[U-Boot] [PATCH 6/7] i2c: lpc32xx: Move definitions to header file

Tue Mar 14 15:24:44 UTC 2017


From: Liam Beguin <lbeguin at tycoint.com>

Since the lpc32xx i2c driver does not yet support the devicetree bindings,
this structure is also needed by the board file as the hardware description
is done there.
