2011-05-11ARM: tegra: update GPIO chained IRQ handler to use entry/exit functionsWill Deacon
This patch updates the Tegra gpio chained IRQ handler to use the chained IRQ enter/exit functions in order to function correctly on primary controllers with different methods of flow control. This is required for the GIC to move to fasteoi interrupt handling. Acked-by: Colin Cross <ccross@android.com> Signed-off-by: Will Deacon <will.deacon@arm.com>
2011-03-30ARM: tegra: gpio: Fix unused variable warningsColin Cross
Change b0f18edaf6ee4e6fac89cae63a90bd38ad2a3418 (arm: tegra: Remove unused bogus irq enable/disable magic) introduces warnings: arch/arm/mach-tegra/gpio.c: In function 'tegra_gpio_resume': arch/arm/mach-tegra/gpio.c:260: warning: unused variable 'i' arch/arm/mach-tegra/gpio.c: In function 'tegra_gpio_suspend': arch/arm/mach-tegra/gpio.c:283: warning: unused variable 'i' Fix them, and fix a coding style issue on the same lines.

2011-03-29arm: Fold irq_set_chip/irq_set_handlerThomas Gleixner
Use irq_set_chip_and_handler() instead. Converted with coccinelle. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-29arm: Cleanup the irq namespaceThomas Gleixner
Convert to the new function names. Automated with coccinelle. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
2011-03-29arm: Use genirq lockdep helper to set lock classThomas Gleixner
Remove the open coded access to irq_desc which will fail on sparse irq and use the proper wrappers. Signed-off-by: Thomas Gleixner <tglx@linutronix.de>

2011-02-22ARM: tegra: add tegra_gpio_table and tegra_gpio_configOlof Johansson
To give one place to setup the pins that are used as GPIOs instead of as their pinmuxed functions. Specifying enabled as false explicitly disables the gpio mode of that pin (if left on by firmware). This should remove the need for calling these from specific drivers and thus reduce tegra-specific code from them.

Commit 37337a8d5e68d6e19075dbdb3acf4f1011dae972, "ARM: tegra: irq_data conversion." missed changing one reference to 'irq' in the function tegra_gpio_irq_set_type(). This patch fixes the build error.
