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: convert platform_{get,set}_drvdata to static inline functions

2011-02-18T16:15:51+00:00

This patch converts the macros for platform_{get,set}_drvdata to
static inline functions to add typechecking.

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.

Driver core: reduce duplicated code for platform_device creation

2010-08-05T20:53:34+00:00

This makes the two similar functions platform_device_register_simple
and platform_device_register_data one line inline functions using a new
generic function platform_device_register_resndata.

platform: Make platform resource input parameters const

2010-05-17T19:37:40+00:00

Make the platform resource input parameters of platform_device_add_resources()
and platform_device_register_simple() const, as the resources are copied and
never modified.

Driver core: add platform_create_bundle() helper

2010-03-08T01:04:46+00:00

Many legacy-style module create singleton platform devices themselves,
along with corresponding platform driver. Instead of replicating error
handling code in all such drivers, provide a helper that allocates and
registers a single platform device and a driver and binds them together.

Driver Core: Early platform driver buffer

2009-12-11T19:24:55+00:00

Add early_platform_init_buffer() support and update the
early platform driver code to allow passing parameters
to the driver on the kernel command line.

early_platform_init_buffer() simply allows early platform
drivers to provide a pointer and length to a memory area
where the remaining part of the kernel command line option
will be stored.

Needed to pass baud rate and other serial port options
to the reworked early serial console code on SuperH.

PM: Remove platform device suspend_late()/resume_early() V2

2009-07-21T22:28:39+00:00

This is V2 of the platform driver power management late/early
callback removal patch. The callbacks ->suspend_late() and
->resume_early() are removed since all in-tree users now have
been migrated to dev_pm_ops.
