Detailed Description

The diagnostic interface will provide access to the controller for bringing up the hardware and testing.

The Linux driver attributes feature will be used to provide the Linux Diagnostic Interface. These attributes are accessed through sysfs.

Function Documentation

ssize_t remote_wakeup_store (  struct device *  _dev, struct device_attribute *  attr, const char *  buf, size_t  count )  [static]

Initiate a remote wakeup of the host. The Device control register Remote Wakeup Signal bit is written if the PCD Remote wakeup enable flag is set. Definition at line 854 of file dwc_otg_attr.c.

ssize_t rem_wakeup_pwrdn_show (  struct device *  _dev, struct device_attribute *  attr, char *  buf )  [static]

Show the whether core is hibernated or not. Definition at line 883 of file dwc_otg_attr.c.

ssize_t hcd_frrem_show (  struct device *  _dev, struct device_attribute *  attr, char *  buf )  [static]

Dump the average frame remaining at SOF. This can be used to determine average interrupt latency. Frame remaining is also shown for start transfer and two additional sample points. Definition at line 1023 of file dwc_otg_attr.c.
