2010-02-17tegra usb:Fix suspend/resume failure in OTG mode.Venkat Moganty
In OTG mode during suspend/resume functionalities both device driver and host driver are accessing the USB1 controller registers with out checking the operation mode. Host driver is reading wrong status values from the registers causing the stack dump. This is fixed by checking the OTG state and guarding the hardware to access by only one driver(host or device), which is currently in operation. Bug 651253 : [Whistler] : USB gadget and/or EHCI bus suspend/resume API causes crash 1st after suspend/resume Tested on : Android/whistler with suspend/resume framework enabled. Suspend/resume sequence work fine with OTG enabled.

2010-02-12f_mass_storage: allow platform to set bulk buffer sizeGary King
add a field to the android_usb_platform_data structure to allow platforms to specify the size of the bulk transfer buffer; if unspecified, default to the BULK_BUFFER_SIZE defined by f_mass_storage.c (previously defined as 4KiB). on harmony (tegra 2), performance of a class 10 SD card mounted as USB mass storage through this gadget has been measured to increase from ~7MB/sec read to ~17MB/sec read by increasing the buffer size from 4KiB to 16KiB.

2010-02-11tegra usbh: whistler suspend/resume failure fixBitan Biswas
With OTG disabled on whistler the suspend/resume code was hanging. The reason is because register reads hang when clocks are disabled. This fix tries to skip the suspend calls when device is already in suspend state. This avoids attempts to read register with clocks disabled. Bug 651253 : [Whistler] : USB gadget and/or EHCI bus suspend/resume API causes crash 1st after suspend/resume Reviewed by: vmoganty Tested on : whistler with suspend/resume framework enabled. Suspend/resume sequence seems to work fine on whistler and harmony with OTG disabled in kernel and odm_query. Change-Id: Iedc096648deab5c3b80350446c4ee67f625df27e

2010-01-25fsl_udc_core: Fix USB chapter9 compliance tests.Venkat Moganty
In udc driver ch9getstatus() function is not mapping the status buffer's virtual address to hardware for transfering the status data over dma. On USB bus get status information is not going properly to the host. Hence, few chapter9 tests are failing. Fixed this by maping the status buffer address to the dmable address. With this fix USB chapter9 (usb command verifier) tests are passing. Bug 633510: Chapter 9 USB Compliance tests are failed. Tested on whistler/android/usb1 port in device mode.

2009-12-21ehci: enable clocks on tegra during shutdownGary King

2009-12-09fsl_udc_core: add support for Tegra UDC controllerGary King
The USB device controller in Tegra SoCs shares a lot in common with the Freescale USB device controller, so it makes sense to share the implementation Aside from some functional quirks in the Tegra controller, the most noteworthy difference is that queue heads are stored in an internal RAM on Tegra, rather than in DMA-allocated memory on Freescale.

2009-12-08USB: gadget: Add i.MX3x support to the fsl_usb2_udc driverGuennadi Liakhovetski
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.

The "c-enter" USB to Toshiba 1.8" IDE enclosure needs special treatment to work flawlessly. This patch is absolutely trivial, as the integrated USB-IDE bridge is already identified to be an "unusual" device, only the bcdDevice is different (lower) to the bcdDeviceMin already included in the kernel.

2009-03-17USB: EHCI: expedite unlinks when the root hub is suspendedAlan Stern
This patch (as1225) fixes a bug in ehci-hcd. The condition for whether unlinked QHs can become IDLE should not be that the controller is halted, but rather that the controller isn't running. In other words when the root hub is suspended, the hardware doesn't own any QHs. This fixes a problem that can show up during hibernation: If a QH is only partially unlinked when the root hub is frozen, then when the root hub is thawed the QH won't be in the IDLE state. As a result it can't be used properly for new URB submissions.

2009-03-17USB: EHCI: Fix isochronous URB leakKarsten Wiese
ehci-hcd uses usb_get_urb() and usb_put_urb() in an unbalanced way causing isochronous URB's kref.counts incrementing once per usb_submit_urb() call. The culprit is *usb being set to NULL when usb_put_urb() is called after URB is given back. Due to other fixes there is no need for ehci-hcd to deal with usb_get_urb() nor usb_put_urb() anymore, so patch removes their usages in ehci-hcd. Patch also makes ehci_to_hcd(ehci)->self.bandwidth_allocated adjust, if a stream finishes.
