2013-01-26ARM: OMAP2+: omap_device: remove obsolete pm_lats and early_device codePaul Walmsley
Remove now-obsolete code from arch/arm/mach-omap2/omap_device.c. This mostly consists of removing the first attempt at device PM latency handling. This was never really used, has been replaced by the common dev_pm_qos code, and needs to go away as part of the DT conversion. Also, the early platform_device creation code has been removed, as it appears to be unused. Signed-off-by: Paul Walmsley <paul@pwsan.com> Cc: Kevin Hilman <khilman@deeprootsystems.com>

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.

2012-02-06gpio/omap: handle save/restore context in GPIO driverTarun Kanti DebBarma
Modify omap_gpio_prepare_for_idle() & omap_gpio_resume_after_idle() functions to handle save context & restore context respectively in the OMAP GPIO driver itself instead of calling these functions from pm specific files. For this, in gpio_prepare_for_idle(), call *_get_context_loss_count() and in gpio_resume_after_idle() call it again. If the count is different, do restore context.

2012-02-06gpio/omap: use flag to identify wakeup domainCharulatha V
In omap3, save/restore context is implemented for GPIO banks 2-6 as GPIO bank1 is in wakeup domain. Instead of identifying bank's power domain by bank id, use 'loses_context' flag which is filled by pwrdm_can_ever_lose_context() during dev_init. For getting the powerdomain pointer, omap_hwmod_get_pwrdm() is used. omap_device_get_pwrdm() could not be used as the pwrdm information needs to be filled in pdata, whereas omap_device_get_pwrdm() could be used only after omap_device_build() call.

2011-09-15OMAP: omap_device: when building return platform_device instead of omap_deviceKevin Hilman
All of the device init and device driver interaction with omap_device is done using platform_device pointers. To make this more explicit, have omap_device return a platform_device pointer instead of an omap_device pointer. All current users of the omap_device pointer were only using it to get at the platform_device pointer or struct device pointer, so fixing all of the users was trivial. This also makes it more difficult for device init code to directly access members of struct omap_device, and allows for easier changing of omap_device internals.

2011-07-12OMAP: PM: disable idle on suspend for GPIO and UARTKevin Hilman
Until these drivers are runtime PM converted, their device power states are managed by calling custom driver hooks late in the idle/suspend path. Therefore, do not let the suspend/resume core code automatically idle these devices since they will be managed manually by the OMAP PM core very late in the idle/suspend path.

2011-06-16gpio/omap: cleanup show revision, remove cpu_is checks, display only onceKevin Hilman
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>

Use omap_device_build() API to do platform_device_register of GPIO devices. For OMAP2+ chips, the device specific data defined in the centralized hwmod database will be used. gpio_init needs to be done before machine_init functions access gpio APIs. Hence gpio_init is made as a postcore_initcall.
