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