Subject: [PATCH v5 0/4] common clk framework
Newsgroups: gmane.linux.linaro.devel
Date: Saturday 3rd March 2012 08:28:57 UTC (over 5 years ago)
From: Mike Turquette 

The common clock framework defines a common struct clk as well as an
implementation of the clk api that unifies clock operations on various
platforms and devices.

The net result is consolidation of many different struct clk definitions
and platform-specific clock framework implementations.

I consider this version merge-worthy pending ACKs from the relevant
maintainers; namely Russell, Thomas and the platform folks interested in
porting to this framework.

I would like to thank everyone who participated in the common clk
sessions at Linaro Connect and ELC; the feedback was invaluable.

Also I would like to thank Shawn Guo, Richard Zhao, Saravana Kannan and
Magnus Damm for tirelessly updating their platforms for the last few
revisions of this patch series and providng excellent feedback each
time.

Major changes since v4:
 * rolled in TGLX's comments on overall design.  We now have,
   * proper handling of root clocks and orphan clocks
   * multi-parent clocks are handled in the core
   * struct clk is shielded from struct clk_foo and vice versa
     * this is a return to the previous struct clk_hw design
 * split basic clock types out into separate files
 * split headers up by purpose
   * clk.h remains the driver-level interface
     * declarations for rate change notifiers are the only additions
   * clk-provider.h is primary header for implementing clock operations
   * clk-private.h allows for static initialization of clock data
 * validation and bug fixes
 * rebased onto Linus' v3.3-rc5 tag
