This patch was to add loongson 2k0500, 2k2000 and 3a5000 gpio chip
driver support.
Change in v4:
1. Reword the title and commit log information.
2. Remove the offset parse in DT and add it in of_device_id and
acpi_device_id's data field.
3. Add more gpio chip dt-bindings support in yaml file.
Change in v3:
1. Reword the dt-bindings patch commit log information.
2. Add "loongson,ls2k1000-gpio" compatible.
Change in v2:
1. Reword the patch commit log information.
2. Add some GPIO register offset description in yaml.

Are there going to be more controllers that are compatible with
"ls7a-gpio"? If not, you can simplify both of these to have 2 const:
entries, like:
- items:
- const: loongson,ls2k1000-gpio
- const: loongson,ls2k-gpio
- items:
- const: loongson,ls7a1000-gpio
- const: loongson,ls7a-gpio
Either way,

Thanks for sticking at this one :)
