Subject: [PATCH 1/3] ARM: dts: imx27: Use the correct usb clock gate
Date: Wed, 16 Apr 2014 14:10:15 -0300	[thread overview]
Message-ID: <1397668217-17551-1-git-send-email-festevam@gmail.com> (raw)

From: Fabio Estevam <fabio.estevam@freescale.com>

USB Host1, Host2 and OTG are gated via 'usb_ipg_gate' clock, so fix it in order
to avoid the following kernel oops:

usbcore: registered new interface driver usb-storage
10024000.usb supply vbus not found, using dummy regulator
Unhandled fault: external abort on non-linefetch (0x808) at 0xf4424184
