drivercore: Generalize module_platform_driver

2012-04-16T10:49:10+00:00

This patch generalizes the module_platform_driver macro and introduces a new
module_driver macro. The module_driver macro takes a driver name, a register
and a unregister function for this driver type. Using these it construct the
module init and exit sections which register and unregister the driver. Since
such init/exit sections are commonly found in drivers this macro can be used
to eliminate a lot of boilerplate code.

The macro is not intended to be used by driver modules directly, instead it
should be used to generate bus specific macros for registering drivers like
the module_platform_driver macro.

driver core: Add ability for arch code to setup pdev_archdata

2011-07-08T05:21:35+00:00

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"

The platform_bus_set_pm_ops() operation is deprecated in favor of the
new device power domain infrastructre implemented in commit

PM: Export platform bus type's default PM callbacks

2011-04-28T22:36:05+00:00

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.

mfd: Fetch cell pointer from platform_device->mfd_cell

2011-04-12T09:13:00+00:00

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

2010-10-22T17:16:42+00:00

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.
