drivers: core: device: add support to check dt compatible for a device/machine

2016-05-24T16:42:02+00:00

Provide an api to check whether the given device or machine is
compatible with the given compat string which helps in making
decisions in drivers based on device or machine compatible.

Idea taken from Linux.

dm: core: Allow device names to be freed automatically

2016-05-17T15:54:43+00:00

Some devices have a name that is stored in allocated memory. At present
there is no mechanism to free this memory when the device is unbound.

Add a device flag to track whether a name is allocated and a function to
add the flag. Free the memory when the device is unbound.

dm: core: Add dev_get_addr_ptr() to return a pointer to the reg address

2016-04-25T05:30:16+00:00

On some platforms (e.g. x86), the return value of dev_get_addr() can't
be assigned to a pointer type variable directly. As there might be a
difference between the size of fdt_addr_t and the pointer type. On
x86 for example, "fdt_addr_t" is 64bit but "void *" only 32bit. So
assigning the register base directly in dev_get_addr() results in this
compilation warning:
  warning: cast to pointer from integer of different size

This patch introduces the new function dev_get_addr_ptr() that
returns a pointer to the 'reg' address that can be used by drivers
in this case.

fdt: implement dev_get_addr_name()

2016-04-15T14:14:37+00:00

This function parses the reg property based on an index found in the
reg-names property. This is required for bindings that are written
using reg-names rather than hard-coding indices in reg.

dm: core: Add option to configure an offset for the address translation

2016-01-12T17:19:09+00:00

Some platforms need to ability to configure an offset to the standard
addresses extracted from the device-tree. This patch allows this by
adding a function to DM to configure this offset (if needed).

dm: core: Tidy up devres comments

2015-10-23T15:42:28+00:00

Adjust the devres comments to be consistent with the rest of the file, and
add one for the struct udevice member. Also rename the 'p' parameter to
'ptr' to avoid single-character names.
