Add various device tree nodes to lay the groundwork for
Qualcomm ADSP Peripheral Image Loader.
Sorry, I didn't send any cover letter for v1.
Changes since v2:
- Remove empty lines from smem DT node (Stephen)
Changes since v1:
- Move hwlock DT node under root (/) (Bjorn and Andy)
- Rename smp2p-adsp to adsp-smp2p (Bjorn)
- Remove interrupt-parent property from node (Bjorn)
Bjorn Andersson (1):
arm64: dts: msm8996: Add SMEM DT nodes
Sarangdhar Joshi (3):
arm64: dts: msm8996: Add SMEM reserve-memory node
arm64: dts: msm8996: Add reserve-memory nodes
arm64: dts: msm8996: Add SMP2P and APCS nodes
