   4 Subject: [PATCH] regulator: qcom_spmi: add support for HT_P600
   5
   6 HT_P600 is a LDO PMOS regulator based on LV P600 using HFS430 layout
   7 found in PMP8074 and PMS405 PMIC-s.
   8
   9 Both PMP8074 and PMS405 define the programmable range as 1.704 to 1.896V
  10 but the actual MAX output voltage depends on the exact LDO in each of
  11 the PMIC-s.
  12 Their usual voltage that they are used is 1.8V.
  13
  14 It has a max current of 600mA, voltage step of 8mV.
