dm: Adjust lists_bind_fdt() to return the bound device

2014-09-10T18:59:59+00:00

Allow the caller to find out the device that was bound in response to this
call.

dm: Improve errors and warnings in lists_bind_fdt()

2014-07-23T13:08:37+00:00

Add a debug message for when a device tree node has no driver. Also reword
the warning when a device fails to bind, which was misleading.

dm: Allow drivers to be marked 'before relocation'

2014-07-23T13:07:24+00:00

Driver model currently only operates after relocation is complete. In this
state U-Boot typically has a small amount of memory available. In adding
support for driver model prior to relocation we must try to use as little
memory as possible.

In addition, on some machines the memory has not be inited and/or the CPU
is not running at full speed or the data cache is off. These can reduce
execution performance, so the less initialisation that is done before
relocation the better.

An immediately-obvious improvement is to only initialise drivers which are
actually going to be used before relocation. On many boards the only such
driver is a serial UART, so this provides a very large potential benefit.

Allow drivers to mark themselves as 'pre-reloc' which means that they will
be initialised prior to relocation. This can be done either with a driver
flag or with a 'dm,pre-reloc' device tree property.

To support this, the various dm scanning function now take a 'pre_reloc_only'
parameter which indicates that only drivers marked pre-reloc should be
bound.

dm: add missing includes

2014-07-18T21:53:23+00:00

lists.c / root.c do not include their own header and they
could potentially implement a different function. Therefore
actually include the headers.

dm: Add missing header files in lists and root

2014-06-20T17:55:42+00:00

These files don't compile in some architectures. Fix it by adding the
missing headers.

dm: Rename struct device_id to udevice_id

2014-06-20T17:55:18+00:00

It is best to avoid having any occurence of 'struct device' in driver
model, so rename to achieve this.

dm: rename device struct to udevice

2014-05-27T14:21:32+00:00

using UBI and DM together leads in compiler error, as
both define a "struct device", so rename "struct device"
in include/dm/device.h to "struct udevice", as we use
linux code (MTD/UBI/UBIFS some USB code,...) and cannot
change the linux "struct device"

dm: Add base driver model support

2014-03-04T17:15:29+00:00

Add driver model functionality for generic board.

This includes data structures and base code for registering devices and
uclasses (groups of devices with the same purpose, e.g. all I2C ports will
be in the same uclass).

The feature is enabled with CONFIG_DM.
