E.g. for RTL838x this is 0xfff. - * - * On the other hand Realtek PHYs usually make use of select register 0x1f to switch - * pages. There is no problem to issue separate page and access bus calls to the PHYs - * when they are not attached to an Realtek SoC. The paradigm should be to keep the PHY - * implementation bus independent. - * - * As if this is not enough the PHY packages consist of 4 or 8 ports that all can be - * programmed individually. Some registers are only available on port 0 and configure - * the whole package. - * - * To bring all this together we need a tricky bus design that intercepts select page - * calls but lets raw page accesses through. And especially knows how to handle raw - * accesses to the select register. Additionally we need the possibility to write to - * all 8 ports of the PHY individually. - * - * While the C45 clause stuff is pretty standard the legacy functions basically track - * the accesses and the state of the bus with the attributes page[], raw[] and portaddr - * of the bus_priv structure. The page selection works as follows: - * - * phy_write(phydev, RTMDIO_PAGE_SELECT, 12) : store internal page 12 in driver - * phy_write(phydev, 7, 33) : write page=12, reg=7, val=33 - * - * or simply - * - * phy_write_paged(phydev, 12, 7, 33) : write page=12, reg=7, val=33 - * - * The port selection works as follows and must be called under a held mdio bus lock - * - * __mdiobus_write(bus, RTMDIO_PORT_SELECT, 4) : switch to port 4 - * __phy_write(phydev, RTMDIO_PAGE_SELECT, 11) : store internal page 11 in driver - * __phy_write(phydev, 8, 19) : write page=11, reg=8, val=19, port=4 - * - * Any Realtek PHY that will be connected to this bus must simply provide the standard - * page functions: - * - * define RTL821X_PAGE_SELECT 0x1f - * - * static int rtl821x_read_page(struct phy_device *phydev) - * { - * return __phy_read(phydev, RTL821X_PAGE_SELECT); - * } - * - * static int rtl821x_write_page(struct phy_device *phydev, int page) - * { - * return __phy_write(phydev, RTL821X_PAGE_SELECT, page); - * } - * - * In case there are non Realtek PHYs attached to the bus the logic might need to be - * reimplemented. For now it should be sufficient. - */ - -struct rtmdio_bus_priv { - u16 id; - u16 family_id; - int extaddr; - int rawpage; - int page[RTMDIO_MAX_PORT]; - bool raw[RTMDIO_MAX_PORT]; - int smi_bus[RTMDIO_MAX_PORT]; - u8 smi_addr[RTMDIO_MAX_PORT]; - u32 sds_id[RTMDIO_MAX_PORT]; - bool smi_bus_isc45[RTMDIO_MAX_SMI_BUS]; - bool phy_is_internal[RTMDIO_MAX_PORT]; - phy_interface_t interfaces[RTMDIO_MAX_PORT]; - int (*read_mmd_phy)(u32 port, u32 addr, u32 reg, u32 *val); - int (*write_mmd_phy)(u32 port, u32 addr, u32 reg, u32 val); - int (*read_phy)(u32 port, u32 page, u32 reg, u32 *val); - int (*write_phy)(u32 port, u32 page, u32 reg, u32 val); -}; - -/* - * Provide a generic read/write function so we can access arbitrary ports on the bus. - * E.g. other ports of a PHY package on the bus.
