* usb: Move USB_UHCI_BIG_ENDIAN_* out of USB_SUPPORTJames Hogan2018-02-151-8/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | Move the Kconfig symbols USB_UHCI_BIG_ENDIAN_MMIO and USB_UHCI_BIG_ENDIAN_DESC out of drivers/usb/host/Kconfig, which is conditional upon USB && USB_SUPPORT, so that it can be freely selected by platform Kconfig symbols in architecture code. For example once the MIPS_GENERIC platform selects are fixed in commit 2e6522c56552 ("MIPS: Fix typo BIG_ENDIAN to CPU_BIG_ENDIAN"), the MIPS 32r6_defconfig warns like so: warning: (MIPS_GENERIC) selects USB_UHCI_BIG_ENDIAN_MMIO which has unmet direct dependencies (USB_SUPPORT && USB) warning: (MIPS_GENERIC) selects USB_UHCI_BIG_ENDIAN_DESC which has unmet direct dependencies (USB_SUPPORT && USB) Fixes: 2e6522c56552 ("MIPS: Fix typo BIG_ENDIAN to CPU_BIG_ENDIAN") Signed-off-by: James Hogan <jhogan@kernel.org> Cc: Corentin Labbe <clabbe.montjoie@gmail.com> Cc: Ralf Baechle <ralf@linux-mips.org> Cc: Paul Burton <paul.burton@mips.com> Cc: linux-usb@vger.kernel.org Cc: linux-mips@linux-mips.org Acked-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Patchwork: https://patchwork.linux-mips.org/patch/18559/
* usb: xhci: Add DbC support in xHCI driverLu Baolu2017-12-081-0/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | xHCI compatible USB host controllers(i.e. super-speed USB3 controllers) can be implemented with the Debug Capability(DbC). It presents a debug device which is fully compliant with the USB framework and provides the equivalent of a very high performance full-duplex serial link. The debug capability operation model and registers interface are defined in 7.6.8 of the xHCI specification, revision 1.1. The DbC debug device shares a root port with the xHCI host. By default, the debug capability is disabled and the root port is assigned to xHCI. When the DbC is enabled, the root port will be assigned to the DbC debug device, and the xHCI sees nothing on this port. This implementation uses a sysfs node named <dbc> under the xHCI device to manage the enabling and disabling of the debug capability. When the debug capability is enabled, it will present a debug device through the debug port. This debug device is fully compliant with the USB3 framework, and it can be enumerated by a debug host on the other end of the USB link. As soon as the debug device is configured, a TTY serial device named /dev/ttyDBC0 will be created.

* usb: host: ohci-omap3: Remove driver in favor of ohci-platformTony Lindgren2017-06-031-1/+5
| | | | | | | | | | | | | | | | | | | This driver is no longer needed and can be removed. The reason why it's safe to remove this driver is that most omap devices don't have a USB low-speed or full-speed compatible PHY installed and configured with drivers/mfd/omap-usb-host.c. This means that devices like beagleboard and pandaboard need to use a high-speed USB hub in order to use devices like keyboard and mice. Currently the only known configured for a full-speed PHY is the mdm6600 modem on droid 4 and I've verified it works just fine with ohci-platform.

* usb/uhci: Add support for Aspeed BMC SoCsBenjamin Herrenschmidt2017-05-251-1/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Aspeed 2400/2500 families have a variant of UHCI which requires some quirks to the driver to work: - The register offsets are different. We add a remapping helper. - All accesses have to be done via 32-bit loads and stores. We force all accessors to use readl/writel. This is of no consequence for reads as we never read "in the middle" of a register. For writes it also works fine as the registers only actually implement the bits we try to write (16-bit for the registers accessed with writew and 8-bit for the register accessed with writeb), so always using a 32-bit write will have no negative effect. We never do partial writes. - The resume detect interrupt is broken - The number of ports is (optionally) provided via the device-tree Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org> Acked-by: Alan Stern <stern@rowland.harvard.edu> -- v2.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The firmware of R-Car USB 3.0 host controller will control the reset. So, if the xhci driver doesn't do firmware downloading (e.g. kernel configuration is CONFIG_USB_XHCI_PLATFORM=y and CONFIG_USB_XHCI_RCAR is not set), the reset of USB 3.0 host controller doesn't work correctly. Then, the host controller will cause long wait in xhci_reset() because the CMD_RESET bit of op_regs->command is not cleared for 10 seconds. So, this patch modifies the Kconfig to enable both CONFIG_USB_XHCI_PLATFORM and CONFIG_USB_XHCI_RCAR.

This controller, when loaded with external firmware, exposes an interface compliant with xHCI. This driver loads the firmware, starts the controller, and is able to service host-specific messages sent by the controller's firmware. The controller also supports USB device mode as well as powergating of the SuperSpeed and host-controller logic when not in use, but support for these is not yet implemented.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The USB_FSL_MPH_DR_OF symbol is used to ensure the code that interprets the DR device node is built whenever one of the two drivers (EHCI or UDC) for the platform is enabled. However, if CONFIG_USB is disabled and we only support gadget mode, this causes a Kconfig warning: warning: (USB_FSL_USB2) selects USB_FSL_MPH_DR_OF which has unmet direct dependencies (USB_SUPPORT && USB) We can avoid this warning by simply no longer using the symbol, and making sure we enter the drivers/usb/host/ directory when the UDC driver is enabled that needs the file, and then we use Makefile syntax to ensure the file is built-in if needed. There is currently a dependency on CONFIG_OF, but this is redundant, as we already know that this is set unconditionally for the platforms that use this driver.

However, it is currently still necessary to enable it in order to select USB_OHCI_BIG_ENDIAN_MMIO. Make CPU_CAVIUM_OCTEON select that as well, so that USB_OCTEON_OHCI is really obsolete. The old ohci-octeon and ehci-octeon drivers also only enabled big-endian MMIO in case the CPU was big-endian. Make the selections of USB_EHCI_BIG_ENDIAN_MMIO and USB_OHCI_BIG_ENDIAN_MMIO conditional, to match this.
