2011-06-16gpio/tegra: Move Tegra gpio driver to drivers/gpioGrant Likely2-0/+432
As part of the gpio driver consolidation, this patch moves the Tegra driver into drivers/gpio Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: Olof Johansson <olof@lixom.net> Acked-by: Colin Cross <ccross@android.com>
2011-06-13gpio/74x164: fix clash with gpiolib namespaceLinus Walleij1-3/+3
The 74x164 GPIO driver has a static inline helper called gpio_to_chip which clashes with the gpiolib namespace if we try to expose the function with the same name from gpiolib, and it's still confusing even if we don't do that. So rename it to gpio_to_74x164_chip().

2011-06-10treewide: Convert uses of struct resource to resource_size(ptr)Joe Perches1-4/+4
Several fixes as well where the +1 was missing. Done via coccinelle scripts like: @@ struct resource *ptr; @@ - ptr->end - ptr->start + 1 + resource_size(ptr) and some grep and typing.

2011-06-08gpio/pca953x: Fix warning of enabled interrupts in handlerDavid Jander1-3/+3

2011-06-07GPIO: OMAP: fix setting IRQWAKEN bits for OMAP4Colin Cross1-10/+2
Setting the IRQWAKEN bit was overwriting previous IRQWAKEN bits, causing only the last bit set to take effect, resulting in lost wakeups when the GPIO controller is in idle.

The patch makes necessary changes on gpio-mxc as below to turn it into an upstanding gpio driver. * Add a list to save all mx2 ports references, so that mx2_gpio_irq_handler can walk through all interrupt status registers * Use readl/writel to replace mach-specific accessors __raw_readl/__raw_writel * Change mxc_gpio_init into mxc_gpio_probe function * Move "struct mxc_gpio_port" into gpio-mxc.c, as it needs not to be public at all, and also make some other cleanup on plat-mxc/include/mach/gpio.h at the same time And the patch then migrates mach-imx and mach-mx5 to the updated driver by adding corresponding platform devices.
