[PATCH v5 0/3] add fec support for imx6q

[Shawn Guo]

This series adds imx6q enet support.  The imx6q enet is a derivative of
imx28 enet controller.  It fixes the frame endian issue found on imx28,
and adds 1 Gbps support.

Changes since v4:
 * Confirmed with design team that i.MX28 Reference Manual has an error
   on MII_SPEED formula.  FEC uses 'ref_freq / (MII_SPEED x 2)' while
   ENET-MAC uses 'ref_freq / ((MII_SPEED + 1) x 2)', so that minus one
   should really apply for just FEC_QUIRK_ENET_MAC.

Changes since v3:
 * The minus one on phy_speed should happen before left shift.

Changes since v2:
 * Refine patch #1 to get fec_reset_phy() return void

Changes since v1:
 * Fix typo pointed out by Francois Romieu
 * Drop patch #3 in the v1
 * Rebase on net-next tree

Thanks.
