dm: core: allow device_bind() to not return a device pointer

2015-08-31T13:57:29+00:00

This is useful when we want to bind a device, but do not need the
pointer to the device.

dm: core: Add a function to bind a driver for a device tree node

2015-04-30T03:02:32+00:00

Some device tree nodes do not have compatible strings but do require
drivers. This is pretty rare, and somewhat unfortunate. Add a function
to permit creation of a driver for any device tree node.

dm: Add a function to bind a device by driver name

2014-11-22T09:16:47+00:00

In some cases we need to manually bind a device to a particular driver.
Add a function to do this.

dm: fix comments

2014-10-22T16:32:16+00:00

The struct udevice stands for a device, not a driver.
The driver_info.name is a driver's name, which is referenced
to bind devices.

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: 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: Tidy up four minor code nits

2014-06-20T17:56:50+00:00

There is a spelling mistake and two functions are missing comments
altogether. Also the flags declaration is correct, but doesn't follow
style. Finally, the uclass_get_device() function has some errors in
its documentation.

Fix these problems.

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.
