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

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
