[PATCH 0/4] clk: hisilicon: support stub clock

[Leo Yan <leo.yan-QSEj5FYQhm4dnm+yROfE0A@public.gmane.org>]

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.

Leo Yan (4):
  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
