Message-Id: <20240506-eyeq6h-v1-3-f29b5269cc43@bootlin.com> Date: Mon, 06 May 2024 18:16:12 +0200 From: Gregory CLEMENT <gregory.clement@...tlin.com> To: Vladimir Kondratiev <vladimir.kondratiev@...ileye.com>, Théo Lebrun <theo.lebrun@...tlin.com>, Thomas Bogendoerfer <tsbogend@...ha.franken.de>, Rob Herring <robh@...nel.org>, Krzysztof Kozlowski <krzk+dt@...nel.org>, Conor Dooley <conor+dt@...nel.org> Cc: linux-mips@...r.kernel.org, devicetree@...r.kernel.org, linux-kernel@...r.kernel.org, Tawfik Bayouk <tawfik.bayouk@...ileye.com>, Thomas Petazzoni <thomas.petazzoni@...tlin.com>, Alexandre Belloni <alexandre.belloni@...tlin.com>, Gregory CLEMENT <gregory.clement@...tlin.com> Subject: [PATCH 3/3] MIPS: mobileye: Add EyeQ6H support EyeQ6H (or “High”) is an other SoC from Mobileye still based on the MIPS I6500 architecture as the EyeQ5. The 2 clusters of this SoC contains 4 cores which are capable of running 4 threads. Besides this, it features multiple controllers such as the classic UART, high speed I2C, SPI, as well as CAN-FD, PCIe Gen4, Octal/Quad SPI Flash interface, Gigabit Ethernet, MIPI CSI-2, MIPI DSI, and eMMC 5.1. It also includes a Hardware Security Module, Functional Safety Hardware, and video encoders and more. This commit provides the infrastructure to build a kernel running on EyeQ6H SoC. For now the support is limited and only one CPU core is running.
