From bb510ddc9d3eda3d6e1276d301e923e7021e9972 Mon Sep 17 00:00:00 2001 From: Heiko Stuebner Date: Wed, 14 May 2025 17:07:43 +0200 Subject: [PATCH] arm64: dts: rockchip: add px30-cobra base dtsi and board variants Cobra are Touchscreen devices built around the PX30 SoC using a variety of display options. The devices feature an EMMC, network port, usb host + OTG ports and a 720x1280 display with a touchscreen.
