gpio/omap: cleanup show revision, remove cpu_is checks, display only once
Remove cpu_is_* checks from gpio_show_revision() by passing in the revision address offset from platform data. SoCs with no revision register (15xx, 7xx, and all MPUIOs) use -1 (actually, USHRT_MAX) to signify no register. While here, all GPIO banks are assumed to be the same revision, so fix show_revision() to only show the revision for the first bank it finds. This removes duplicate GPIO revision prints during boot. Thanks to Charulatha V <charu@ti.com> for finding/fixing a few -1s that were missed in the original patch. Signed-off-by: Kevin Hilman <khilman@ti.com>
