dm: Remove device_probe_child()

2016-01-29T04:01:23+00:00

This function is not used as the use case for it did not eventuate. Remove
it to avoid confusion.

dm: syscon: Allow finding devices by driver data

2016-01-24T04:07:19+00:00

We have a way to find a regmap by its syscon driver data value. Add the same
for syscon itself.

dm: core: Display the error number when driver binding fails

2016-01-24T04:07:18+00:00

This is often -96 (-EPFNOSUPPORT) which indicates that the uclass is not
compiled in. Display the error number to make this easier to spot.

dm: core: Export uclass_find_device_by_of_offset()

2016-01-22T03:42:35+00:00

It is sometimes useful to be able to find a device before probing it,
perhaps to set up some platform data for it. Allow finding by of_offset
also.

dm: core: Don't set pinctrl for pinctrl devices

2016-01-22T03:42:34+00:00

There is sort-of race condition when a pinctrl device is probed. The pinctrl
function is called which may end up using the same device as is being
probed. This results in operations being used before the device is actually
probed.

For now, disallow pinctrl operations on pinctrl devices while probing. An
alternative solution would be to move the operation to later in the
device_probe() function (for pinctrl devices only) but this needs more
thought.

dm: core: Call uclass post_bind() after the driver's bind() method

2016-01-21T02:06:22+00:00

At present the uclass's post_bind() method is called before the driver's
bind() method. This means that the uclass cannot use any of the information
set up by the driver. Move it later in the sequence to permit this.

This is an ordering change which is always fairly major in nature. The main
impact is that devices which have children will not see them appear in their
bind() method. From what I can see, existing drivers do not look at their
children in the bind() method, so this should be safe.

Conceptually this change seems to result in a 'more correct' ordering, since
the uclass (which is broader than the device) gets the last word.

dm: core: Provide uclass_find_device_by_phandle() only when needed

2016-01-21T02:06:21+00:00

This function cannot be used unless support is enabled for device tree
control. Adjust the code to reflect that.

spl: dm: Add SPL_DM_SEQ_ALIAS config option

2016-01-13T12:20:02+00:00

The Device Model sequence alias feature is required by some Uclasses.
Instead of disabling the feature for all SPL targets allow it to be
configured.

The config option is disabled by default to reduce code size for targets
that are not interested or do not require this feature.
