[PATCH v3 00/11] Add clock driver for Actions S900 SoC

[Manivannan Sadhasivam]

This patchset adds clock support for Actions Semi OWL series
S900 SoC with relevant clock bindings and device tree data.

Driver has been validated on Bubblegum-96 board.

Thanks,
Mani

Changes in V3:

* Completely refactored the clock driver based on sunxi-ng
  clock structure
* Removed all owl_ prefixed functions for registering the
  clock driver and used the registration functions directly
* Moved to SPDX based license tag
* Removed module dependencies from the driver
* Made I2C clocks as simple gate clocks due to the lack of
  information about factor rates
* Added Ack from Rob for DT bindings
* Sourced CMU clock for UART5

Changes in V2: (https://lkml.org/lkml/2017/11/6/840)

* Changed the directory structure to actions/ and used owl- prefix
  for sources.
* Fixed MAINTAINERS and added Andreas as Designated Reviewer (R:).
* Introduced new Kconfig for S900 code part (CONFIG_CLK_OWL_S900).
* Changed the license from GPLv2 to GPLv2+.
* Moved fixed clock sources to DT
* Changed clock-controller node name to cmu in DT
* Added clocks property to cmu node in DT
* Changed compatible property value to "actions,s900-cmu"
* Fixed example UART controller node in documentation
* Fixed tab vs space issue

Changes in V1: (https://lkml.org/lkml/2017/10/31/808)

* Addressed last year's review comments from Stephen
