From 87027292c102ca5371be62e52f6a73aeca9b3da0 Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Tue, 21 Jul 2020 20:54:38 +0530 Subject: [PATCH] ARM: dts: rockchip: Add USB for RockPI N8/N10 Radxa dalang carrier board has 2x USB 2.0 and 1x USB 3.0 ports. This patch adds support to enable all these USB ports for N10 and N8 combinations SBCs. Note that the USB 3.0 port on RockPI N8 combination works as USB 2.0 OTG since it is driven from RK3288.
