Begin cleanup and consolidation of OMAP GPIO driver by starting the
removal of SoC specifics (ifdefs, cpu_is-* checks, etc.) The primary
method for this is by passing register offsets for common
functionality via platform_data, so the driver can be generic.
This series currently handles the GPIO direction, data in/out, IRQ
status and IRQ enable/disable functions, but does not yet handle the
IRQ triggering and suspend/resume handling. That will be coming next.
I'll not be working on this for the next week, so anyone who wants to
build on this is more than welcome.
This work in progress is available in my wip/gpio-cleanup branch.
This series applies on top of v2.6.39-rc4 plus the generic irq_chip
series from Thomas Gleixner since in addition to the cleanups, I
started moving the GPIO IRQ handling over to use generic irq_chip
(last patch in series.)
Yes, there is much about OMAP GPIOs that is common to GPIO handling on
other SoCs. However, before we can consolidate with other SoCs, the
first step is to consolidate to a single, clean driver for all OMAPs.
After that, we can start looking at consolidation with other SoCs.
