[RESEND,v5,0/2] Cirrus Logic CS2600 clock device

Message

This patch set provides Common Clock Framework support for the latest
Cirrus Logic clocking device, the CS2600.

This device has two input clocks and three output clocks.  One of the
input clocks, the REFCLK, can be a constant reference clock input, a
crystal reference input, or not available and use the internal clock.
The second input is the CLK_IN digital clock input.

The three clock outputs are CLK_OUT, BCLK_OUT, and FSYNC_OUT.

v2 changes:
- Remove | from after "discription" in DT binding.
- Remove discription from "clocks" in DT binding.
- Change ref_clk to xti
- Clarify auxiliary clock pin
- Change DT example to not have "reg" for the bus
- Change DT example to change i2c@0 to i2c
- Remove "OUTPUT" from the clock ouputs in the dt binding include file.
- Remove AUX_OUT defines
- Use do_div when dividing u64 by a u32
- Include the dt bindings include file
- Use the includes from the dt bindings include file aux output.
- Move of_device_id and i2c_device_id tables next to i2c_driver struct.


v3 changes:
- Changed clock-names in device tree to an emum since the both clocks
  are not always required.
- Changed cirrus,aux-output-source to a string input.
- Added cirrus,clock-mode as a string input.
- Fixed ordering in DT example.
- Removed dt-bindings .h file.
- Add in_range to allow for acceptable ranges for clock rates.

v4 changes:
- Change DT discription to add more detial.
- Move reg property to keep consistant with the required list.
- Add enum to string DT inputs and change the input values to lower case.
- Change unevauatedProperties to additionalProperties
- Reove black line.

v5 changes:
- Change dt-binding to dt-bindings in commit message
- Add minItems to clocks
- Remove unneeded comments for the cirrus,aux-output-source enums
