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 breakage Signed-off-by: James Hogan <james.hogan@imgtec.com> Cc: Grant Likely <grant.likely@linaro.org> Cc: Rob Herring <rob.herring@calxeda.com> Cc: Rob Landley <rob@landley.net> Cc: Linus Walleij <linus.walleij@linaro.org> Cc: linux-doc@vger.kernel.org Cc: devicetree-discuss@lists.ozlabs.org Signed-off-by: Linus Walleij <linus.walleij@linaro.org> |
