After discussion with the devicetree maintainers we agreed to not extend lists with the generic compatible "apple,pinctrl" anymore [1]. Use "apple,t8103-pinctrl" as fallback compatible as it is the SoC driver and bindings were originally written for. The t602x (M2 Pro/Max/Ultra) devicetrees submitted in [2] use this compatible as fallback instead of "apple,t8103-pinctrl".

Boards based on the Allwinner D1/T113-s3, such as the NetCube Systems Nagami, can expose a third I2C controller on PG10/PG11. However, the sun20i_d1 pinctrl function table lacked an entry for this mux. Add the "i2c3" function with mux value 3 on PG10/PG11, allowing device trees to enable the I2C3 controller.

In the original code, I wrote a custom pin muxing parser but the
upstream device trees wouldn't accept something like that so it would
have complicated mergine the device tree files.
Use the standard device tree format with function and groups:
pinmux1: pinmux1 {
function = "f_gpio1";
groups = "grp_1", "grp_3";
};

This is the first wave of MediaTek changes for this merge window. We also expect to be sending another decent-sized pull request later for the backlog of patches that are currently waiting on dependencies or need little more time for review. * Fixes for cargo-culted issues in mach-mediatek init.c files. * Some consistency cleanups of recently added Genio boards (510/700/1200). * Some pinctrl improvements to support newer MediaTek SOCs (mt8189 compatible). * New devicetree and config for Genio 520/720 EVK boards (can boot to eMMC or SD). * New CPU-specific functions to read vendor-specific CPU info at runtime.
The U_BOOT_DRIVER macro creates a list of drivers used at link time, and all entries here must be unique. This in turn means that all entries in the code should also be unique in order to not lead to build failures later with unexpected build combinations. Typically, the problem we have here is when a driver is obviously based on another driver and didn't update this particular field and so while the name field reflects something unique the linker entry itself is not. In a few places this provides a more suitable string name as well, however.
