2014-07-16usb: gadget: Gadget directory cleanup - group UDC driversAndrzej Pietrasiewicz1-611/+0
The drivers/usb/gadget directory contains many files. Files which are related can be distributed into separate directories. This patch moves the UDC drivers into a separate directory. Signed-off-by: Andrzej Pietrasiewicz <andrzej.p@samsung.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
2013-01-18usb: gadget: fsl_mxc_udc: replace MX35_IO_ADDRESS to ioremapPeter Chen1-2/+3
As mach/hardware.h is deleted, we can't visit platform code at driver. It has no phy driver to combine with this controller, so it has to use ioremap to map phy address as a workaround. Signed-off-by: Peter Chen <peter.chen@freescale.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

This patch removes redundant pointer to struct usb_endpoint_descriptor which were missed in commit 79149b8: usb: gadget: Update fsl_udc_core to use usb_endpoint_descriptor inside the struct usb_ep Due to clock framework regressions, this patch is only compile tested!

2012-05-07Merge tag 'gadget-for-v3.5' of ↵Greg Kroah-Hartman1-1/+0
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: gadget: patches for v3.5 This pull request is quite big, but mainly because there's a giant rework of the s3c_hsotg.c driver to make it friendlier for other users. Samsung Exynos platforms use the DesignWare Core USB2 IP from Synopsys so it's a bit unfair to have the driver work for Samsung platforms only. In short, the big rework is in preparation to make the driver more reusable. Another big rework in this pull request came from Ido, where he's removing the redundant pointer for the endpoint descriptor from the controller driver's own endpoint representation. The same pointer is available through the generic struct usb_ep structure. Also on this pull request is the conversion of a few extra controller drivers to the new style registration, which allows multiple controllers to be available on the same platform and helps remove global pointers from those drivers. Together with those big changes, there's the usual fixes and cleanups to gadget drivers. Nothing major.

2011-05-02USB: fsl_udc_core: support device mode of MPC5121E DR USB ControllerAnatolij Gustschin1-0/+2
Extend the FSL UDC driver to support MPC5121E DR USB Controller operation in device mode. Add MPC5121E specific init/uninit at probe and remove and isolate system interface register accesses when running on MPC5121E SoC, as these registers are not available on this platform. This patch relies on previous patch for supporting big endian registers and descriptors access in the FSL UDC driver. Additionally support endpoint FIFO status operation by providing appropriate callback in endpoint ops structure. Also flush cache for the req buffer used for GetStatus reply. Without this, the correct reply to an endpoint GetStatus is written to 'req', but doesn't make it out to the USB bus since the buffer hasn't been flushed. This would cause the USBCV Halt Endpoint test to fail (according to changelog in Freescale LTIB driver code).

2011-05-02USB: fsl_udc_core: prepare for SoCs with BE registers and descriptorsAnatolij Gustschin1-0/+2
On some SoCs, the USB controller registers and descriptors can be big or little endian, depending on the version of the chip. In order to be able to run the same kernel binary on different versions of an SoC, the BE/LE decision must be made at run time. Provide appropriate register and descriptor accessors which are configurable at run time using the configuration flags from fsl_usb2_platform_data data structure. This is in preparation for adding support for MPC5121E DR USB2 Controller to the FSL UDC driver.

2009-06-15USB: gadget: Add i.MX3x support to the fsl_usb2_udc driverGuennadi Liakhovetski1-0/+18
This patch adds support for i.MX3x (only tested with i.MX31 so far) ARM SoCs to the fsl_usb2_udc driver. It also moves PHY configuration before controller reset, because otherwise an ULPI PHY doesn't get a reset and doesn't function after a reboot. The problem with longer control transfers is still not fixed. The patch renames the fsl_usb2_udc.c file to fsl_udc_core.c to preserve the same module name for user-space backwards compatibility.

2008-07-25Rename WARN() to WARNING() to clear the namespaceArjan van de Ven1-1/+1
We want to use WARN() as a variant of WARN_ON(), however a few drivers are using WARN() internally. This patch renames these to WARNING() to avoid the namespace clash.

2007-04-27USB: add Freescale high-speed USB SOC device controller driverLi Yang1-0/+579
Freescale high-speed USB SOC can be found on some Freescale processors among different architectures. It supports both host and device functions. This driver adds its device support for Linux USB Gadget layer. It is tested on MPC8349 and MPC8313, but should work on other platforms with minor tweaks. The driver passed USBCV 1.3 compliance tests. Note that this driver doesn't yet include OTG support.
