ARM: pxa: pxa_cplds: add lubbock and mainstone IO
Historically, this support was in arch/arm/mach-pxa/lubbock.c and arch/arm/mach-pxa/mainstone.c. When gpio-pxa was moved to drivers/pxa, it became a driver, and its initialization and probing happened at postcore initcall. The lubbock code used to install the chained lubbock interrupt handler at init_irq() time. The consequence of the gpio-pxa change is that the installed chained irq handler lubbock_irq_handler() was overwritten in pxa_gpio_probe(_dt)(), removing : - the handler - the falling edge detection setting of GPIO0, which revealed the interrupt request from the lubbock IO board. As a fix, move the gpio0 chained handler setup to a place where we have the guarantee that pxa_gpio_probe() was called before, so that lubbock handler becomes the true IRQ chained handler of GPIO0, demuxing the lubbock IO board interrupts. This patch moves all that handling to a mfd driver. It's only purpose for the time being is the interrupt handling, but in the future it should encompass all the motherboard CPLDs handling : - leds - switches - hexleds The same logic applies to mainstone board.
