As we haven't had a mainline non-rc kernel release with this in yet, we have more scope in what we can do to sort this out. What I'd suggest is: 1. change the DT compatible strings the driver has to accept both nxp,tda19988 and nxp,tda19989, and set the appropriate device in the DT file (tda19988). I'm a bit nervous about using "nxp,tda1998x" in case we're clashing with devices with different characteristics. 2. specify that the i2c reg address must exist, but not specify what it should be - leave that open. 3. assume that there's a CEC at 0x34 for these two devices. If we wish to extend support to tda998x, then we'd need to modify the driver quite a bit anyway. -- FTTC broadband for 0.8mile line: now at 9.7Mbps down 460kbps up... slowly improving, and getting towards what was expected from it. -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
