dm: core: remove unnecessary return condition in uclass lookup

2014-11-22T09:16:49+00:00

These conditions never happen.
 - There is no real uclass with UCLASS_INVALID id.
 - uclass never becomes NULL because ll_entry_start() always returns
   a valid pointer.

dm: core: remove unnecessary return condition in driver lookup

2014-11-22T09:16:49+00:00

The variable "drv" never becomes NULL because ll_entry_start()
always returns a valid pointer even if there are no entries.

The case "n_ents == 0" is covered by the following "for" loop.

dm: core: remove meaningless if conditional

2014-11-22T09:16:48+00:00

If the variable "ret" is equal to "-ENOENT", it is trapped at [1] and
never reaches [2].  At [3], the condition "ret != -ENOENT" is always
true.

  if (ret == -ENOENT) {                       <------------------ [1]
          continue;
  } else if (ret == -ENODEV) {
          dm_dbg("Device '%s' has no compatible string\n", name);
          break;
  } else if (ret) {                           <------------------ [2]
          dm_warn("Device tree error at offset %d\n", offset);
          if (!result || ret != -ENOENT)      <------------------ [3]
                  result = ret;
          break;
  }

dm: Add a function to bind a device by driver name

In some cases we need to manually bind a device to a particular driver.
Add a function to do this.

dm: core: Allow access to the device's driver_id data

2014-11-22T09:16:45+00:00

When the device is created from a device tree node, it matches a compatible
string. Allow access to that string and the associated data.

dm: Allow device removal features to be dropped

2014-11-21T07:13:02+00:00

For SPL we don't expect to need to remove a device. Save some code space
by dropping this feature. The board config can define
CONFIG_DM_DEVICE_REMOVE if this is in fact needed.
