| * gpio/omap: cleanup show revision, remove cpu_is checks, display only onceKevin Hilman2011-06-161-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>
| * gpio/omap: conslidate enable/disable of GPIO IRQs, remove ifdefsKevin Hilman2011-06-161-0/+4
| | | | | | | | | | | | | | | | | | | | Cleanup GPIO IRQ enable/disable handling by removing SoC-specific Also split enable/disable IRQ into separate functions for better readability and also facilitate potentially moving to generic irq_chip in the future.

| * gpio/omap: consolidate IRQ status handling, remove #ifdefsKevin Hilman2011-06-161-0/+2
| | | | | | | | | | | | | | | | | | Cleanup IRQ status handling by passing IRQ status register offsets via platform data. Cleans up clearing of GPIO IRQ status and GPIO ISR handler. Signed-off-by: Kevin Hilman <khilman@ti.com>
| * gpio/omap: consolidate direction, input, output, remove #ifdefsKevin Hilman2011-06-161-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add register offset fields to GPIO platform_data for registers. This patch adds registers that control direction, input and output data. Using these register offsets in the common driver allows removal of #ifdefs and greatly improves readability. Also create dedicated data out functions: one for banks with dedicated set/clear registers, and another for banks with a single mask register. Signed-off-by: Kevin Hilman <khilman@ti.com>
* | omap: drop __initdata tags from static struct platform_device declarationsJanusz Krzysztofik2011-07-041-2/+2
|/ | | | | | | | | | | | | | | | | | | | | | Pointers to statically declared platform device structures which are registered with platform_device_register() are then used during run time to access these structure members, for example from platform_uevent() and much more. Therefore, these structures should never be placed inside sections which are dropped after boot. Fix platform devices incorrectly tagged with __initdata which happen to exist inside OMAP sub-trees. This bug has exhibited itself on my ARM/OMAP1 based Amstrad Delta videophone after commit 6d3163ce86dd386b4f7bda80241d7fea2bc0bb1d, "mm: check if any page in a pageblock is reserved before marking it MIGRATE_RESERVE", resulting in reading from several /sys/device/platform/*/uevent files always ending up with segmentation faults.

* omap1: Fix gpio mpuio bank to work for multi-omap for 7xx/15xx/16xxTony Lindgren2010-12-071-0/+1
| | | | | | | | | | | | | | | We need to divide the 15xx/16xx offset by 2 for 7xx. Use bank->stride for that. This allows us to get rid of the duplicate defines for the MPUIO registers. Note that this will cause omap-keypad.c driver to not work on 7xx. However, the right fix there is to move over to matrix_keypad instead as suggested by Cory Maccarrone <darkstar6262@gmail.com> and Janusz Krzysztofik <jkrzyszt@tis.icnet.pl>.
