KSZ8563 has two 100Mbit PHYs and CPU port with RGMII support. Since 1000Mbit configuration for the RGMII capable MAC is present, we should use per port validation. As main part of migration to per-port validation we need to rework ksz9477_switch_init() function. Which is using undocumented REG_GLOBAL_OPTIONS register to detect per-chip Gbit support. So, it is related to some sort of risk for regressions. To reduce this risk I compared the code with publicly available documentations. This function will executed on following currently supported chips: struct ksz_chip_data OF compatible KSZ9477 KSZ9477 KSZ9897 KSZ9897 KSZ9893 KSZ9893, KSZ9563 KSZ8563 KSZ8563 KSZ9567 KSZ9567 Only KSZ9893, KSZ9563, KSZ8563 document existence of 0xf == REG_GLOBAL_OPTIONS register with bit field description "SKU ID": KSZ9893 0x0C KSZ9563 0x1C KSZ8563 0x3C The existence of hidden flags is not documented. KSZ9477, KSZ9897, KSZ9567 do not document this register at all. Only KSZ8563 is documented as non Gbit chip: 100Mbit PHYs and RGMII CPU port. So, this change should not introduce a regression for configurations with properly used OF compatibles.
