Add fallback compatibility strings for rcar phy drivers. In the case of Renesas R-Car hardware we know that there are generations of SoCs, e.g. Gen 2 and Gen 3. 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 being adopted for drivers for Renesas SoCs. Changes in v3: * Added Acks * Corrected whitespace in examples Changes in v2: * Update new compatibility strings to match the preferred scheme for ordering elements * Rebase Simon Horman (2): phy: rcar-gen2: add fallback binding phy: rcar-gen3-usb2: add fallback binding Documentation/devicetree/bindings/phy/rcar-gen2-phy.txt | 8 +++++++- Documentation/devicetree/bindings/phy/rcar-gen3-phy-usb2.txt | 10 ++++++++-- drivers/phy/phy-rcar-gen2.c | 1 + drivers/phy/phy-rcar-gen3-usb2.c | 1 + 4 files changed, 17 insertions(+), 3 deletions(-) -- 2.1.4
