pinctrl: ralink: move to mediatek as mtmips

2023-03-19T20:47:25Z

This platform from Ralink was acquired by MediaTek in 2011. Then, MediaTek introduced new SoCs which utilise this platform. Move the driver to mediatek pinctrl directory. Rename the ralink core driver to mtmips. Signed-off-by: Arınç ÜNAL Link: https://lore.kernel.org/r/20230317213011.13656-5-arinc.unal@arinc9.com Signed-off-by: Linus Walleij

pinctrl: ralink: mt7620: split out to mt76x8

2023-03-19T20:47:25Z

Split the driver out to pinctrl-mt76x8.c. Remove including the unnecessary headers since is_mt76x8() is not being used anymore. Introduce a new compatible string to be able to document the pin muxing information properly.

pinctrl: ralink: rt305x: add new compatible string for every SoC

2023-03-19T20:47:25Z

Add new compatible strings to make every SoC, or SoCs that use the same pinmux data have a unique compatible string. This ensures that the pin muxing information of every SoC, or a set of SoCs that use the same pinmux data can be properly documented.

pinctrl: ralink: reintroduce ralink,rt2880-pinmux compatible string

2023-03-19T20:47:25Z

There have been stable releases with the ralink,rt2880-pinmux compatible string included. Having it removed breaks the ABI. Reintroduce it.

pinctrl: ralink: rename variables which point out the pin group

2023-01-16T13:56:46Z

These variables define a list of functions which can be muxed to the pin group which the name of the pin group was originally intended to be pointed out on the name of the said variables. Therefore, rename "func" to "grp" across all subdrivers where this applies.

pinctrl: ralink: Check for null return of devm_kcalloc

2022-07-11T12:40:17Z

Because of the possible failure of the allocation, data->domains might be NULL pointer and will cause the dereference of the NULL pointer later. Therefore, it might be better to check it and directly return -ENOMEM without releasing data manually if fails, because the comment of the devm_kmalloc() says "Memory allocated with this function is automatically freed on driver detach.".

pinctrl: ralink: add new compatible strings for each pinctrl subdriver

2022-04-22T22:05:42Z

As seen on any other pinctrl subdriver that calls code from a main driver, each subdriver needs to have a different compatible string. We don't want the same compatible string to match a different subdriver's pinmux data as it's not for our SoC. Therefore, add new compatible strings for each pinctrl subdriver. Change driver name on all subdrivers accordingly.

2022-04-22T22:05:42Z

MT7620, MT7621, RT2880, RT305X and RT3883 pinctrl are subdrivers of the Ralink pinctrl driver. Change the bool for these subdrivers accordingly.

Variables for functions include "grp" on the Ralink MT7620 and MT7621 subdrivers. Rename them to "func" instead as they define the functions for the pin groups.

Rename "pinctrl-rt288x.c" to "pinctrl-rt2880.c" as this is the Ralink RT2880 pinctrl subdriver. Rename PINCTRL_RT288X symbol to PINCTRL_RT2880. Rename functions that include "rt288x" to "rt2880".
