I got below build error: ERROR: "tegra_xusb_padctl_legacy_probe" [drivers/phy/tegra/phy-tegra-xusb.ko] undefined! with below build configuration: CONFIG_ARCH_TEGRA=y CONFIG_PINCTRL_TEGRA_XUSB=y CONFIG_PHY_TEGRA_XUSB=y The problem is below line in drivers/pinctrl/Makefile obj-$(CONFIG_PINCTRL_TEGRA) += tegra/ So even CONFIG_PINCTRL_TEGRA_XUSB=y is set, kbuild still does not compile the code in drivers/pinctrl/tegra folder if !CONFIG_PINCTRL_TEGRA. phy-tegra-xusb.c does not use any symbol from pinctrl-tegra.c, so build pinctrl-tegra.c only when CONFIG_PINCTRL_TEGRA is set.
