Add fallback compatibility strings for R-Car Gen 1 and 2. In the case of Renesas R-Car hardware we know that there are generations of SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship between IP blocks might be. For example, I believe that r8a7790 is older than r8a7791 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 is being adopted for drivers for Renesas SoCs. Changes since v1: * Correct typos in changelogs * Consistently use tabs for indentation in bindings document * Enhance readability of description of bindings usage Simon Horman (3): dt-bindings: net: sh_eth: add R-Car Gen[12] fallback compatibility strings net: sh_eth: rename name structures as rcar_gen[12]_* net: sh_eth: implement R-Car Gen[12] fallback compatibility strings Documentation/devicetree/bindings/net/sh_eth.txt | 14 +++++++++-- drivers/net/ethernet/renesas/sh_eth.c | 32 +++++++++++++----------- 2 files changed, 29 insertions(+), 17 deletions(-) -- 2.11.0
