For OMAP devices, if a gpio is being used as an interrupt source but has not been requested by calling gpio_request(), a call to request_irq() may cause the kernel hang because the gpio bank may be disabled and hence the register access will fail.

2013-03-06gpio/omap: convert gpio irq domain to linear mappingJon Hunter1-41/+31
Currently the OMAP GPIO driver uses a legacy mapping for the GPIO IRQ domain. This is not necessary because we do not need to assign a specific interrupt number to the GPIO IRQ domain. Therefore, convert the OMAP GPIO driver to use a linear mapping instead. Please note that this also allows to simplify the logic in the OMAP gpio_irq_handler() routine, by using irq_find_mapping() to obtain the virtual irq number from the GPIO bank and bank index.

2013-03-05ARM: S3C24XX: handle s3c2412 eints using new infrastructureHeiko Stuebner1-1/+4
The s3c2412 handles the eints 0 to 3 different than all the other SoCs of the 24xx range. These eints must be acked and masked in the regular bits as well as the bits 0 to 3 of the eint registers, which are unused on the other SoCs. This of course can be realized using the new infrastructure with the eint bits in the main register being the parent interrupts of the same bits in the eint register. The s3c2412 therefore gets its own IRQ_EINT0 to 4 constants that reside in the newly created gap before IRQ_EINT4. gpio-samsung, as the only user of these is modified to return the correct values when handling gpio_to_irq requests on s3c2412 based machines. Due to lack of hardware this is compile tested only, but should hopefully work as intended. Signed-off-by: Heiko Stuebner <[email protected]> Signed-off-by: Kukjin Kim <[email protected]>
