[PATCH v3 3/3] arm64: dts: add initial device tree for Thunder Bay SoC

From: kenchappa . demakkanavar
Date: Thu Sep 16 2021 - 01:58:44 EST


From: "Kenchappa, Demakkanavar" <kenchappa.demakkanavar@xxxxxxxxx>

Add initial device tree for Intel Movidius SoC code-named Thunder Bay.

This initial DT includes nodes for 4 CPU clusters with 4 Cortex-A53
cores per cluster, UARTs, GIC, ARM Timer and PSCI.

thunderbay-soc.dtsi - Thunder Bay SoC dtsi file
hddl_hybrid_4s.dts - Thunder Bay full configuration board dts
with 4 VPU processors
hddl_hybrid_2s_02.dts - Thunder Bay prime configuration board dts with
2 VPU processors (slice 0 and slice 2 enabled)
hddl_hybrid_2s_03.dts - Thunder Bay prime configuration board dts with
2 VPU processors (slice 0 and slice 3 enabled)
hddl_hybrid_2s_12.dts - Thunder Bay prime configuration board dts with
2 VPU processors (slice 1 and slice 2 enabled)
hddl_hybrid_2s_13.dts - Thunder Bay prime configuration board dts with
2 VPU processors (slice 1 and slice 3 enabled)
