dm: core: device: add function: dev_get_uclass_name()

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

This commit extends the driver model device's API by function:
- dev_get_uclass_name()

And this function returns the device's uclass driver name if:
- given dev pointer, is non_NULL
otherwise, the NULL pointer is returned.

dm: core: device: add function: dev_get_driver_ops()

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

This commit extends the driver model device's API by function:
- dev_get_driver_ops()

And this function returns the device's driver's operations if given:

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: Rename driver data function to dev_get_driver_data()

2015-04-18T17:11:19+00:00

The existing get_get_of_data() function provides access to both the driver's
compatible string and its driver data. However only the latter is actually
useful. Update the interface to reflect this and fix up existing users.

dm: core: Convert driver_bind() to use const

2015-04-18T17:11:19+00:00

The driver is not modified by driver model, so update driver_bind() to
recognise that.

dm: core: Support allocating driver-private data for DMA

2015-04-18T17:11:19+00:00

Some driver want to put DMA buffers in their private data. Add a flag
to tell driver model to align driver-private data to a cache boundary so
that DMA will work correctly in this case.

dm: core: Add dev_get_uclass_priv() to access uclass private data

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

Add a convenience function to access the private data that a uclass stores
for each of its devices. Convert over most existing uses for consistency
and to provide an example for others.
