Remove SPL undefine of CONFIG_OF_CONTROL

2015-06-11T01:26:55+00:00

Allow SPL to be built with this option so that we can support device tree
control. Disable the simple bus for now in SPL. It may be needed later.

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: core: Correct bug introduced in uclass_first/next_device()

2015-04-28T22:49:03+00:00

These functions now rely on uclass_find_first/next_device() and assume that
they will either return failure (-ve error code) or a device. In fact,
coming to the end of a list is not considered failure and they return 0
in that case.

The logic to deal with this was replaced in commit acb9ca2a with just using
uclass_get_device_tail(). Add back the missing logic. This bug was
caught by unit tests but since they were broken for other reasons at the
time, this was not noticed.

dm: core: drop device removal error path correctly

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

dm: core: Select device tree control correctly for SPL

2015-04-23T15:05:54+00:00

Some boards will not use device tree for SPL even with driver model. Add
the logic to support this.

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: Remove unbind operations when not required

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

The CONFIG_DM_DEVICE_REMOVE option takes out code related to removing
devices. It should also remove the 'unbind' code since if we cannot
remove we probably don't need to unbind.

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: Handle recursive unbinding of uclass devices

2015-04-22T17:13:17+00:00

Since a device can have children in the same uclass as itself, we need
to handle unbinding carefully: we must allow that unbinding a device in a
uclass may cause another device in the same uclass to be unbound.

Adjust the code to cope.

dm: core: remove type 'static' of function uclass_get_device_tail()

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

Uclass API provides a few functions for get/find the device.
To provide a complete function set of uclass-internal functions,
for use by the drivers, the function uclass_get_device_tail()
should be non-static.
