Subject[PATCH v3 0/2] GPIO: add single-register GPIO via CREG driver
Date
Add single-register MMIO GPIO driver for complex cases where
only several fields in register belong to GPIO lines and each GPIO
line owns a field with different length and on/off value.

Such CREG GPIOs are used in Synopsys AXS10x and HSDK boards.

Changes v2->v3:
* Move parameters into a lookup table instead of device tree.
* Use the ngpios attribute for instead of snps,ngpios.
