Subject: [PATCH v6 11/12] arm64: dts: qcom: add PMP8074 DTSI
Date:   Mon,  4 Jul 2022 23:24:01 +0200
Message-Id: <20220704212402.1715182-11-robimarko@gmail.com>

PMP8074 is a companion PMIC to the Qualcomm IPQ8074 series that is
controlled via SPMI.

Add DTSI for it providing GPIO, regulator and RTC 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.

Signed-off-by: Robert Marko <robimarko@gmail.com>

Changes in v6:
* Add RTC and GPIO nodes

Changes in v5:
* Remove #address-cells and #size-cells as they are not required for
regulator subnodes
