From 9caf1f2202da2affedf0c9e3c1ccda8ea6d353e1 Mon Sep 17 00:00:00 2001 From: James Hogan Date: Tue, 25 Jun 2013 15:27:43 +0100 Subject: 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 and 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 Cc: Grant Likely Cc: Rob Herring Cc: Rob Landley Cc: Linus Walleij Cc: linux-doc@vger.kernel.org Cc: devicetree-discuss@lists.ozlabs.org Signed-off-by: Linus Walleij --- drivers/gpio/Kconfig | 7 +++++++ 1 file changed, 7 insertions(+) (limited to 'drivers/gpio/Kconfig') diff --git a/drivers/gpio/Kconfig b/drivers/gpio/Kconfig index b2450ba..e976164 100644 --- a/drivers/gpio/Kconfig +++ b/drivers/gpio/Kconfig @@ -242,6 +242,13 @@ config GPIO_TS5500 blocks of the TS-5500: DIO1, DIO2 and the LCD port, and the TS-5600 LCD port. +config GPIO_TZ1090 + bool "Toumaz Xenif TZ1090 GPIO support" + depends on SOC_TZ1090 + default y + help + Say yes here to support Toumaz Xenif TZ1090 GPIOs. + config GPIO_XILINX bool "Xilinx GPIO support" depends on PPC_OF || MICROBLAZE || ARCH_ZYNQ -- cgit v1.1
