Subject: [PATCH 6/6] ARM: imx51-zii-rdu1: Add USBH1,2 iomux configuration
Date: Sat, 25 Aug 2018 14:03:15 -0700	[thread overview]
Message-ID: <20180825210315.4661-7-andrew.smirnov@gmail.com> (raw)
In-Reply-To: <20180825210315.4661-1-andrew.smirnov@gmail.com>

Add iomux configuration for USBH1,2 to match what U-Boot (as well as
Babbage board) would configure those pads to.
