2013-10-16gpio: lpc32xx: Include linux/of.h headerSachin Kamat1-0/+1
'of_match_ptr' is defined in linux/of.h. Include it explicitly to avoid build breakage in the future. Signed-off-by: Sachin Kamat <[email protected]> Signed-off-by: Linus Walleij <[email protected]>

Pull removal of GENERIC_GPIO from Grant Likely: "GENERIC_GPIO now synonymous with GPIOLIB. There are no longer any valid cases for enableing GENERIC_GPIO without GPIOLIB, even though it is possible to do so which has been causing confusion and breakage. This branch does the work to completely eliminate GENERIC_GPIO." * tag 'gpio-for-linus' of git://git.secretlab.ca/git/linux: gpio: update gpio Chinese documentation Remove GENERIC_GPIO config option Convert selectors of GENERIC_GPIO to GPIOLIB blackfin: force use of gpiolib m68k: coldfire: use gpiolib mips: pnx833x: remove requirement for GENERIC_GPIO openrisc: default GENERIC_GPIO to false avr32: default GENERIC_GPIO to false xtensa: remove explicit selection of GENERIC_GPIO sh: replace CONFIG_GENERIC_GPIO by CONFIG_GPIOLIB powerpc: remove redundant GENERIC_GPIO selection unicore32: default GENERIC_GPIO to false unicore32: remove unneeded select GENERIC_GPIO arm: plat-orion: use GPIO driver on CONFIG_GPIOLIB arm: remove redundant GENERIC_GPIO selection mips: alchemy: require gpiolib mips: txx9: change GENERIC_GPIO to GPIOLIB mips: loongson: use GPIO driver on CONFIG_GPIOLIB mips: remove redundant GENERIC_GPIO select
2013-04-16Remove GENERIC_GPIO config optionAlexandre Courbot1-1/+1
GENERIC_GPIO has been made equivalent to GPIOLIB in architecture code and all driver code has been switch to depend on GPIOLIB. It is thus safe to have GENERIC_GPIO removed.

2012-09-30gpio-lpc32xx: Add GPI_28Roland Stigge1-1/+2
This patch adds the missing gpi28 to the list of GPIOs in the GPI P3 "chip". NOTE: This patch depends on incrementing LPC32XX_GPI_P3_MAX. When applied without the respective mach-lpc32xx patch (merged via arm-soc.git), gcc will give a warning about "excess elements in array initializer" but this doesn't harm.

2012-09-24gpio-lpc32xx: Fix value handling of gpio_direction_output()Roland Stigge1-0/+5
For GPIOs of gpio-lpc32xx, gpio_direction_output() ignores the value argument (initial value of output). This patch fixes this by setting the level accordingly.

2012-07-12gpio: LPC32xx: Driver cleanupRoland Stigge1-8/+1
Since LPC32xx is now switched over to devicetree based GPIO, the unused lpc32xx_gpio_init() can be removed. Further, the driver title changed since it referred to the wrong file. Signed-off-by: Roland Stigge <[email protected]> Signed-off-by: Linus Walleij <[email protected]>
2012-05-18gpio/lpc32xx: Add device tree supportRoland Stigge1-1/+51
This patch adds device tree support for gpio-lpc32xx.c. To register the various GPIO banks as (struct) gpio_chips via the same DT gpio-controller, we utilize the adjusted of_xlate API to manipulate the actually used struct gpio_chip.

2012-03-12GPIO: LPC32xx: Add output reading to GPO P3Roland Stigge1-0/+17
The chip offers the function to detect the current state of output of the GPO P3 pins. Useful for reading GPIO output state in Linux' GPIO API, e.g. via sysfs. Please note that this only reads back the currently programmed output state, not the actual electrical level in terms of a GPI function. Finally, GPO3 is still just an output.
