From mboxrd@z Thu Jan 1 00:00:00 1970 From: mturquette@linaro.org (Mike Turquette) Date: Sat, 3 Mar 2012 00:28:57 -0800 Subject: [PATCH v5 0/4] common clk framework Message-ID: <1330763341-3437-1-git-send-email-mturquette@linaro.org> To: linux-arm-kernel@lists.infradead.org List-Id: linux-arm-kernel.lists.infradead.org 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 Patches can be pulled from: git://git.linaro.org/people/mturquette/linux.git v3.3-rc5-clkv5 v4 can be found at, http://article.gmane.org/gmane.linux.linaro.devel/8896/ v3 can be found at, http://article.gmane.org/gmane.linux.kernel/1218622 Mike Turquette (4): Documentation: common clk API clk: Kconfig: add entry for HAVE_CLK_PREPARE clk: introduce the common clock framework clk: basic clock hardware types Documentation/clk.txt | 201 +++++++ drivers/clk/Kconfig | 31 + drivers/clk/Makefile | 2 + drivers/clk/clk-divider.c | 199 +++++++ drivers/clk/clk-fixed-rate.c | 81 +++ drivers/clk/clk-gate.c | 121 ++++ drivers/clk/clk-mux.c | 114 ++++ drivers/clk/clk.c | 1323 ++++++++++++++++++++++++++++++++++++++++++ include/linux/clk-private.h | 192 ++++++ include/linux/clk-provider.h | 294 ++++++++++ include/linux/clk.h | 68 ++- 11 files changed, 2621 insertions(+), 5 deletions(-) create mode 100644 Documentation/clk.txt create mode 100644 drivers/clk/clk-divider.c create mode 100644 drivers/clk/clk-fixed-rate.c create mode 100644 drivers/clk/clk-gate.c create mode 100644 drivers/clk/clk-mux.c create mode 100644 drivers/clk/clk.c create mode 100644 include/linux/clk-private.h create mode 100644 include/linux/clk-provider.h Cc: Jeremy Kerr Cc: Thomas Gleixner Cc: Arnd Bergman Cc: Paul Walmsley Cc: Shawn Guo Cc: Richard Zhao Cc: Saravana Kannan Cc: Magnus Damm Cc: Rob Herring Cc: Mark Brown Cc: Linus Walleij Cc: Stephen Boyd Cc: Amit Kucheria Cc: Deepak Saxena Cc: Grant Likely Cc: Andrew Lunn -- 1.7.5.4
