On hi6220, the bootloader needs load the firmware image and set info for OPPs; after run into kernel, the stub clock driver is used to communicate w/t firmware for cpu dynamic frequency scaling. So finally s/w will simply write request in sram and send ipc to power controller. These patches have been tested on 96board hikey and will be used by cpufreq driver. Changes from v1: * Refine parameter checking for init flow * Remove unnecessary debugging info * Modify to check spinlock pointer when register clocks Leo Yan (5): clk: hisi: refine parameter checking for init clk: hisi: add API for allocation clk data struct dt-bindings: clk: hisilicon: Document stub clock driver clk: hisi: add stub clk driver clk: hisi: add stub clock register function .../devicetree/bindings/clock/hisi,stub-clock.txt | 38 +++ drivers/clk/hisilicon/Makefile | 2 +- drivers/clk/hisilicon/clk-stub.c | 282 +++++++++++++++++++++ drivers/clk/hisilicon/clk.c | 64 ++++- drivers/clk/hisilicon/clk.h | 17 ++ include/dt-bindings/clock/hisi,stub-clock.h | 26 ++ 6 files changed, 416 insertions(+), 13 deletions(-) create mode 100644 Documentation/devicetree/bindings/clock/hisi,stub-clock.txt create mode 100644 drivers/clk/hisilicon/clk-stub.c create mode 100644 include/dt-bindings/clock/hisi,stub-clock.h -- 1.9.1 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo-u79uwXL29TY76Z2rM5mHXA@public.gmane.org More majordomo info at http://vger.kernel.org/majordomo-info.html
