2020-06-14treewide: replace '---help---' in Kconfig files with 'help'Masahiro Yamada
Since commit 84af7a6194e4 ("checkpatch: kconfig: prefer 'help' over '---help---'"), the number of '---help---' has been gradually decreasing, but there are still more than 2400 instances. This commit finishes the conversion. While I touched the lines, I also fixed the indentation. There are a variety of indentation styles found. a) 4 spaces + '---help---' b) 7 spaces + '---help---' c) 8 spaces + '---help---' d) 1 space + 1 tab + '---help---' e) 1 tab + '---help---' (correct indentation) f) 1 tab + 1 space + '---help---' g) 1 tab + 2 spaces + '---help---' In order to convert all of them to 1 tab + 'help', I ran the following commend: $ find . -name 'Kconfig*' | xargs sed -i 's/^[[:space:]]*---help---/\thelp/' Signed-off-by: Masahiro Yamada <masahiroy@kernel.org>

2019-06-03USB: use genalloc for USB HCs with local memoryLaurentiu Tudor
For HCs that have local memory, replace the current DMA API usage with a genalloc generic allocator to manage the mappings for these devices. To help users, introduce a new HCD API, usb_hcd_setup_local_mem() that will setup up the genalloc backing up the device local memory. It will be used in subsequent patches. This is in preparation for dropping the existing "coherent" dma mem declaration APIs. The current implementation was relying on a short circuit in the DMA API that in the end, was acting as an allocator for these type of devices.

That makes the USB role switch support option visible and selectable for the user. The class driver is also moved to drivers/usb/roles/ directory. This will fix an issue that we have with the Intel USB role switch driver on systems that don't have USB Type-C connectors: Intel USB role switch driver depends on the USB role switch class as it should, but since there was no way for the user to enable the USB role switch class, there was also no way to select that driver. USB Type-C drivers select the USB role switch class which makes the Intel USB role switch driver available and therefore hides the problem. So in practice Intel USB role switch driver was depending on USB Type-C drivers.

2018-03-22usb: roles: Add Intel xHCI USB role switch driverHans de Goede
Various Intel SoCs (Cherry Trail, Broxton and others) have an internal USB role switch for swiching the OTG USB data lines between the xHCI host controller and the dwc3 gadget controller. Note on some Cherry Trail systems there is ACPI/AML code listening to edge interrupts on the id-pin (through an _AIE ACPI method) and switching the role between ROLE_HOST and ROLE_NONE based on the id-pin. Note it does not set the role to ROLE_DEVICE, because device-mode is usually not used under Windows. The presence of AML code which modifies the cfg0 reg (on some systems) means that our read/write/modify of cfg0 may race with the AML code doing the same to avoid this we take the global ACPI lock while doing the read/write/modify.

2018-03-22usb: common: Small class for USB role switchesHeikki Krogerus
USB role switch is a device that can be used to choose the data role for USB connector. With dual-role capable USB controllers, the controller itself will be the switch, but on some platforms the USB host and device controllers are separate IPs and there is a mux between them and the connector. On those platforms the mux driver will need to register the switch. With USB Type-C connectors, the host-to-device relationship is negotiated over the Configuration Channel (CC). That means the USB Type-C drivers need to be in control of the role switch. The class provides a simple API for the USB Type-C drivers for the control. For other types of USB connectors (mainly microAB) the class provides user space control via sysfs attribute file that can be used to request role swapping from the switch.

2013-08-12usb: Move definition of USB_EHCI_BIG_ENDIAN_MMIO et al. out side of the ifs.David Daney
When CONFIG_USB_SUPPORT is not selected we get things like: scripts/kconfig/mconf Kconfig warning: (MIPS_SEAD3 && PMC_MSP && CPU_CAVIUM_OCTEON) selects USB_EHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB) It is much cleaner to make the various system Kconfigs select USB_EHCI_BIG_ENDIAN_MMIO rather than move the system config information into USB's Kconfig, but the warnings are annoying. Eliminate the warning by moving the definition of USB_EHCI_BIG_ENDIAN_MMIO outside of all the Kconfig if statements. While we are at it move USB_OHCI_BIG_ENDIAN_DESC, USB_OHCI_BIG_ENDIAN_MMIO, USB_OHCI_LITTLE_ENDIAN and USB_EHCI_BIG_ENDIAN_DESC too, as they could very well suffer similar problems for other systems. Get rid of the redundant "default n" in USB_OHCI_BIG_ENDIAN_DESC and USB_OHCI_BIG_ENDIAN_MMIO Signed-off-by: David Daney <david.daney@cavium.com> Acked-by: Alan Stern <stern@rowland.harvard.edu> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-06-06usb: host: make USB_ARCH_HAS_?HCI obsoleteArnd Bergmann
The three options USB_ARCH_HAS_{EHCI,OHCI,XHCI} are all well beyond their recommended shelf life. They have caused numerous build failures over the years because they are never completely correct, and with the move to splitting out the platform specific back-ends out of the driver, there is no real need for them any more. Also, the use of making USB_ARCH_HAS_HCD depend on it is questionable since one can always enable dummy_hc these days. This patch enables them unconditionally for all platforms and architectures, which means it is now possible to build host controller drivers for machines that are known not to come with this hardware, but that is just how we treat most other drivers. In order to minimise the impact on existing architecture code and defconfig files, all the Kconfig are left present for now. All platforms that currently do 'select USB_ARCH_HAS_*' should subsequently be changed not to select that. All drivers depending on USB_ARCH_HAS_HCD should be changed to depend on USB_SUPPORT instead.

It's an old mobile chipset that is no longer in use, and was very likely never really used with a mainline kernel.

2012-05-11usb: move ci13xxx and related code to drivers/usb/chipideaAlexander Shishkin
Since chipidea is a dual role controller, it makes sense to move it to its own directory, where we can also have host, otg and platform code related to this controller. It also makes sense to break out the driver into several compilation units like udc, host, debugging code, etc. Firstly, let's move the udc and platform code to drivers/usb/chipidea.

2012-05-01USB: Add driver for NXP ISP1301 USB transceiverRoland Stigge
This new driver registers the NXP ISP1301 chip via the I2C subsystem. The chip is the USB transceiver shared by ohci-nxp, lpc32xx_udc (gadget) and isp1301_omap. ISP1301 is a very low-level driver that primarily separates out the I2C client registration of the ISP1301 chip (including instantiation via DT), used by other drivers, and declares the chip's registers. It's only a helper driver for some OHCI and USB device drivers. The driver can be considered as a register set extension of ohci-nxp, lpc32xx-udc and isp1301_omap, which in turn know best what to do with the low level functionality (individual ISP1301 registers and timing, see the different initialization strategies in those drivers). Those drivers previously internally duplicated ISP1301 register definitions which is solved by this new isp1301 driver. The ISP1301 registers exposed via isp1301.h can be accessed by other drivers using it with standard i2c_smbus_*() accesses. Following patches let the respective USB host and gadget drivers use this driver, instead of duplicating ISP1301 handling.

commit 53c6bc24fdc8db87109a5760579cbb060fa644cf (usb: Don't make USB_ARCH_HAS_{XHCI,OHCI,EHCI} depend on USB_SUPPORT.) Removed the dependency of the USB_ARCH_HAS_* symbols on USB_SUPPORT. However the resulting Kconfig somehow caused many of the USB configuration items to appear under the top level devices menu. To fix this we reunite the 'menuconfig USB_SUPPORT' with the 'if USB_SUPPORT', and the config items magically go back to their desired location.
