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.
