From 4b0446d57fb015f329d4b8f71c71b19999f066cd Mon Sep 17 00:00:00 2001 From: Jagan Teki Date: Tue, 21 Jul 2020 20:54:37 +0530 Subject: [PATCH] ARM: dts: rockchip: Add usb host0 ohci node for rk3288 rk3288 and rk3288w have a usb host0 ohci controller. Although rk3288 ohci doesn't actually work on hardware, but rk3288w ohci can work well. So add usb host0 ohci node in rk3288 dtsi and the quirk in ohci platform driver will disable ohci on rk3288.
