Several fixups in the same code make it hard to maintain, so move all fixups to each SoC's callback and make meson_pinctrl_parse_dt just do the reg parsing, separate these two parts.Overview of all current Meson SoCs fixup is as below: +------+--------------------------------------+--------------------------+ | | | | | SoC | EE domain | AO domain | +------+--------------------------------------+--------------------------+ |m8 | parse regs: | parse regs: | |m8b | gpio,mux,pull,pull-enable(skip ds) | gpio,mux,pull(skip ds)| |gxl | fixup: | fixup: | |gxbb | no | pull-enable = pull; | |axg | | | +------+--------------------------------------+--------------------------+ |g12a | parse regs: | parse regs: | |sm1 | gpio,mux,pull,pull-enable,ds | gpio,mux,ds | | | fixup: | fixup: | | | no | pull = gpio; | | | | pull-enable = gpio; | +------+--------------------------------------+--------------------------+ |a1 or | parse regs: | |later | gpio/mux (without ao domain) | |SoCs | fixup: | | | pull = gpio; pull-enable = gpio; ds = gpio; | +------+-----------------------------------------------------------------+ Since m8-axg share the same ao fixup, make a common function meson8_aobus_parse_dt_extra to do the job.
