dm: simplify uclass_foreach_dev() implementation

2015-08-31T13:56:44+00:00

This can be simply written with list_for_each_entry(), maybe
this macro was not necessary in the first place.

dm: core: Support finding a device by phandle

2015-08-06T02:57:51+00:00

It is common for one node to reference another via a phandle. Add support
for obtaining an attached device by this method. As an example, a node may
have a 'power-supply' property which references a regulator, allowing the
driver to turn on its power.

dm: core: precise comments for get/find device by name

2015-04-22T17:03:16+00:00

The functions:
- uclass_find_device_by_name()
- uclass_get_device_by_name()
searches the required device for the exactly given name.
This patch, presice this fact for both function's comments.

dm: core: uclass: add function: uclass_get_device_by_name()

2015-04-22T17:03:15+00:00

This commit extends the driver model uclass's API by function:
- uclass_get_device_by_name()

And this function returns the device if:
- uclass with given ID, exists,
- device with exactly given name(dev->name), exists,
- device probe, doesn't return an error.

The returned device is activated and ready to use.

Note:
This function returns the first device, which name is equal
to the given one. This means, that using this function you must
assume, that the device name is unique in the given uclass's ID
device list.

dm: core: Extend struct udevice by '.uclass_platdata' field.

2015-04-22T17:03:14+00:00

This commit adds 'uclass_platdata' field to 'struct udevice', which
can be automatically allocated at bind. The allocation size is defined
in 'struct uclass_driver' as 'per_device_platdata_auto_alloc_size'.

New device's flag is added: DM_FLAG_ALLOC_UCLASS_PDATA, which is used
for memory freeing at device unbind method.

As for other udevice's fields, a complementary function is added:
- dev_get_uclass_platdata()

dm: core: Add a uclass pre_probe() method for devices

2015-04-17T01:27:42+00:00

Some uclasses want to set up a device before it is probed. Add a method
for this.

An example is with PCI, where a PCI uclass wants to set up its private
data for later use. This allows the device's uclass() method to make calls
whcih use that data (for example, read PCI memory regions from device
tree, set up bus numbers).

dm: core: Allow uclass to set up a device's child before it is probed

2015-01-30T00:09:56+00:00

Some buses need to set up their devices before they can be used. This setup
may well be common to all buses in a particular uclass. Support a common
pre-probe method for the uclass, called before any bus devices are probed.

dm: core: Allow the uclass to set up a device's child after binding

2015-01-30T00:09:56+00:00

For buses, after a child is bound, allow the uclass to perform some
processing. This can be used to figure out the address of the child (e.g.
the chip select for SPI slaves) so that it is ready to be probed.

This avoids bus drivers having to repeat the same process, which really
should be done by the uclass, since it is common.
