* ARM: OMAP1: Fix a bunch of GPIO related section warnings after initdata got ↵Tony Lindgren2013-10-181-4/+4
| | | | | | | | | | | | | | | | | | | corrected Commit f8e7ba66 (ARM: OMAP1: fix incorrect placement of __initdata tag) fixed things but we started seeing section warnings. Looks like I missed those in my automatic build scripts: Section mismatch in reference from the variable omap7xx_gpio6 to the (unknown reference) .init.data:(unknown) Section mismatch in reference from the variable omap7xx_gpio6 to the (unknown reference) .init.data:(unknown) Section mismatch in reference from the variable omap7xx_gpio5 to the (unknown reference) .init.data:(unknown) ... Fix the issue by removing __initdata for the resources. Signed-off-by: Tony Lindgren <tony@atomide.com> Signed-off-by: Kevin Hilman <khilman@linaro.org>

* ARM: OMAP: Remove NEED_MACH_GPIO_HTony Lindgren2012-11-021-0/+2
| | | | | | | | | | | | | | | | | | Omap no longer needs this option, mach/gpio.h is empty. Also remove mach/irqs.h from gpio-omap.h and include it directly from the related omap1 gpio init files. Otherwise omap2+ build fails for MULTI_PLATFORM.

* ARM: OMAP: Move gpio.h to include/linux/platform_dataTony Lindgren2012-09-121-0/+1
| | | | | | | | | | | | | | | | | This way we can remove includes of plat/gpio.h which won't work with the single zImage support. Note that we also remove the cpu_class_is_omap2() check in gpio-omap.c as the drivers should not call it as we need to make it local to arch/arm/mach-omap2 for single zImage support. While at it, arrange the related includes in the standard way.

* gpio/omap: remove bank->method & METHOD_* macrosCharulatha V2012-02-061-2/+1
| | | | | | | | | | | | | | | | | | | The only bank->type (method) used in the OMAP GPIO driver is MPUIO type as they need to be handled separately. Identify the same using a flag and remove all METHOD_* macros. mpuio_init() function is defined under #ifdefs. It is required only in case of MPUIO bank type and only when PM operations are supported by it. This is applicable only in case of OMAP16xx SoC's MPUIO GPIO bank type. For all the other cases it is a dummy function. Hence clean up the same and remove all the OMAP SoC specific #ifdefs.

| * 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>

* | 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>.
