* GPIO: add single-register GPIO via CREG driverEugeniy Paltsev2018-10-101-0/+191
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. Signed-off-by: Eugeniy Paltsev <Eugeniy.Paltsev@synopsys.com> Signed-off-by: Linus Walleij <linus.walleij@linaro.org>
