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