| * USB: fsl_udc_core: fix build breakage when building for ARM archAnatolij Gustschin2011-07-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 09ba0def (USB: fsl_udc_core: prepare for SoCs with BE registers and descriptors) introduced build breakage on ARM arch. Fix it by setting accessors using a static inline function which is a nop when compiling the driver for ARM arch. Commit 2ea6698 (USB: fsl_udc_core: support device mode of MPC5121E DR USB Controller) caused another breakage on ARM by using flush_dcache_range(). Don't use it, convert to the DMA API usage instead. USB2.0CV Halt Endpoint Test succeeds on PPC. Tested both on ARM i.MX31 and mpc5121 PPC, also with CONFIG_DMA_API_DEBUG enabled.

* USB: CONFIG_USB_GADGET_DUALSPEED is not user-configurableAlan Stern2011-06-07
| | | | | | | | | | | | | This patch (as1468) changes the Kconfig definition for USB_GADGET_DUALSPEED. This option is determined entirely by which device controller drivers are to be built, through Select statements; it does not need to be (and should not be) configurable by the user. Also, the "default n" line is superfluous -- everything defaults to N.

* USB: dummy-hcd needs the has_tt flagAlan Stern2011-06-07
| | | | | | | | | | | Like with other host controllers capable of operating at both high speed and full speed, we need to indicate that the emulated controller presented by dummy-hcd has this ability. Otherwise usbcore will not accept full-speed gadgets under dummy-hcd. This patch (as1469) sets the appropriate has_tt flag.

| * usb: gadget: composite: Allow function drivers to pause control transfersRoger Quadros2011-05-10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some USB function drivers (e.g. f_mass_storage.c) need to delay or defer the data/status stages of standard control requests like SET_CONFIGURATION or SET_INTERFACE till they are done with their bookkeeping and are actually ready for accepting new commands to their interface. They can now achieve this functionality by returning USB_GADGET_DELAYED_STATUS in their setup handlers (e.g. set_alt()). The composite framework will then defer completion of the control transfer by not completing the data/status stages. This ensures that the host does not send new packets to the interface till the function driver is ready to take them. When the function driver that requested for USB_GADGET_DELAYED_STATUS is done with its bookkeeping, it should signal the composite framework to continue with the data/status stages of the control transfer. It can do so by invoking the new API usb_composite_setup_continue(). This is where the control transfer's data/status stages are completed and host can initiate new transfers. The DELAYED_STATUS mechanism is currently only supported if the expected data phase is 0 bytes (i.e. w_length == 0). Since SET_CONFIGURATION and SET_INTERFACE are the only cases that will use this mechanism, this is not a limitation.

| * USB: OTG: msm: Implement charger detectionPavankumar Kondeti2011-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement good battery algorithm defined in the battery charging V1.2 spec for detecting different charging ports. USB hardware is put into low power mode when connected to a dedicated charging port. vbus_draw and set_power methods are implemented for determining the allowed current from Host in different states (un-configured/suspend/configured). The charger block is implemented using vendor specific registers and the PHY used in MSM8960(28nm PHY) different from older targets like MSM8x60 and MSM7x30(45nm PHY). The PHY vendor and product id registers are not implemented in the above chipsets. Hence PHY type is passed via platform data.

| * fsl/usb: Unused endpoint failure for USB gadgetRamneek Mehresh2011-05-06
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Though USB controller works without this most of the time, an issue was faced where USB was configured as printer device and it was dropping first packet(64 bytes) in full speed mode due to DATA PID mismatch. The problem gets resolved once unused endpoints are configured as bulk. As per P1020 RM (Table17-31, bits 19-18, bits 3-2) "When only one endpoint (RX or TX, but not both) of an endpoint pair is used, the unused endpoint should be configured as a bulk type endpoint."

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Current code returns 0 even if it can't handle the request. This leads to timeouts when an unhandled request is sent: Bus 001 Device 003: ID 0525:c0de Netchip Technology, Inc. Device Descriptor: [..] can't get device qualifier: Connection timed out [..] change the code to return EOPNOTSUPP in such cases.

To quote Alan Stern: The necessity for this patch has been under discussion. It turns out the UDC that Mian has been working on and Felipe's UDC have contradictory requirements. Mian's UDC driver wants a bulk-OUT transfer length to be shorter than the maxpacket size if a short packet is expected, whereas Felipe's UDC hardware always needs bulk-OUT transfer lengths to be evenly divisible by the maxpacket size. Mian has agreed to go back over the driver to resolve this conflict. This means we probably will not want this patch after all. (In fact, we may ultimately decide to change the gadget framework to require that bulk-OUT transfer lengths _always_ be divisible by the maxpacket size -- only the g_file_storage and g_mass_storage gadgets would need to be changed.)
