/**
- * dwc3_gadget_start_config - configure ep resources
- * @dep: endpoint that is being enabled
- *
- * Issue a %DWC3_DEPCMD_DEPSTARTCFG command to @dep. After the command's
- * completion, it will set Transfer Resource for all available endpoints.
- *
- * The assignment of transfer resources cannot perfectly follow the data book
- * due to the fact that the controller driver does not have all knowledge of the
- * configuration in advance. It is given this information piecemeal by the
- * composite gadget framework after every SET_CONFIGURATION and
- * SET_INTERFACE. Trying to follow the databook programming model in this
- * scenario can cause errors. For two reasons:
- *
- * 1) The databook says to do %DWC3_DEPCMD_DEPSTARTCFG for every
- * %USB_REQ_SET_CONFIGURATION and %USB_REQ_SET_INTERFACE (8.1.5). This is
- * incorrect in the scenario of multiple interfaces.
- *
- * 2) The databook does not mention doing more %DWC3_DEPCMD_DEPXFERCFG for new
- * endpoint on alt setting (8.1.6).
- *
- * The following simplified method is used instead:
+ * dwc3_gadget_start_config - reset endpoint resources
+ * @dwc: pointer to the DWC3 context
+ * @resource_index: DEPSTARTCFG.XferRscIdx value (must be 0 or 2)
*
- * All hardware endpoints can be assigned a transfer resource and this setting
- * will stay persistent until either a core reset or hibernation. So whenever we
- * do a %DWC3_DEPCMD_DEPSTARTCFG(0) we can go ahead and do
- * %DWC3_DEPCMD_DEPXFERCFG for every hardware endpoint as well. We are
- * guaranteed that there are as many transfer resources as endpoints.
+ * Set resource_index=0 to reset all endpoints' resources allocation. Do this as
+ * part of the power-on/soft-reset initialization.
*
- * This function is called for each endpoint when it is being enabled but is
- * triggered only when called for EP0-out, which always happens first, and which
- * should only happen in one of the above conditions.
+ * Set resource_index=2 to reset only non-control endpoints' resources. Do this
+ * on receiving the SET_CONFIGURATION request or hibernation resume.
