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.
