Hmm? While I see plenty of usb errata (mostly DMA bugs), I don't see anything about registers being different. I do see something curious: advisory 70, the only PHY-related erratum I see, is also present in the DM814x errata and even in AM335x r1.0. This strongly suggests the PHYs must at least be closely related... The dm816x TRM makes three separate mentions of the synopsys usb phy though, while I found no other TRMs that mention it, so if it's a copy-paste error (which certainly would not be exceptional) I don't know where from. I suppose it's still possible TI acquired a sufficiently permissive license for the synopsys phy to fork it and call it a "TI PHY" as they do in the AM335x docs. (No mention of its origin is made in the DM814x docs.) BTW, da850? Is that yet another instance of Primus? (i.e. omap-L1xx/c674x/am1xxx with odd final digit, also da830/da828) Matthijs -- To unsubscribe from this list: send the line "unsubscribe linux-omap" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
