Name Description Access
mode Returns the current mode: 0 for device mode, 1 for host mode Read
hnpcapable Gets or sets the "HNP-capable" bit in the Core USB Configuraton Register. ++ Read returns the current value. Read/Write
srpcapable Gets or sets the "SRP-capable" bit in the Core USB Configuraton Register. ++ Read returns the current value. Read/Write
hnp Initiates the Host Negotiation Protocol. Read returns the status. Read/Write
srp Initiates the Session Request Protocol. Read returns the status. Read/Write
buspower Gets or sets the Power State of the bus (0 - Off or 1 - On) Read/Write
bussuspend Suspends the USB bus. Read/Write
busconnected Gets the connection status of the bus Read
gotgctl Gets or sets the Core Control Status Register. Read/Write
gusbcfg Gets or sets the Core USB Configuration Register Read/Write
grxfsiz Gets or sets the Receive FIFO Size Register Read/Write
gnptxfsiz Gets or sets the non-periodic Transmit Size Register Read/Write
gpvndctl Gets or sets the PHY Vendor Control Register Read/Write
ggpio Gets the value in the lower 16-bits of the General Purpose IO Register ++ or sets the upper 16 bits. Read/Write
guid Gets or sets the value of the User ID Register Read/Write
gsnpsid Gets the value of the Synopsys ID Regester Read
devspeed Gets or sets the device speed setting in the DCFG register Read/Write
enumspeed Gets the device enumeration Speed. Read
hptxfsiz Gets the value of the Host Periodic Transmit FIFO Read
hprt0 Gets or sets the value in the Host Port Control and Status Register Read/Write
regoffset Sets the register offset for the next Register Access Read/Write
regvalue Gets or sets the value of the register at the offset in the regoffset attribute. Read/Write
remote_wakeup On read, shows the status of Remote Wakeup. On write, initiates a remote ++ wakeup of the host. When bit 0 is 1 and Remote Wakeup is enabled, the Remote ++ Wakeup signalling bit in the Device Control Register is set for 1 ++ milli-second. Read/Write
regdump Dumps the contents of core registers. Read
hcddump Dumps the current HCD state. Read
hcd_frrem Shows the average value of the Frame Remaining ++ field in the Host Frame Number/Frame Remaining register when an SOF interrupt ++ occurs. This can be used to determine the average interrupt latency. Also ++ shows the average Frame Remaining value for start_transfer and the "a" and ++ "b" sample points. The "a" and "b" sample points may be used during debugging ++ bto determine how long it takes to execute a section of the HCD code. Read
rd_reg_test Displays the time required to read the GNPTXFSIZ register many times ++ (the output shows the number of times the register is read). ++ Read
wr_reg_test Displays the time required to write the GNPTXFSIZ register many times ++ (the output shows the number of times the register is written). ++ Read

It also handles basic tasks like ++ * reading/writing the registers and data FIFOs in the controller. ++ * Some of the data access functions provide encapsulation of several ++ * operations required to perform a task, such as writing multiple ++ * registers to start a transfer. Finally, the CIL performs basic ++ * services that are not specific to either the host or device modes ++ * of operation. These services include management of the OTG Host ++ * Negotiation Protocol (HNP) and Session Request Protocol (SRP). A ++ * Diagnostic API is also provided to allow testing of the controller ++ * hardware. ++ * ++ * The Core Interface Layer has the following requirements: ++ * - Provides basic controller operations. ++ * - Minimal use of OS services. ++ * - The OS services used will be abstracted by using inline functions ++ * or macros. ++ * ++ */ ++#include ++ ++#ifdef DEBUG ++#include ++#endif ++ ++#include "dwc_otg_plat.h" ++ ++#include "dwc_otg_regs.h" ++#include "dwc_otg_cil.h" ++ ++/** ++ * This function is called to initialize the DWC_otg CSR data ++ * structures.

This module will be dynamically installed ++ * after Linux is booted using the insmod command. When the module is ++ * installed, the dwc_otg_init function is called. When the module is ++ * removed (using rmmod), the dwc_otg_cleanup function is called. ++ * ++ * This module also defines a data structure for the dwc_otg_driver, which is ++ * used in conjunction with the standard ARM lm_device structure.
