   4 Subject: [PATCH 2/2] cpufreq: qcom-nvmem: Introduce cpufreq for ipq95xx
   5
   6 IPQ95xx SoCs have different OPPs available for the CPU based on
   7 the SoC variant. This can be determined from an eFuse register
   8 present in the silicon.
   9
  10 Added support for ipq95xx on nvmem driver which helps to
  11 determine OPPs at runtime based on the eFuse register which
  12 has the CPU frequency limits. opp-supported-hw dt binding
  13 can be used to indicate the available OPPs for each limit.
