This is a note to let you know that I've just added the patch titled

soc: sunxi: Fix missing dependency on REGMAP_MMIO

to my usb git tree which can be found at git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git in the usb-next branch.

The patch will show up in the next release of the linux-next tree (usually sometime within the next 24 hours during the week.)

The patch will also be merged in the next major kernel release during the merge window.

If you have any questions about this process, please let me know.

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.
