The patch adds initialization of FIQ related handlers to the Amstrad Delta videophone board code. FIQ will be used instead of a traditional IRQ for processing all GPIO generated interrupts, including a keyboard serial clock line.
Created and tested against linux-omap master, commit 104a77440f05430f29f9d3f4ecb88c1536819585 dated 2010-04-27.
Compiles and works on top of PATCH v4 2/5(7), "OMAP1: Amstrad Delta: add a handler for processing interrupts generated by the FIQ routine". Also requires PATCH v4 2.1/5(7), "OMAP1: Amstrad Delta: update board initialization code for complete modem IRQ GPIO line setup" for correct modem handling.
Compile tested with a bunch of OMAP15XX/OMAP16XX boards selected simultaneously.
