Subject: [PATCH] ARM: imx: ehci: fix host power mask bit
Date: Fri, 16 Nov 2012 15:39:24 +0100 [thread overview]
Message-ID: <1353076764.3647.35.camel@mars> (raw)
In-Reply-To: <20121116142531.228251f6@eb-e6520>
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.
