When enabling ARCH_SUNXI from allnoconfig, SUNXI_SRAM is enabled, but
not REGMAP_MMIO, so the kernel fails to link with an undefined reference
to __devm_regmap_init_mmio_clk. Select REGMAP_MMIO, as suggested in
drivers/base/regmap/Kconfig.
This creates the following dependency loop:
drivers/of/Kconfig:68: symbol OF_IRQ depends on IRQ_DOMAIN
kernel/irq/Kconfig:63: 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 SUNXI_SRAM
drivers/soc/sunxi/Kconfig:4: symbol SUNXI_SRAM is selected by USB_MUSB_SUNXI
drivers/usb/musb/Kconfig:63: symbol USB_MUSB_SUNXI depends on GENERIC_PHY
drivers/phy/Kconfig:7: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
drivers/phy/broadcom/Kconfig:29: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
drivers/net/phy/Kconfig:12: symbol MDIO_BUS default is visible depending on PHYLIB
drivers/net/phy/Kconfig:181: symbol PHYLIB is selected by ARC_EMAC_CORE
drivers/net/ethernet/arc/Kconfig:18: symbol ARC_EMAC_CORE is selected by ARC_EMAC
drivers/net/ethernet/arc/Kconfig:24: symbol ARC_EMAC depends on OF_IRQ
To fix the circular dependency, make USB_MUSB_SUNXI select GENERIC_PHY
instead of depending on it. This matches the use of GENERIC_PHY by all
but two other drivers.

controller based on the Mentor Graphics silicon IP. Then

configure options to match your silicon and the board

it's being used with, including the USB peripheral role,

or the USB host role, or both.
