Document "renesas,can-r8a7743" and "renesas,can-r8a7745" compatible strings. Since the fallback compatible string ("renesas,rcar-gen2-can") activates the right code in the driver, no driver change is needed.

2016-02-26can: rcar: add device tree support for r8a779[234]Simon Horman1-0/+3
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.

2016-02-26can: rcar: add gen[12] fallback compatibility stringsSimon Horman1-1/+7
Add fallback compatibility string for R-Car Gen 1 and Gen2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, e.g. Gen 1 and Gen 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7779 is older than r8a7778 but that doesn't imply that the latter is a descendant of the former or vice versa. We can, however, by examining the documentation and behaviour of the hardware at run-time observe that the current driver implementation appears to be compatible with the IP blocks on SoCs within a given generation. For the above reasons and convenience when enabling new SoCs a per-generation fallback compatibility string scheme being adopted for drivers for Renesas SoCs.
