  Clock framework fixes:
   - The clk_test_freq() (aka CLK_SET_DRYRUN) doesn't change frequency,
     don't cache it result.
   - Fix busy condition for clk_set_freq().

Add clk_set_assigned

assigned-clock-parents are DT properties used to configure
some default parent clocks on one node.

  REGULATOR: Move functions for handling with regulator ranges to common file.
  They can be useful for other PMICs.

  r302523:
    Add clk_get_by_ofw_node_index, which is like clk_get_by_ofw_index but
    operates on a specific OF node instead of the pass in device's OF node.
  r302528:
    EXTRES: Add OF node as argument to all _get_by_ofw_() functions.
    In some cases, the driver must handle given properties located in specific
    OF subnode. Instead of creating duplicate set of function, add 'node' as
    argument to existing functions, defaulting it to device OF node.

Rename gpiobus_map_pin() to gpiobus_acquire_pin(), to better reflect the

2016-05-26T15:45:36+00:00

fact that the caller is requesting exclusive use of the pin, and also to
better match the inverse operation which is named gpiobus_release_pin().

Use OF_prop_free instead of direct call to free(9)

Fix support for fixed factor clocks.

2016-03-23T19:26:53+00:00

 - Use a different device description for fixed and fixed factor clocks.
 - Fix a bug where the "clock-div" property was stored in the "mult" field
   of the clock definition.
 - Get the fixed factor parent clock by index instead of by name, as a
   clock-names property is not required to be present here.
