usb: phy: fix link errors

2019-03-13T21:04:12+00:00

[ Upstream commit f2105d42597f4d10e431b195d69e96dccaf9b012 ] Fix link errors when CONFIG_FSL_USB2_OTG is enabled and USB_OTG_FSM is set to module then the following link error occurs. aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `fsl_otg_ioctl': drivers/usb/phy/phy-fsl-usb.c:1083: undefined reference to `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.c:1083:(.text+0x574): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `fsl_otg_start_srp': drivers/usb/phy/phy-fsl-usb.c:674: undefined reference to `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.c:674:(.text+0x61c): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `fsl_otg_set_host': drivers/usb/phy/phy-fsl-usb.c:593: undefined reference to `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.c:593:(.text+0x7a4): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `fsl_otg_start_hnp': drivers/usb/phy/phy-fsl-usb.c:695: undefined reference to `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.c:695:(.text+0x858): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `a_wait_enum': drivers/usb/phy/phy-fsl-usb.c:274: undefined reference to `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.c:274:(.text+0x16f0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `otg_statemachine' aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o:drivers/usb/phy/phy-fsl-usb.c:619: more undefined references to `otg_statemachine' follow aarch64-linux-gnu-ld: drivers/usb/phy/phy-fsl-usb.o: in function `fsl_otg_set_peripheral': drivers/usb/phy/phy-fsl-usb.c:619:(.text+0x1fa0): relocation truncated to fit: R_AARCH64_CALL26 against undefined symbol `otg_statemachine' make[1]: *** [Makefile:1020: vmlinux] Error 1 make[1]: Target 'Image' not remade because of errors. make: *** [Makefile:152: sub-make] Error 2 make: Target 'Image' not remade because of errors. Rework so that FSL_USB2_OTG depends on that the USB_OTG_FSM is builtin. Signed-off-by: Anders Roxell Signed-off-by: Felipe Balbi Signed-off-by: Sasha Levin

phy: tegra: select USB_COMMON

2018-05-31T10:50:40+00:00

A built-in PHY driver cannot link against modular USB core code: drivers/usb/phy/phy-tegra-usb.o: In function `tegra_usb_phy_probe': phy-tegra-usb.c:(.text+0x6bc): undefined reference to `usb_get_dr_mode' This uses a 'select' statement in Kconfig like we have for other such PHY drivers.

usb: phy: Add Kconfig entry for Tegra PHY driver

2018-04-23T07:50:57+00:00

Tegra's EHCI driver has a build dependency on Tegra's PHY driver and currently Tegra's PHY driver is built only when Tegra's EHCI driver is built. Add own Kconfig entry for the Tegra's PHY driver so that drivers other than ehci-tegra (like ChipIdea UDC) could work with ehci-tegra driver being disabled in kernels config by allowing user to manually select the PHY driver.

usb: phy: remove phy-qcom-8x16-usb.c

2017-11-01T16:08:10+00:00

No Qualcomm SoC requires the "phy-qcom-8x16-usb.c" USB phy driver support any more, so remove the code. Suggested-by: Stephen Boyd Signed-off-by: Alex Elder Acked-by: Bjorn Andersson Acked-by: Andy Gross Signed-off-by: Greg Kroah-Hartman

usb: phy: Introduce one extcon device into usb phy

2017-05-17T11:15:28+00:00

Usually usb phy need register one extcon device to get the connection notifications. It will remove some duplicate code if the extcon device is registered using common code instead of each phy driver having its own related extcon APIs. So we add one pointer of extcon device into usb phy structure, and some other helper functions to register extcon. Signed-off-by: Baolin Wang Signed-off-by: Felipe Balbi

usb: phy: Remove unused config

2017-03-23T12:48:44+00:00

Since the old common Samsung USB PHY code has been removed by commit ea2fdf8423 ("usb: phy: samsung: remove old common USB PHY code"), thus remove the unused config. Signed-off-by: Baolin Wang Signed-off-by: Greg Kroah-Hartman

usb: gadget: move gadget API functions to udc-core

2016-06-21T07:38:34+00:00

instead of defining all functions as static inlines, let's move them to udc-core and export them with EXPORT_SYMBOL_GPL, that way we can make sure that only GPL drivers will use them. As a side effect, it'll be nicer to add tracepoints to the gadget API. While at that, also fix Kconfig dependencies to avoid randconfig build failures.

usb: phy: phy-am335x: bypass first VBUS sensing for host-only mode

2015-12-16T16:07:25+00:00

To prevent VBUS contention, the am335x MUSB phy senses VBUS first before transitioning to host mode. However, for host-only mode, VBUS could be directly tied to 5V power rail which could prevent MUSB transitions to host mode. This change receives dr_mode of the controller then bypass the first VBUS sensing for host-only mode, so that MUSB can work in host mode event if VBUS is tied to 5V.
