dm: core: Add a way to find a device by ofnode

2017-06-01T13:03:08+00:00

Add a function which looks up a device by its node (either in live tree
or flat tree).

core/uclass: Print name of device in uclass_find_device_by_seq()

2017-04-13T20:44:49+00:00

uclass_find_device_by_seq() prints seq and req_seq when debugging is
enabled, but this information is not very useful by itself. Add the
name of he driver to this information. This improves debugging as it
shows which devices are being considered.

dm: core: Add flags parameter to device_remove()

2017-04-05T02:15:10+00:00

This patch adds the flags parameter to device_remove() and changes all
calls to this function to provide the default value of DM_REMOVE_NORMAL
for "normal" device removal.

This is in preparation for the driver specific pre-OS (e.g. DMA
cancelling) remove support.

dm: core: Replace of_offset with accessor

2017-02-08T13:12:14+00:00

At present devices use a simple integer offset to record the device tree
node associated with the device. In preparation for supporting a live
device tree, which uses a node pointer instead, refactor existing code to
access this field through an inline function.

dm: core: Add a function to get a uclass name

2016-10-11T03:55:33+00:00

It is useful in debug() statements to display the name of the uclass for a
device. Add a simple function to provide this.

dm: core: Add a way to find a device by its driver

2016-07-26T02:46:43+00:00

Some SoCs have a single clock device. Provide a way to find it given its
driver name. This is handled by the linker so will fail if the name is not
found, avoiding strange errors when names change and do not match. It is
also faster than a string comparison.

dm: core: Add uclass_first_device_err() to return a valid device

2016-03-14T21:34:50+00:00

A common pattern is to call uclass_first_device() and then check if it
actually returns a device. Add a new function which does this, returning
an error if there are no devices in that uclass.

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: 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.
