pinctrl: mediatek: Bind gpio while binding pinctrl

2024-10-07T21:09:55Z

Mediatek pinctrl drivers call mtk_gpiochip_register() to bind the child gpio controller as part of mtk_pinctrl_common_probe(). This breaks gpiohog support because the gpio controller is bound too late for DM_FLAG_PROBE_AFTER_BIND (set while binding hogs) to work. Move the mtk_gpiochip_register() to mtk_pinctrl_common_bind() and call this as the .bind method of each of the mediatek pinctrl drivers. Signed-off-by: Chris Webb

pinctrl: mediatek: convert most definitions to const

2023-08-03T13:40:50Z

There exists a situation of the mediatek pinctrl driver that may return wrong pin function value for the pinmux driver: - All pin function arrays are defined without const - Some pin function arrays contain all-zero value, e.g.: static int mt7622_spi_funcs[] = { 0, 0, 0, 0, 0, 0, }; - These arrays will be put into .bss section during compilation - .bss section has no "a" attribute and does not exist in the final binary file after objcopy. - FDT binary blob is appended to the u-boot binary, which occupies the .bss section. - During board_f stage, .bss has not been initialized, and contains the data of FDT, which is not full-zero data. - pinctrl driver is initialized in board_f stage, and it will get wrong data if another driver is going to set default pinctrl. Since pinmux information and soc data are only meant to be read-only, thus should be declared as const. This will force all pinctrl data being put into .rodata section. Since .rodata has "a" attribute, even the all-zero data will be allocated and filled with correct value in to u-boot binary. Signed-off-by: Weijie Gao

dm: treewide: Rename auto_alloc_size members to be shorter

2020-12-13T15:00:25Z

This construct is quite long-winded. In earlier days it made some sense since auto-allocation was a strange concept. But with driver model now used pretty universally, we can shorten this to 'auto'. This reduces verbosity and makes it easier to read. Coincidentally it also ensures that every declaration is on one line, thus making dtoc's job easier. Signed-off-by: Simon Glass

pinctrl: mediatek: add support for different pinctrl

2020-01-16T14:39:45Z

Due to the pinctrl hardware of MT7622 is difference from others SoC which using the common part of mediatek pinctrl. So we need to modify the common part of mediatek pinctrl. Signed-off-by: Sam Shih Reviewed-by: Ryder Lee
