2023-04-10soc/mediatek/mt8186: Move GPIO driving-related functions to commonJason Chen
Move GPIO driving-related functions to common for code reuse.

2023-04-10soc/mediatek/mt8186: Reduce GPIO code size in bootblockJason Chen
Create a new GPIO driving info table that contains only the pins used in the bootblock. The GPIO driving info table is downsized from 1480 bytes to 24 bytes.

2022-07-06soc/mediatek: Move some gpio functions to common/gpio_op.cRex-BC Chen
gpio_set_pull(), gpio_set_pull_pu_pd() and gpio_set_spec_pull_pupd() can be reused for mt8192, mt8195 and mt8186, so move it to new file "gpio_op.c" in common folder.

2022-03-09soc/mediatek/mt8186: Add GPIO driving functionsGuodong Liu
Add GPIO driving functions to adjust pin driving. The value of drive strength is different for each SoC, so we define GPIO_DRV0 to GPIO_DRV7 which are corresponding to 2/4/6/8/10/12/14/16mA in MT8186. This implementation is according to chapter 5.1 in MT8186 Functional Specification.
