dm: core: Add \n to two dm_warn() messages

2015-07-21T23:39:38+00:00

These should finish with a newline like the others.

dm: do not set DM_FLAG_ACTIVATED twice

2015-07-21T23:39:34+00:00

Currently, DM_FLAG_ACTIVATED is set twice; before calling
uclass_pre_probe_device() and again before calling drv->probe().

It looks like Simon's intention is the first one.
The DM_FLAG_ACTIVATED was moved twice, by commit 02eeb1bbb174
(dm: core: Mark device as active before calling its probe()
method), and then by commit 206d4d2b4b30 (dm: core: Mark device
as active before calling uclass probe() methods).
The first marking was added by the last move.

dm: core: Correct device_get_child_by_of_offset() parameter

2015-07-21T23:39:23+00:00

This parameter is named 'seq' but should be named 'of_offset'.

dm: core: Add a function to find any device from device tree

2015-07-21T23:39:22+00:00

In some rare cases it is useful to be able to locate a device given a device
tree node offset. An example is when you have an alias that points to a node
and you want to find the associated device. The device may be SPI, MMC or
something else, but you don't need to know the uclass to find it.

Add a function to do a global search for a device, given its device tree
offset.

dm: core: drop device removal error path correctly

2015-04-28T22:49:02+00:00

Trivial bug fix for commit 5a87c4174d18 (dm: core: Drop device
removal error path when not supported).

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()
