Subject: ARM: imx: ehci: fix host power mask bit
From: Christoph Fritz <[email protected]>
commit 3d5e2abe6e265acc5e1fda810301243e9bac92b2 upstream.
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.
