[PATCH] usb: host: ohci-platform: Disable ohci for rk3288
From: Jagan Teki
Date: Thu Jul 02 2020 - 05:05:42 EST
rk3288 has usb host0 ohci controller but doesn't actually work
on real hardware but it works with new revision chip rk3288w.
So, disable ohci for rk3288.
For rk3288w chips the compatible update code is handled by bootloader.
