drivercore: Add helper macro for platform_driver boilerplate

2011-10-24T22:35:47Z

For simple modules that contain a single platform_driver without any additional setup code then ends up being a block of duplicated boilerplate. This patch adds a new macro, module_platform_driver(), which replaces the module_init()/module_exit() registrations with template functions.

new helper to create platform devices with dma mask

2011-08-26T18:31:09Z

compared to the most powerful and already existing helper (namely platform_device_register_resndata) this allows to specify a dma_mask. To make eventual extensions later more easy, a struct holding the used information is created instead of passing the information by function parameters.

driver core: Add ability for arch code to setup pdev_archdata

2011-07-08T05:21:35Z

On some architectures we need to setup pdev_archdata before we add the device. Waiting til a bus_notifier is too late since we might need the pdev_archdata in the bus notifier. One example is setting up of dma_mask pointers such that it can be used in a bus_notifier. We add weak noop version of arch_setup_pdev_archdata() and allow the arch code to override with access the full definitions of struct device, struct platform_device, and struct pdev_archdata.

PM: Revert "driver core: platform_bus: allow runtime override of dev_pm_ops"

2011-05-16T18:17:47Z

The platform_bus_set_pm_ops() operation is deprecated in favor of the new device power domain infrastructre implemented in commit 7538e3db6e015e890825fbd9f8659952896ddd5b (PM: add support for device power domains) Signed-off-by: Kevin Hilman Signed-off-by: Rafael J. Wysocki

PM: Export platform bus type's default PM callbacks

Export the default PM callbacks defined for the platform bus type so that they can be used by power domains for suspending and resuming platform devices in the future. Signed-off-by: Rafael J. Wysocki

mfd: Fetch cell pointer from platform_device->mfd_cell

2011-04-12T09:13:00Z

In order for MFD drivers to fetch their cell pointer but also their platform data one, an mfd cell pointer is added to the platform_device structure. That allows all MFD sub devices drivers to be MFD agnostic, unless they really need to access their MFD cell data. Most of them don't, especially the ones for IPs used by both MFD and non MFD SoCs.

driver core: platform_bus: allow runtime override of dev_pm_ops

2010-10-22T17:16:42Z

Currently, the platform_bus allows customization of several of the busses dev_pm_ops methods by using weak symbols so that platform code can override them. The weak-symbol approach is not scalable when wanting to support multiple platforms in a single kernel binary. Instead, provide __init methods for platform code to customize the dev_pm_ops methods at runtime. NOTE: after these dynamic methods are merged, the weak symbols should be removed from drivers/base/platform.c. AFAIK, this will only affect SH and sh-mobile which should be converted to use this runtime approach instead of the weak symbols. After SH & sh-mobile are converted, the weak symobols could be removed. Tested on OMAP3. Cc: Magnus Damm Acked-by: Grant Likely Signed-off-by: Kevin Hilman Signed-off-by: Greg Kroah-Hartman

Driver core: reduce duplicated code for platform_device creation
