[PATCH v2 0/5] clk: hisilicon: support stub clock

This series adds support for hisilicon stub clock driver. 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
