From 356c27227b3b6aa824dcf11ffe632095e3cffe8a Mon Sep 17 00:00:00 2001 From: Richard Hu Date: Mon, 22 Jul 2019 13:27:29 +0300 Subject: [PATCH] arm64: dts: fsl: pico-pi: Add a device tree for the PICO-PI-IMX8M TechNexion PICO-PI-IMX8M-DEV evaluation and development kit based on NXP i.MX8M Quad applications processor. Datasheet can be found at: https://s3.us-east-2.amazonaws.com/technexion/datasheets/picopiimx8m.pdf The current level of support yields a working console and is able to boot userspace from NFS or init ramdisk.
