While at it, I read through all datasheets of existing variants of the DP83848 phy. Here is what I've found so far: +--------------+--------------+--------+-----+ | Variant | Phy ID | Note | IRQ | +--------------+--------------+--------+-----+ | DP83848H | 0x20005c90 | MINI | NO | +--------------+--------------+--------+-----+ | DP83848J | 0x20005c90 | MINI | NO | +--------------+--------------+--------+-----+ | DP83848K | 0x20005c90 | MINI | NO | +--------------+--------------+--------+-----+ | DP83848M | 0x20005c90 | MINI | NO | +--------------+--------------+--------+-----+ | DP83848T | 0x20005c90 | MINI | NO | +--------------+--------------+--------+-----+ | DP83848EP | 0x20005c90 | | YES | +--------------+--------------+--------+-----+ | DP83848HT | 0x20005c90 | | YES | +--------------+--------------+--------+-----+ | DP83848Q | 0x20005ca2 | MINI | NO | +--------------+--------------+--------+-----+ | DP83848V | 0x20005ca2 | | YES | +--------------+--------------+--------+-----+ | DP83848C | 0x20005ca2 | | YES | +--------------+--------------+--------+-----+ "MINI" means a less pin count variant. "IRQ"-"YES" means, the device has a interrupt line, "IRQ"-"NO" means, the device has no interrupt line. How to deal with interrupts, if the device itself has no interrupt line (and uses the same phy ID)? How to deal with the same Phy ID used for different devices and different features?
