   4 Subject: [PATCH] regulator: qcom_spmi: add support for HT_P150
   5
   6 HT_P150 is a LDO PMOS regulator based on LV P150 using HFS430 layout
   7 found in PMP8074 and PMS405 PMIC-s.
   8
   9 Both PMP8074 and PMS405 define the programmable range as 1.616V to 3.304V
  10 but the actual MAX output voltage depends on the exact LDO in each of
  11 the PMIC-s.
  12
  13 It has a max current of 150mA, voltage step of 8mV.
