* Revert "dm: ns16550: Add support for reg-offset property"Tom Rini2016-02-29-4/+2
| | | | | | | | | | | This reverts commit d9a3bec682f9756621615f4306718a356a3230e3. While this is a correct change to do long term it unfortunately breaks a number of platforms that are using pdata and not named struct members so they are getting all of their data after 'base' incorrect.

* serial: dcc: Move driver to DMMichal Simek2016-02-25-25/+49
| | | | | | | | | | | | | | | | | | | | | | Enabling this driver requires some DT changes. Adding DCC to root or main bus: dcc: dcc { compatible = "arm,dcc"; u-boot,dm-pre-reloc; }; Extend alias list to link DCC: serial0 = &uart0; serial1 = &uart1; serial2 = &dcc; Change stdout-path to point to dcc port. stdout-path = "serial2:115200n8"; Also add support for debug uart to help with early debug.
