[PATCH v2 00/14] net: ldpaa_eth: transition to CONFIG_DM_ETH

> 
> This patch set targets to add support for CONFIG_DM_ETH in DPAA2 based
> SoCs. We start by adding a DM MDIO driver for the MDIO interface found on the
> mEMAC. The next two patches start the transition of the ldpaa_eth and fsl-mc

Hi Priyanka,

Any feedback regarding this series that I can act on?
