gpio-tz1090: add TZ1090 gpio driver
Add a GPIO driver for the main GPIOs found in the TZ1090 (Comet) SoC.
This doesn't include low-power GPIOs as they're controlled separately
via the Powerdown Controller (PDC) registers.
The driver is instantiated by device tree and supports interrupts for
all GPIOs.
Changes in v4:
- fix typos in DT bindings compatible properties
- reference Documentation/devicetree/bindings/gpio/gpio.txt in
gpio-ranges description in DT bindings
- fix gpio-ranges examples in DT bindings (it must now have 3 cells)
- gpio-tz1090: use of_property_read_u32 instead of of_get_property
Changes in v3:
- separated from irq-imgpdc and removed arch/metag changes to allow
these patches to go upstream separately via the pinctrl[/gpio] trees
(particularly the pinctrl drivers depend on the new pinconf DT
bindings).
- some s/unsigned/unsigned int/.
- some s/unsigned int/bool/ and use of BIT().
- gpio-tz1090*: refer to <dt-bindings/gpio/gpio.h> and
<dt-bindings/interrupt-controller/irq.h> flags in bindings.
- gpio-tz1090*: move initcall from postcore to subsys.
- gpio-tz1090: add REG_ prefix to some constants for consistency.
- gpio-tz1090: add comment to explain tz1090_gpio_irq_next_edge
cunningness.
Changes in v2:
- gpio-tz1090: remove references to Linux flags in dt bindings
- gpio-tz1090: make use of BIT() from linux/bitops.h
- gpio-tz1090: make register accessors inline to match pinctrl
- gpio-tz1090: update gpio-ranges to use 3 cells after recent ABI
