| * Staging: dt3155: fix 50Hz configurationH Hartley Sweeten2010-04-301-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | According to the header file, dt3155_io.h, the 50/60 Hz configuration is controlled by a bit in the I2C CSR2 register (bit 2). The function dt3155_init_isr actually reads the I2C CONFIG register into the global I2C_CSR union variable then modifies the bit. It then does a write to the I2C CONFIG register with the global I2C_CONFIG union variable which is not even set with a value anywhere in the driver. My guess is 50Hz operation doesn't even work as-is. Fix this by actually reading and writing the correct register with the correct value.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When detaching a port from the client side (usbip --detach 0), the event thread, on the server side, is going to deadlock.

Also, CONFIG_USB_OTG selects CONFIG_USB_SUSPEND. If PM_RUNTIME is not enabled, and we try to enable USB_OTG, we will end up with CONFIG_USB_SUSPEND selected. This is due to a known bug with the select statement. This makes the build break on various OMAP configs (which have CONFIG_USB_OTG set by default, but do not yet have CONFIG_PM_RUNTIME enabled).

The xHCI specification refers to this as the Maximum Endpoint Service Interval Time Payload (Max ESIT Payload). This is used by the hardware for bandwidth management and scheduling of packets. For SuperSpeed endpoints, the maximum is calculated by multiplying the max packet size by the number of bursts and the number of opportunities to transfer within a service interval (the Mult field of the SuperSpeed Endpoint companion descriptor). Devices advertise this in the wBytesPerInterval field of their SuperSpeed Endpoint Companion Descriptor. For high speed devices, this is taken by multiplying the max packet size by the "number of additional transaction opportunities per microframe" (the high bits of the wMaxPacketSize field in the endpoint descriptor). For FS/LS devices, this is just the max packet size. The other thing we must set in the endpoint context is the Average TRB Length. This is supposed to be the average of the total bytes in the transfer descriptor (TD), divided by the number of transfer request blocks (TRBs) it takes to describe the TD. This gives the host controller an indication of whether the driver will be enqueuing a scatter gather list with many entries comprised of small buffers, or one contiguous buffer. It also takes into account the number of extra TRBs you need for every TD. This includes No-op TRBs and Link TRBs used to link ring segments together. Some drivers may choose to chain an Event Data TRB on the end of every TD, thus increasing the average number of TRBs per TD. The Linux xHCI driver does not use Event Data TRBs. In theory, if there was an API to allow drivers to state what their bandwidth requirements are, we could set this field accurately. For now, we set it to the same number as the Max ESIT payload. The Average TRB Length should also be set for bulk and control endpoints, but I have no idea how to guess what it should be.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A SuperSpeed interrupt or isochronous endpoint can define the number of "burst transactions" it can handle in a service interval. This is indicated by the "Mult" bits in the bmAttributes of the SuperSpeed Endpoint Companion Descriptor. For example, if it has a max packet size of 1024, a max burst of 11, and a mult of 3, the host may send 33 1024-byte packets in one service interval. We must tell the xHCI host controller the number of multiple service opportunities (mults) the device can handle when the endpoint is installed. We do that by setting the Mult field of the Endpoint Context before a configure endpoint command is sent down. The Mult field is invalid for control or bulk SuperSpeed endpoints.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a typo here. We should be testing "*dentry" which was just assigned instead of "dentry". This could result in dereferencing an ERR_PTR inside either usbfs_mkdir() or usbfs_create().

| * | usb: Fix tusb6010 for DMA APITony Lindgren2010-04-302-8/+27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit 18eabe2347ae7a11b3db768695913724166dfb0e introduced DMA buffer ownership. Fix tusb6010 accordingly. To compile, also dummy musb_platform_save and restore functions need to be added. Also change the order of musb_read_fifo() to happen after dma_cache_maint to have the DMA operations completed before moving the remaining unaligned bytes with PIO. The DMA access and PIO touch different areas of the FIFO, so this change only makes the code a bit easier to follow. Tested on n810 and g_ether with variable size ping test. The test seems to fail for some ping sizes, but that seems to be a different problem.
