2013-03-27gpio: mvebu: add dbg_show functionSimon Guinot
This patch adds a dedicated dbg_show function to the gpio-mvebu driver. In addition to the generic gpiolib informations, this function displays informations related with the specific Marvell registers (blink enable, data in polarity, interrupt masks and cause).

2013-03-06gpio/omap: convert gpio irq domain to linear mappingJon Hunter
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.
