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

2023-05-11T14:03:36+00:00

[ Upstream commit 7c19147d9cfc0f9328049d2e278279150d7de9ca ] There have been stable releases with the ralink,rt2880-pinmux compatible string included. Having it removed breaks the ABI. Reintroduce it.

pinctrl: ralink: Check for null return of devm_kcalloc

2022-07-11T12:40:17+00:00

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

2022-04-22T22:05:42+00:00

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.

pinctrl: ralink: rename variable names for functions on MT7620 and MT7621

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.
