pinctrl: mediatek: set array size for reg_cals

2026-01-21T19:29:25Z

Set the size of the reg_cals arrays to PINCTRL_PIN_REG_MAX to in all affected mediatek pinctrl drivers. This is needed to avoid potential out-of-bounds accesses when they is used in mtk_hw_pin_field_get(). All array members need to be initialized since the code loops from 0 to PINCTRL_PIN_REG_MAX - 1. mt7622_reg_cals was already defined this way, but the others were not. Signed-off-by: David Lechner

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

pinctrl: mt7629: add jtag function and pin group

2021-03-20T20:24:27Z

The EPHY LEDs of mt7629 can be used as JTAG. This patch adds the jtag pin group to the pinctrl driver. 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

pinctrl: MediaTek: add pinctrl driver for MT7629 SoC

2018-11-29T04:04:52Z

This patch adds pinctrl support for MT7629 SoC. The IO core found on the SoC has the registers for pinctrl, pinconf and gpio mixed up in the same register range. Hence the driver also implements the gpio functionality through UCLASS_GPIO. This also creates a common file as there might be other chips that use the same binding and driver, then being a little more abstract could help in the long run.
