pinctrl: meson: add a new callback for SoCs fixup
In meson_pinctrl_parse_dt, it contains two parts: reg parsing and
SoC relative fixup for AO. 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.
