With this applied, I get the following build error:
drivers/of/Kconfig:69:error: recursive dependency detected!
drivers/of/Kconfig:69: symbol OF_IRQ depends on IRQ_DOMAIN
kernel/irq/Kconfig:59: symbol IRQ_DOMAIN is selected by REGMAP
drivers/base/regmap/Kconfig:7: symbol REGMAP default is visible depending on REGMAP_I2C
drivers/base/regmap/Kconfig:20:symbol REGMAP_I2C is selected by TYPEC_STUSB160X
drivers/usb/typec/Kconfig:66: symbol TYPEC_STUSB160X depends on USB_ROLE_SWITCH
drivers/usb/roles/Kconfig:3: symbol USB_ROLE_SWITCH is selected by USB_MUSB_MEDIATEK
drivers/usb/musb/Kconfig:119: symbol USB_MUSB_MEDIATEK depends on GENERIC_PHY
drivers/phy/Kconfig:8: symbol GENERIC_PHY is selected by PHY_BCM_NS_USB3
drivers/phy/broadcom/Kconfig:49: symbol PHY_BCM_NS_USB3 depends on MDIO_BUS
drivers/net/mdio/Kconfig:13: symbol MDIO_BUS depends on MDIO_DEVICE
drivers/net/mdio/Kconfig:6: symbol MDIO_DEVICE is selected by PHYLIB

drivers/net/ethernet/arc/Kconfig:25: symbol ARC_EMAC depends on OF_IRQ
For a resolution refer to Documentation/kbuild/kconfig-language.rst
subsection "Kconfig recursive dependency limitations"
So I can't take it as-is :(
thanks,
