Subject: [PATCH V2 3/3] arm64: dts: add initial device tree for Thunder Bay SoC
Date: Tue, 20 Jul 2021 10:52:49 +0530	[thread overview]
Message-ID: <1626758569-27176-4-git-send-email-kenchappa.demakkanavar@intel.com> (raw)
In-Reply-To: <1626758569-27176-1-git-send-email-kenchappa.demakkanavar@intel.com>

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

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)
