2010-05-05OMAP1: Amstrad Delta: add FIQ handler for serial keyboardport interrupt ↵Janusz Krzysztofik
processing This patch introduces a Fast Interrupt Request (FIQ) handler for Amstrad Delta (E3) videophone. The handler's purpose is to process interrupts generated by a GPIO line that a serial keyboard clock hangs off. It collects consecutive bits into words, pushing them into a buffer, then requests a higher level interrupt after one or more words are ready for further processing by a keyboard port driver. The handler also processes interrupts generated by two other GPIO lines, used by other on-board supported devices, by simply requesting a higher level interrupt, that in turn should invoke those device's specific irq handlers. IRQ12 line, not used by OMAP1510 hardware (described as reserved), has been choosen as a higher level interrupt source.
