      OMAP1: Amstrad Delta: add FIQ handler for serial keyboardport interrupt processing · 60c3bf3f
      Janusz Krzysztofik 提交于
      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.
