LF-191-2 i2c: introduce xen i2c paravirtualization driver Add i2c backend frontend support. The transaction only support one msg each time. The frontend sends a request to backend, backend use i2c_transfer to do real transaction to hardware and return the results to frontend. Now i2cdump/get/set works. In domu cfg file, use "vi2c = ['backend=0,be-adapter=5a800000.i2c,addr=0x51;0x44']" to create a dummy controller in frontend and allowed slaves in backend. Currently the slave address check not added, it will be supported in furture patch. Signed-off-by: Peng Fan <peng.fan@nxp.com> Acked-by: Leonard Crestez <leonard.crestez@nxp.com>
