   4 Subject: [PATCH 19/21] cpufreq: mediatek: raise proc/sram max voltage for
   5  MT8516
   6
   7 Since the upper boundary of proc/sram voltage of MT8516 is 1300 mV,
   8 which is greater than the value of MT2701 1150 mV, we fix it by adding
   9 the corresponding platform data and specify proc/sram_max_volt to
  10 support MT8516.
