dm: define dev_*() log functions in DM header

2017-10-04T16:00:20+00:00

Many drivers had started to use dev_err, dev_info, etc. for log
functions.  Currently, we are relying on , but I
guess the best home is , taking into account that
Linux defines them in .

For now, I am leaving the ones in  because lots of
Linux-originated code uses dev_*(), but the first argument is not
struct udevice, so we need to ignore the bogus argument.  More
efforts are needed to iron out the issues.

dm: core: Rename of_device_is_compatible()

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

The of_ prefix conflicts with the livetree version of this function.
Rename it to avoid problems when we add livetree support.

dm: core: Add ofnode to represent device tree nodes

2017-06-01T13:03:04+00:00

With live tree we need a struct device_node * to reference a node. With
the existing flat tree, we need an int offset. We need to unify these into
a single value which can represent both.

Add an ofnode union for this and adjust existing code to move to this.

dm: core: Move dev_get_addr() etc. into a separate file

2017-06-01T12:57:52+00:00

Move this group of address-related functions into a new file. These use
the flat device tree. Future work will provide new versions of these which
can support the live tree.

dm: core: Add DM_FLAG_OS_PREPARE flag

2017-05-17T09:13:06+00:00

This new flag can be added to DM device drivers, which need to do some
final configuration before U-Boot exits and the OS (e.g. Linux) is
started. The remove functions of those drivers will get called at
this stage to do these last-stage configuration steps.

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 dev_get_addr_size_index() to retrieve addr and size

2016-12-03T04:03:31+00:00

The currently available functions accessing the 'reg' property of a
device only retrieve the address. Sometimes its also necessary to
retrieve the size described by the 'reg' property. This patch adds
the new function dev_get_addr_size_index() which retrieves both,
the address and the size described by the 'reg' property.

dm: core: Add a function to bind child devices

2016-07-27T20:14:37+00:00

We currently use dm_scan_fdt_node() to bind devices. It is an internal
function and it requires the caller to know whether we are pre- or post-
relocation.

This requirement has become quite common in drivers, so the current function
is not ideal.

Add a new function with fewer arguments, that does not require internal
headers. This can be used directly as a post_bind() method if needed.

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.
