This kind of looks like a C45 only MDIO bus.
#define MMD_DEVICE_ID_VENDOR_MII 0x1F
#define SR_MII MMD_DEVICE_ID_VENDOR_MII
This is identical to MDIO_MMD_VEND2.
#define SR_MII_RESET BIT(15)
#define SR_MII_LOOPBACK BIT(14)
#define SR_MII_SPEED_100MBIT BIT(13)
#define SR_MII_AUTO_NEG_ENABLE BIT(12)
#define SR_MII_POWER_DOWN BIT(11)
#define SR_MII_AUTO_NEG_RESTART BIT(9)
#define SR_MII_FULL_DUPLEX BIT(8)
#define SR_MII_SPEED_1000MBIT BIT(6)
A standard BMCR.
#define MMD_SR_MII_STATUS 0x0001
#define MMD_SR_MII_ID_1 0x0002
#define MMD_SR_MII_ID_2 0x0003
#define MMD_SR_MII_AUTO_NEGOTIATION 0x0004
Same as:
#define MII_BMSR 0x01 /* Basic mode status register */
#define MII_PHYSID1 0x02 /* PHYS ID 1 */
#define MII_PHYSID2 0x03 /* PHYS ID 2 */
#define MII_ADVERTISE 0x04 /* Advertisement control reg */
So i think your first patch should be to replace all these with the
standard macros.
That will then help make it clearer how much is generic, could the
existing helpers be used, probably with a wrapper to make your C22
device mapped to C45 MDIO_MMD_VEND2 look like a C22 device?
