There's no need to explicitly check for data and resources being NULL,
as platform_device_add_{data,resources}() do this internally nowadays.
This makes the code more linear and less indented.

Some users of platform_device_add_{data,resources}() assume that
NULL data and resources will be handled specially, i.e. just ignored.
But the platform core ends up calling kmemdup(NULL, 0, ...), which
returns a non-NULL result (i.e. ZERO_SIZE_PTR), which causes drivers
to oops on a valid code, something like:
if (platform_data)
stuff = platform_data->stuff;
This patch makes the platform core a bit more safe for such cases.

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.

In theory (although not *yet* in practice), a driver being passed
to platform_driver_probe might have driver.bus set to something
other than platform_bus_type. Locking drv->driver.bus is always

The current code allocates and manages platform_devices created from
the device tree manually. It also uses an unsafe shortcut for
allocating the platform_device and the resource table at the same
time. (which I added in the last rework; sorry).
This patch refactors the code to use platform_device_alloc() for
allocating new devices. This reduces the amount of custom code
implemented by of_platform, eliminates the unsafe alloc trick, and has
the side benefit of letting the platform_bus code manage freeing the
device data and resources when the device is freed.

of_platform_bus was being used in the same manner as the platform_bus.
The only difference being that of_platform_bus devices are generated
from data in the device tree, and platform_bus devices are usually
statically allocated in platform code. Having them separate causes
the problem of device drivers having to be registered twice if it
was possible for the same device to appear on either bus.
This patch removes of_platform_bus_type and registers all of_platform
bus devices and drivers on the platform bus instead. A previous patch
made the of_device structure an alias for the platform_device structure,
and a shim is used to adapt of_platform_drivers to the platform bus.
After all of of_platform_bus drivers are converted to be normal platform
drivers, the shim code can be removed.

When runtime PM for platform_bus was added, it allowed for platforms
to customize the runtime PM methods since they are defined as weak

This patch allows platforms to also extend the system PM methods with

The early dev_name() setup needs to do an allocation which can only be
satisfied under slab_is_available() conditions. Some of the early
platform drivers may be initialized before this point, and those still
need to contend themselves with an empty dev_name.
This fixes up a regression with the SH earlyprintk which was bailing out
prior to hitting the early probe path due to not being able to satisfy
the early allocation. Other early platform drivers (such as the early
timers) that need to match the dev name are sufficiently late that
allocations are already possible.

Currently the default runtime PM callbacks for platform devices return
-ENOSYS, preventing the use of runtime PM platforms until they have
provided at least a default implementation. This hinders the use of
runtime PM by devices which work with many platforms such as memory
mapped devices, MFDs and on chip IPs shared by multiple architectures.
Change the default implementation to the standard pm_generic_runtime
one, allowing drivers to use runtime PM without per-architecture
changes.

Presently early platform devices suffer from the fact they are unable to
use dev_xxx() calls early on due to dev_name() and others being
unavailable at the time ->probe() is called.
This implements early init_name construction from the matched name/id
pair following the semantics of the late device/driver match. As a
result, matched IDs (inclusive of requested ones) are preserved when the
handoff from the early platform code happens at kobject initialization
time.
Since we still require kmalloc slabs to be available at this point, using
kstrdup() for establishing the init_name works fine. This subsequently
needs to be tested from dev_name() prior to the init_name being cleared
by the driver core. We don't kfree() since others will already have a
handle on the string long before the kobject initialization takes place.
This is also needed to permit drivers to use the clock framework early,
without having to manually construct their own device IDs from the match
id/name pair locally (needed by the early console and timer code on sh
and arm).

Commit 783ea7d4eeefe895f2731fe73ac951e94418927b
(Driver Core: Rework platform suspend/resume, print warning)
added a warning message printed for platform drivers that use the
legacy PM callbacks rather than struct dev_pm_ops. Unfortunately,
this resulted in some confusion and made some people try to convert
drivers by replacing the old callbacks with struct dev_pm_ops in
automatic way, which generally is not a good idea.
Remove the platform device runtime dev_pm_ops warning for now,
because it's annoying to users and it's not really necessary right
now.

2. Other kind of devices do not need to use platform_data, we can

Taking into consideration of thousands of files to be fixed and they
can't be finished in one night(maybe it will take a long time), so we
keep platform_data in device to allow two kind of cases coexist until
all platform devices pass its platfrom data from

V3 of the early platform driver implementation.
Platform drivers are great for embedded platforms because we can separate
driver configuration from the actual driver. So base addresses,
interrupts and other configuration can be kept with the processor or board
code, and the platform driver can be reused by many different platforms.
For early devices we have nothing today. For instance, to configure early
timers and early serial ports we cannot use platform devices. This
because the setup order during boot. Timers are needed before the
platform driver core code is available. The same goes for early printk
support. Early in this case means before initcalls.
These early drivers today have their configuration either hard coded or
they receive it using some special configuration method. This is working
quite well, but if we want to support both regular kernel modules and
early devices then we need to have two ways of configuring the same
driver. A single way would be better.
The early platform driver patch is basically a set of functions that allow
drivers to register themselves and architecture code to locate them and
probe. Registration happens through early_param(). The time for the
probe is decided by the architecture code.
See Documentation/driver-model/platform.txt for more details.

Now platform_device is being widely used on SoC processors where the
peripherals are attached to the system bus, which is simple enough.
However, silicon IPs for these SoCs are usually shared heavily across
a family of processors, even products from different companies. This
makes the original simple driver name based matching insufficient, or
simply not straight-forward.
Introduce a module id table for platform devices, and makes it clear
that a platform driver is able to support some shared IP and handle
slight differences across different platforms (by 'driver_data').
Module alias is handled automatically when a MODULE_DEVICE_TABLE()
is defined.
To not disturb the current platform drivers too much, the matched id
entry is recorded and can be retrieved by platform_get_device_id().

PM: Simplify the new suspend/hibernation framework for devices
Following the discussion at the Kernel Summit, simplify the new
device PM framework by merging 'struct pm_ops' and
'struct pm_ext_ops' and removing pointers to 'struct pm_ext_ops'
from 'struct platform_driver' and 'struct pci_driver'.
After this change, the suspend/hibernation callbacks will only
reside in 'struct device_driver' as well as at the bus type/
device class/device type level. Accordingly, PCI and platform
device drivers are now expected to put their suspend/hibernation
callbacks into the 'struct device_driver' embedded in
'struct pci_driver' or 'struct platform_driver', respectively.
