Merge tag 'arm-soc/for-4.15/drivers-part2' of http://github.com/Broadcom/stblinux into next/drivers
Pull "Broadcom drivers changes for 4.15 (part 2)" from Florian Fainelli:
This pull request contains Broadcom ARM/ARM64/MIPS SoCs changes for 4.15
(second part), please pull the following:
- Markus updates the Broadcom STB DPFE driver to avoid loading the firmware when
unnecessary to accomodate for specific platform restrictions
- Florian adds support for the Broadcom Hurricane 2 SoC iProc PLL clock needed
to get the proper CPU clock frequency
* tag 'arm-soc/for-4.15/drivers-part2' of http://github.com/Broadcom/stblinux:
clk: bcm: Add Broadcom Hurricane 2 clock support
memory: brcmstb: dpfe: skip downloading firmware when possible
memory: brcmstb: dpfe: introduce is_dcpu_enabled()
