dm: core: Drop device removal error path when not supported

2015-04-23T15:05:52+00:00

When CONFIG_DM_DEVICE_REMOVE is not enabled, such as in SPL, we cannot
remove or unbind devices and do not expect to get errors when binding
and probing devices. So drop the error path to reduce code size.

dm: core: Allow sequence alias support to be removed for SPL

2015-04-23T15:05:51+00:00

In many cases SPL only uses a single serial port and there is no need for
alias sequence support. We will just use the serial port pointed to by
stdout-path in the /chosen node.

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:
- dev pointer, is non-NULL
- dev->driver->ops pointer, is non-NULL
in other case the, the NULL pointer is returned.

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 device children and sibling functions

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

Add some utility functions to check for children and for the last sibling in
a device's parent.

dm: core: Mark device as active before calling uclass probe() methods

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

The uclass pre-probe functions may end up calling back into the device in
some circumstances. This can fail if recursion takes place. Adjust the
ordering so that we mark the device as active early, then retract this
later if needed.

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.
