Subject: [PATCH 1/9] ARM: dts: sun7i: lamobo-r1: Fix USB-based WiFi module power
Date: Wed, 6 Jul 2016 17:10:42 +0800 [thread overview]
Message-ID: <1467796250-22010-2-git-send-email-wens@csie.org> (raw)
In-Reply-To: <1467796250-22010-1-git-send-email-wens@csie.org>
On the Lamobo R1, USB2 is connected to the RTL8192CU WiFi module.
The power enable pin is connected to PH12.
Fix the enable pin the reg_usb2_vbus.
Also disable ohci1, as the WiFi module is USB 2.0 capable.
