   4 Subject: [PATCH] arm64: dts: qcom: add PMP8074 DTSI
   5
   6 PMP8074 is a companion PMIC to the Qualcomm IPQ8074 series that is
   7 controlled via SPMI.
   8
   9 Add DTSI for it providing GPIO, regulator, RTC and VADC support.
  10
  11 RTC is disabled by default as there is no built-in battery so it will
  12 loose time unless board vendor added a battery, so make it optional.
