   4 Subject: [PATCH] cpufreq: qcom-nvmem: add support for IPQ8074
   5
   6 IPQ8074 comes in 3 families:
   7 * IPQ8070A/IPQ8071A (Acorn) up to 1.4GHz
   8 * IPQ8172/IPQ8173/IPQ8174 (Oak) up to 1.4GHz
   9 * IPQ8072A/IPQ8074A/IPQ8076A/IPQ8078A (Hawkeye) up to 2.2GHz
  10
  11 So, in order to be able to share one OPP table lets add support for IPQ8074
  12 family based of SMEM SoC ID-s as speedbin fuse is always 0 on IPQ8074.
  13
  14 IPQ8074 compatible is blacklisted from DT platdev as the cpufreq device
  15 will get created by NVMEM CPUFreq driver.
