parentcan: rcar: add gen[12] fallback compatibility strings (diff)
can: rcar: add device tree support for r8a779[234]
Simply document new compatibility string. As a previous patch adds a generic R-Car Gen2 compatibility string there appears to be no need for a driver updates. By documenting these compat stings they may be used in DTSs shipped, for example as part of ROMs. They must be used in conjunction with the Gen2 fallback compat string. At this time there are no known differences between the r8a779[234] IP blocks and that implemented by the driver for the Gen2 fallback compat string. Thus there is no need to update the driver as the use of the Gen2 fallback compat string will activate the correct code in the current driver while leaving the option for r8a779[234]-specific driver code to be activated in an updated driver should the need arise.
