phy: tegra: xusb: Make USB_CONN_GPIO select conditional on GPIOLIBkconfiglint reports: K006: config PHY_TEGRA_XUSB selects USB_CONN_GPIO which depends on GPIOLIB, but PHY_TEGRA_XUSB does not depend on GPIOLIB K002: config PHY_TEGRA_XUSB selects visible symbol USB_CONN_GPIO which has dependenciesUSB_CONN_GPIO was introduced in commit 4602f3bff266 ("usb: common: add USBGPIO based connection detection driver") with a hard dependency on GPIOLIB,since it needs GPIO pins to detect USB cable connection state.Commit f67213cee2b3 ("phy: tegra: xusb: Add usb-role-switch support") added`select USB_CONN_GPIO` to PHY_TEGRA_XUSB to support USB role switching viaGPIO-based detection. At that time, PHY_TEGRA_XUSB depended only on`ARCH_TEGRA`, and both the ARM32 and ARM64 ARCH_TEGRA Kconfig definitionsselect GPIOLIB, so the missing explicit GPIOLIB guard was not a functionalproblem — GPIOLIB is always available when ARCH_TEGRA is enabled.Later, commit 0d5c9bc7c680 ("phy: tegra: Select USB_COMMON forusb_get_maximum_speed()") added `depends on USB_SUPPORT` but still did notaddress the GPIOLIB gap.The select can force USB_CONN_GPIO on without its GPIOLIB dependency beingsatisfied if the Kconfig dependencies were ever restructured. Make theselect conditional with `select USB_CONN_GPIO if GPIOLIB` to make thedependency explicit. This mirrors how other drivers handle optionalGPIO-dependent selects throughout the kernel.Assisted-by: Claude:claude-opus-4-6 kconfiglintSigned-off-by: Sasha Levin Link: https://patch.msgid.link/20260426000309.54959-1-sashal@kernel.orgSigned-off-by: Vinod Koul List of files: /linux/drivers/phy/tegra/Kconfig

phy: tegra: Select USB_COMMON for usb_get_maximum_speed()The usb_get_maximum_speed() function is part of the usb-common module,so enable it by selecting the corresponding Kconfig symbol.While at it, also make sure to depend on USB_SUPPORT because USB_PHYrequires that. This can lead to Kconfig conflicts if USB_SUPPORT is notenabled while attempting to enable PHY_TEGRA_XUSB.Reported-by: kbuild test robot Suggested-by: Nathan Chancellor Signed-off-by: Thierry Reding Link: https://lore.kernel.org/r/20200330101038.2422389-1-thierry.reding@gmail.comSigned-off-by: Greg Kroah-Hartman List of files: /linux/drivers/phy/tegra/Kconfig

phy: Add Tegra XUSB pad controller supportAdd a new driver for the XUSB pad controller found on NVIDIA Tegra SoCs.This hardware block used to be exposed as a pin controller, but it turnsout that this isn't a good fit.
