net: mscc: ocelot: rethink Kconfig dependencies again
Having the users of MSCC_OCELOT_SWITCH_LIB depend on REGMAP_MMIO was a
bad idea, since that symbol is not user-selectable. So we should have
kept a 'select REGMAP_MMIO'.
When we do that, we run into 2 more problems:
- By depending on GENERIC_PHY, we are causing a recursive dependency.
But it looks like GENERIC_PHY has no other dependencies, and other
drivers select it, so we can select it too:
drivers/of/Kconfig:69:error: recursive dependency detected!
drivers/of/Kconfig:69: symbol OF_IRQ depends on IRQ_DOMAIN
kernel/irq/Kconfig:68: symbol IRQ_DOMAIN is selected by REGMAP
drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_MMIO
drivers/base/regmap/Kconfig:39: symbol REGMAP_MMIO is selected by MSCC_OCELOT_SWITCH_LIB
drivers/net/ethernet/mscc/Kconfig:15: symbol MSCC_OCELOT_SWITCH_LIB is selected by MSCC_OCELOT_SWITCH
drivers/net/ethernet/mscc/Kconfig:22: symbol MSCC_OCELOT_SWITCH depends on GENERIC_PHY
drivers/phy/Kconfig:8: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
drivers/phy/broadcom/Kconfig:41: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
drivers/net/phy/Kconfig:13: symbol MDIO_BUS depends on MDIO_DEVICE
drivers/net/phy/Kconfig:6: symbol MDIO_DEVICE is selected by PHYLIB
drivers/net/phy/Kconfig:254: symbol PHYLIB is selected by ARC_EMAC_CORE
drivers/net/ethernet/arc/Kconfig:19: symbol ARC_EMAC_CORE is selected by ARC_EMAC
drivers/net/ethernet/arc/Kconfig:25: symbol ARC_EMAC depends on OF_IRQ
- By depending on PHYLIB, we are causing a recursive dependency. PHYLIB
only has a single dependency, "depends on NETDEVICES", which we are
already depending on, so we can again hack our way into conformance by
turning the PHYLIB dependency into a select.
