[PATCH v1 00/16] arm: xea: Update i.MX28 XEA board to use DM_SERIAL

[Lukasz Majewski]

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
