This patch series fixes i.MX28 based XEA board to utilize DM_SERIAL
Changes: - Patches 1-3 - fix DTS (after Linux update) to debrick XEA - Patches 4-8 - prepare XEA's DTS to support DM_SERIAL - Patches 9-11 - fixes serial_pl01x.c driver (as this driver is used by XEA, I would prefer to have this in a single patchset - otherwise board may be bricked - Patches 12-14 - XEA and imx28 generic code fixes to support DM_SERIAL with OF_PLATDATA - Patches 15-16 - config modification to support DM_SERIAL
