* OMAP1: Amstrad Delta: add a handler for processing interruptsgenerated by ↵Janusz Krzysztofik2010-05-051-0/+7
| | | | | | | | | | | | | | | | | the FIQ routine This patch introduces an IRQ handler used for processing interrupts generated by the FIQ handler when it decides there are data ready for processing. The handler further invokes device specific interrupt routines based on interrupt source counters passed from the FIQ handler. The handler setup function is intended to be called from the board provided init_machine() callback.

* OMAP1: Amstrad Delta: add FIQ handler for serial keyboardport interrupt ↵Janusz Krzysztofik2010-05-051-0/+72
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.
