This patch includes the following changes: - Using irqsave/irqrestore spinlock variants to avoid any potential deadlock in case of GPIO as IRQ - Introducing a new device tree option 'pin-cfg' which can be used to setup mode of one or several GPIO pins. It can be used to choose pin's function, filtes, polarity and direction. - Extending PIN_SEL_MASK to cover for otx2 platform - In case of level irq, the current handle is not unmasking the GPIO interrupt, so using handle_level_irq, which will allow next interrupt to be handled. All the changes have been internally verified on Marvell otx2 platforms.
