From 6ac1d1532c888b030acb3b4ac82425448cb15198 Mon Sep 17 00:00:00 2001 From: Simon Horman Date: Tue, 11 Jul 2017 13:44:20 +0200 Subject: ata: sata_rcar: add gen[23] fallback compatibility strings Add fallback compatibility string for R-Car Gen 2 and 3. In the case of Renesas R-Car hardware we know that there are generations of SoCs, e.g. 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 being adopted for drivers for Renesas SoCs.
