Merge branch 'ns2-amac'
Jon Mason says: ==================== add NS2 support to bgmac Changes in v6: * Use a common bgmac_phy_connect_direct (per Rafal Milecki) * Rebased on latest net-next * Added Reviewed-by to the relevant patches Changes in v5: * Change a pr_err to netdev_err (per Scott Branden) * Reword the lane swap binding documentation (per Andrew Lunn) Changes in v4: * Actually send out the lane swap binding doc patch (Per Scott Branden) * Remove unused #define (Per Andrew Lunn) Changes in v3: * Clean-up the bgmac DT binding doc (per Rob Herring) * Document the lane swap binding and make it generic (Per Andrew Lunn) Changes in v2: * Remove the PHY power-on (per Andrew Lunn) * Misc PHY clean-ups regarding comments and #defines (per Andrew Lunn) This results on none of the original PHY code from Vikas being present. So, I'm removing him as an author and giving him "Inspired-by" credit. * Move PHY lane swapping to PHY driver (per Andrew Lunn and Florian Fainelli) * Remove bgmac sleep (per Florian Fainelli) * Re-add bgmac chip reset (per Florian Fainelli and Ray Jui) * Rebased on latest net-next * Added patch for bcm54xx_auxctl_read, which is used in the BCM54810 ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
