[PATCH v3 1/2] arm64: dts: qcom: ipq9574: Add common RDP dtsi file

From: Kathiravan Thirumoorthy
Date: Wed Sep 27 2023 - 02:43:46 EST

From: Anusha Rao <quic_anusha@xxxxxxxxxxx>

Add a dtsi file to include interfaces that are common
across RDPs.

Signed-off-by: Anusha Rao <quic_anusha@xxxxxxxxxxx>

---
Changes in V3:
- Fixed the indentation issue in TLMM node

Changes in V2:
- RDP418 and RDP433 supports shdc. Removed sdhc related nodes
from common dtsi and added to corresponding rdp dts.
- Moved USB and regulator related nodes to common.dtsi.
- Updated rdp454 dts to use common.dtsi.
