* gpio: add API to be strict about GPIO IRQ usageLinus Walleij2013-10-161-2/+86
| | | | | | | | | | | | | | | | | | | | | | | | | | It is currently often possible in many GPIO drivers to request a GPIO line to be used as IRQ after calling gpio_to_irq() and, as the gpiolib is not aware of this, set the same line to output and start driving it, with undesired side effects. As it is a bogus usage scenario to request a line flagged as output to used as IRQ, we introduce APIs to let gpiolib track the use of a line as IRQ, and also set this flag from the userspace ABI. The API is symmetric so that lines can also be flagged from .irq_enable() and unflagged from IRQ by .irq_disable(). The debugfs file is altered so that we see if a line is reserved for IRQ.

* gpio: ep93xx: get rid of bogus __raw* accessorsLinus Walleij2013-10-161-9/+9
| | | | | | | | | | | | I have no idea why this driver is using __raw* accessors for reading and writing registers, I suspect it is just force of habit or copy/paste. Change all to readb()/writeb() except one chain where I used writeb_relaxed() up until the last writeb().

* gpio: stmpe: drop references to "virtual" IRQ, fix bugLinus Walleij2013-10-161-12/+13
| | | | | | | | | | | | | | | | | | | | | Rename the argument "virq" to just "irq", this IRQ isn't any more "virtual" than any other Linux IRQ number, we use "hwirq" for the actual hw-numbers, "virq" is just bogus. When doing this I see that the hwirq argument is used for mapping rather than the Linux IRQ in the map function. This doesn't look right. Use the Linux IRQ instead. I cannot test this patch so I don't know if the mapping change is correct, however since absolutely every other driver does it the other way around this doesn't look sound at all. Please help out with review.

* gpio: pca953x: Don't flip bits on PCA957x GPIO expanders when probing them.Graeme Smecher2013-09-231-11/+0
| | | | | | | | | | | | | | | | | | | | The pca957x driver supports a handful of I2C GPIO expanders from NXP, Maxim, and TI. For the PCA9574 and PCA9575 devices only, the driver resets the GPIO level and direction in the pca957x_probe function. This seems like the wrong thing to do, since it can cause hardware bit twiddles during warm reboots when the chip state and reset values don't match. This kind of initialization is best left upstream (in a bootloader) or downstream (in userspace). It's also an inconsistency across devices supported by this driver. This patch is NOT boot-tested: the SoC I'm using is stuck on 2.6.37, and the patch doesn't apply trivially.

* Remove GENERIC_HARDIRQ config optionMartin Schwidefsky2013-09-131-3/+3
| | | | | | | | After the last architecture switched to generic hard irqs the config options HAVE_GENERIC_HARDIRQS & GENERIC_HARDIRQS and the related code for !CONFIG_GENERIC_HARDIRQS can be removed. Signed-off-by: Martin Schwidefsky <schwidefsky@de.ibm.com>
