[PATCH v7 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 info.

Driver has been validated on Bubblegum-96 board.

Thanks,
Mani

Changes in V7:

* Fixed gate clock function naming issue reported by Kbuild bot

Changes in V6: (https://lkml.org/lkml/2018/3/17/43)

* Fixed warnings generated by Kbuild bot
* Reused generic fixed factor clk ops for owl-fixed-factor.c
* Moved S900 register definitions to owl-s900.c
* Dropped dt-bindings since it got applied
* Addressed Stephen's comments on whole

Changes in V5:

* Changed I2C clocks to fixed factor clocks
* Fixed minor issue in S900 PLL clock names
* Fixed S900 Kconfig
* Rebased on top of 4.16-rc5

Changes in V4:

* Moved to SPDX license tag for dt-bindings
* Fixed a warning in owl-common.h
* Rebased on top of 4.16-rc3

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
