The Turing RK1 is an upcoming RK3588-based SoM from Turing Machines, designed on the Jetson SO-DIMM form factor and meant to be compatible with most Jetson carrier boards (but especially the Turing Pi 2 cluster board from the same vendor). It has the typical I/O you'd expect from a Jetson board, including: - Two UARTs (UART9 for console, UART2 is auxiliary) - PCI Express (2.0 x1 + 3.0 x4) - Gigabit Ethernet - On-board eMMC - PWM fan w/ tach - USB-OTG [1] - HDMI and MIPI DSI [1] - Miscellaneous external GPIO, I²C, SPI lines [1] Beyond that, it is pretty similar to the RK3588 EVB (in terms of PMICs, RTC, etc). While this is absolutely a SoM, it is a little bit special in that it's marketed directly to users as a compute node, while most SoMs are intended to be a part/module incorporated into a larger system. Because of this, a majority of the users will be treating the RK1 less like a SoM and more like a miniature "blade server." This patch introduces a dtsi to enable most[1] of the SoM I/O, as well as a dts catered more directly to the "compute node" use case. [1] These peripherals are not addressed with this patch.
