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. In patch series v1/v2, the stub clock driver simply writes request in sram and send ipc to firmware; For patch series v3, the firmware has been upgraded to use mailbox, so stub clock driver will call standard mailbox APIs to request mailbox channel and send message to firmware. Patch 4 adds stub clock node into dts and it references mailbox with phandle, so patch 4 will depend on mailbox driver's patch series [1]. These patches have been tested on 96board hikey and is used by cpufreq driver.The To: list is everyone, so I'm not sure who is supposed to apply these patches. I'd like to take patches 1, 2, and 3 through the clk tree though.
Thanks, you could take first three patches. For patch 4, i will re-send it after mailbox driver's patches have been merged. Wei Xu, is this okay for you? Thanks, Leo Yan
