediatek: mt8189: align register base names to dt-bindings ones

2025-12-01T10:45:49+00:00

[ Upstream commit 518919276c4119e34e24334003af70ab12477f00 ] The mt8189-pinctrl driver requires to probe that a device tree uses in the device node the same names than mt8189_pinctrl_register_base_names array. But they are not matching the required ones in the "mediatek,mt8189-pinctrl" dt-bindings, leading to possible dtbs check issues. The mt8189_pinctrl_register_base_names entry order is also different. So, align all mt8189_pinctrl_register_base_names entry names and order on dt-bindings.

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.

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. Signed-off-by: Bartosz Golaszewski

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().
