Subject: [PATCH v3 0/4] cpufreq: bmips-cpufreq: Add CPUfreq driver for Broadcom's BMIPS SoCs

From: Markus Mayer <mmayer@...adcom.com>

Sorry for the new iteration. I found two more simplifications, so here
goes. Only patch 3/4 has changed.

This series adds a CPUfreq driver for the BMIPS SoCs. In the first
iteration only BMIPS5xxx SoCs are supported.

This series is based on pm/linux-next.

The series is also available at
https://github.com/mmayer/linux/tree/bmips-cpufreq-v3

Changes since v2:
  - remove local variables freq and cpu_freq in bmips_cpufreq_get()
  - assign global variable "priv" directly in bmips_cpufreq_probe()
    rather than setting driver_data and then retrieving it from there
    to set priv in bmips_cpufreq_init()

Changes since v1:
  - based on pm/linux-next rather than 4.10-rc1
  - sanitized bmips_stb_defconfig by running "make savedefconfig"; this
    also lead to an additional patch (1/4), which contains non-CPUfreq
    related updates that "make savedefconfig" performed
  - use gobal variable to store driver data rather than policy->driver_data
  - got rid of some code as a result of using said global variable
  - kzalloc -> kmalloc
  - removed policy->freq_table = NULL;
