Since the USB Transceiver and Mentor USB IP controller are on different hardware, API's are defined for the communication between them. These API's are available in ux500.c file. + The ST-Ericsson's USB driver doesn't have the internal DMA dedicated for USB. So, the external system DMA is used. The integration of external DMA with the mentor chip is available in ux500_dma.c file. + Changes have been made in the musb_core.c file where endpoints are configured as per the platform and also integrated DMA specific chnages in the musb_gadget.c file. + <!-- TODO: A brief introduction about the concepts + which are introduced by the driver. + Remove this chapter completely if there are no + special concepts introduced by this driver. + Do NOT change the chapter id or title! --> + <!-- TODO: This guideline for this chapter may be extended + during the user-guide guidelines drop. --> + </para> + </chapter> + + <chapter id="bugs"> + <title>Known Bugs And Assumptions</title> + <!-- Do NOT change the chapter id or title! --> + <para> + <variablelist> + + <varlistentry> + <term>None.</term> + <listitem> + <para> + </para> + </listitem> + </varlistentry> + + </variablelist> + + </para> + </chapter> + <chapter id="pubfunctions"> + <title>Public Functions Provided</title> + <para> + The musb driver doesn't export any functions. + </para> + </chapter> + <chapter id="intfunctions"> + <title>Internal Functions Provided</title> + <para> + List of internal functions + </para> + <!-- Do NOT change the chapter id or title! --> + <!-- TODO: Replace with link to appropriate headerfile(s), + source file(s), or both.
