| | * | | | | | USB: serial: remove zte_ev driverJohan Hovold2014-09-15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The zte_ev driver is based on code (once) distributed by ZTE that still appears to originally have been reverse-engineered and bolted onto the generic driver. A closer analysis of the zte_ev setup code reveals that it consists of standard CDC requests (SET/GET_LINE_CODING and SET_CONTROL_LINE_STATE) but unfortunately fails to get some of those right. In particular, as reported by Lei Liu, it fails to lower DTR/RTS on close. It also appears that the control requests lack the interface argument. Since line control is already handled properly by the option driver, and the SET/GET_LINE_CODING requests appears to be redundant (amounts to a SET 9600 8N1) let's remove the redundant zte_ev driver. Also move the remaining ZTE PIDs to the generic option modem driver. Reported-by: Lei Liu <liu.lei78@zte.com.cn> Signed-off-by: Johan Hovold <johan@kernel.org>

| * | | | | | usb: dwc2: handle DMA buffer unmapping sanelyPaul Zimmerman2014-09-19

For IN transfers, it left the URB DMA buffer mapped until the transfer completed, then synced it, copied the data from the bounce buffer, then synced it again. Instead of that, just call usb_hcd_unmap_urb_for_dma() to unmap the buffer before starting the transfer. Then no syncing is required when doing the copy. This should also allow handling of other types of mappings besides just dma_map_single() ones. Also reduce the size of the bounce buffer allocation for Isoc endpoints to 3K, since that's the largest possible transfer size. Tested on Raspberry Pi and Altera SOCFPGA.

Up to now there were initialized 16 TX FIFOs, but we use only 8 IN endpoints, so we can split available memory for 8 FIFOs to have more memory for each one. It needed to do some small modifications in few places in code, because there was assumption that TX FIFO numbers assigned to endpoints are the same as the endpoint numbers, which is not true since we have dynamic FIFO assigning.

Audio and UVC gadgets can now be used with our configfs-based binding. We have three PHY drivers being removed because a new one has been added using new PHY framework. Gadget framework got a new ->reset callback preparing for some other changes to come on next merge window. A few new drivers came in as well; among those we have a new UDC driver from Xilinx and two new glue layers for DWC3 (ST and Qualcomm). DWC3 also learned about tracepoints which will help debugging quite a bit. Other than that, a big series of non-critical fixes and cleanups. All patches have been on linux-next for quite a bit of time and I boot tested these changes on platforms I have access to and work with mainline. Signed-of-by: Felipe Balbi <balbi@ti.com>

It separates function logic form physical endpoint addresses making it more hardware independent. Following modifications changes user space API, so to enable them user have to switch on the FUNCTIONFS_VIRTUAL_ADDR flag in descriptors. Endpoints are now refered using virtual endpoint addresses chosen by user in endpoint descpriptors. This applies to each context when endpoint address can be used: - when accessing endpoint files in FunctionFS filesystemi (in file name), - in setup requests directed to specific endpoint (in wIndex field), - in descriptors returned by FUNCTIONFS_ENDPOINT_DESC ioctl. In endpoint file names the endpoint address number is formatted as double-digit hexadecimal value ("ep%02x") which has few advantages - it is easy to parse, allows to easly recognize endpoint direction basing on its name (IN endpoint number starts with digit 8, and OUT with 0) which can be useful for debugging purpose, and it makes easier to introduce further features allowing to use each endpoint number in both directions to have more endpoints available for function if hardware supports this (for example we could have ep01 which is endpoint 1 with OUT direction, and ep81 which is endpoint 1 with IN direction). Physical endpoint address can be still obtained using ioctl named FUNCTIONFS_ENDPOINT_REVMAP, but now it's not neccesary to handle USB transactions properly.

It currently stores them in a v4l2 event during the setup stage, and then copies them from the event structure to the driver internal state structure when the event is dequeued. This two-steps approach isn't necessary. Simplify the driver by storing the needed information in the driver internal state structure directly during the setup stage.

These are related to how the early_tx hrtimer is set up, and it turns out they can be fixed by reducing the timer's slack value from 40 to 25 us. Also, when the callback is ran without taking action, it should be rescheduled 20 us later instead of 50 us.

That's when the kernel's tracing infrastructure comes into play. This patch implements a few initial tracepoints for the dwc3 driver. More traces can be added as necessary in order to ease the task of debugging dwc3. Reviewed-by: Paul Zimmerman <paulz@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
