Subject: [PATCH] i.MX25 & 35 usb config bits : fix host power bit
Date: Fri, 16 Nov 2012 22:16:46 +0100	[thread overview]
Message-ID: <1353100606.3647.40.camel@mars> (raw)

This patch sets HPM (Host power mask bit) to bit 16 according to i.MX
Reference Manual. Falsely it was set to bit 8, but this controls pull-up
Impedance.
