Subject: [PATCH 2/2] ARM: dts: imx6ull: add seeed studio NPi dev board
Date: Thu, 29 Feb 2024 13:53:37 +0530
Message-Id: <20240229082337.3090778-2-parthiban@linumiz.com>

Add support for Seed Stuidos NPi i.MX6ULL SoM equipped with
512MB RAM and 8GB eMMC or 512MB NAND flash. Development
board comes with either eMMC or NAND based SoM with peripheral
interfaces like 2 x ethernet, 2 x USB, LCD, CSI and more.
