Normally an operating system will probe hardware, - * initialize anything found, and then enable the hardware. - * - * In the probe phase you should: - * - Use cvmx_usb_get_num_ports() to determine the number of - * USB port to be supported. - * - Allocate space for a struct cvmx_usb_state for each - * port. - * - Tell the operating system about each port - * - * In the initialization phase you should: - * - Use cvmx_usb_initialize() on each port. - * - Do not call cvmx_usb_enable(). This leaves the USB port in - * the disabled state until the operating system is ready. - * - * Finally, in the enable phase you should: - * - Call cvmx_usb_enable() on the appropriate port. - * - Note that some operating system use a RESET instead of an - * enable call. To implement RESET, you should call - * cvmx_usb_disable() followed by cvmx_usb_enable(). - * - * == Locking == - * - * All of the functions in the cvmx-usb API assume exclusive - * access to the USB hardware and internal data structures. This - * means that the driver must provide locking as necessary. - * - * In the single CPU state it is normally enough to disable - * interrupts before every call to cvmx_usb*() and enable them - * again after the call is complete. Keep in mind that it is - * very common for the callback handlers to make additional - * calls into cvmx-usb, so the disable/enable must be protected - * against recursion. As an example, the Linux kernel - * local_irq_save() and local_irq_restore() are perfect for this - * in the non SMP case. - * - * In the SMP case, locking is more complicated. For SMP you not - * only need to disable interrupts on the local core, but also - * take a lock to make sure that another core cannot call - * cvmx-usb. - * - * == Port callback == - * - * The port callback prototype needs to look as follows: - * - * void port_callback(struct cvmx_usb_state *usb, - * enum cvmx_usb_callback reason, - * enum cvmx_usb_complete status, - * int pipe_handle, - * int submit_handle, - * int bytes_transferred, - * void *user_data); - * - "usb" is the struct cvmx_usb_state for the port. - * - "reason" will always be CVMX_USB_CALLBACK_PORT_CHANGED. - * - "status" will always be CVMX_USB_COMPLETE_SUCCESS. - * - "pipe_handle" will always be -1. - * - "submit_handle" will always be -1. - * - "bytes_transferred" will always be 0. - * - "user_data" is the void pointer originally passed along - * with the callback. Use this for any state information you - * need. - * - * The port callback will be called whenever the user plugs / - * unplugs a device from the port. It will not be called when a - * device is plugged / unplugged from a hub connected to the - * root port. Normally all the callback needs to do is tell the - * operating system to poll the root hub for status. Under - * Linux, this is performed by calling usb_hcd_poll_rh_status(). - * In the Linux driver we use "user_data". to pass around the - * Linux "hcd" structure. Once the port callback completes, - * Linux automatically calls octeon_usb_hub_status_data() which - * uses cvmx_usb_get_status() to determine the root port status. - * - * == Complete callback == - * - * The completion callback prototype needs to look as follows: - * - * void complete_callback(struct cvmx_usb_state *usb, - * enum cvmx_usb_callback reason, - * enum cvmx_usb_complete status, - * int pipe_handle, - * int submit_handle, - * int bytes_transferred, - * void *user_data); - * - "usb" is the struct cvmx_usb_state for the port. - * - "reason" will always be CVMX_USB_CALLBACK_TRANSFER_COMPLETE. - * - "status" will be one of the cvmx_usb_complete enumerations. - * - "pipe_handle" is the handle to the pipe the transaction - * was originally submitted on. - * - "submit_handle" is the handle returned by the original - * cvmx_usb_submit_* call. - * - "bytes_transferred" is the number of bytes successfully - * transferred in the transaction. This will be zero on most - * error conditions. - * - "user_data" is the void pointer originally passed along - * with the callback. Use this for any state information you - * need. For example, the Linux "urb" is stored in here in the - * Linux driver. - * - * In general your callback handler should use "status" and - * "bytes_transferred" to tell the operating system the how the - * transaction completed. Normally the pipe is not changed in - * this callback. - * - * == Canceling transactions == - * - * When a transaction is cancelled using cvmx_usb_cancel*(), the - * actual length of time until the complete callback is called - * can vary greatly. It may be called before cvmx_usb_cancel*() - * returns, or it may be called a number of usb frames in the - * future once the hardware frees the transaction. In either of - * these cases, the complete handler will receive - * CVMX_USB_COMPLETE_CANCEL. - * - * == Handling pipes == - * - * USB "pipes" is a software construct created by this API to - * enable the ordering of usb transactions to a device endpoint. - * Octeon's underlying hardware doesn't have any concept - * equivalent to "pipes". The hardware instead has eight - * channels that can be used simultaneously to have up to eight - * transaction in process at the same time. In order to maintain - * ordering in a pipe, the transactions for a pipe will only be - * active in one hardware channel at a time. From an API user's - * perspective, this doesn't matter but it can be helpful to - * keep this in mind when you are probing hardware while - * debugging. - * - * Also keep in mind that usb transactions contain state - * information about the previous transaction to the same - * endpoint. Each transaction has a PID toggle that changes 0/1 - * between each sub packet. This is maintained in the pipe data - * structures. For this reason, you generally cannot create and - * destroy a pipe for every transaction. A sequence of - * transaction to the same endpoint must use the same pipe. - * - * == Root Hub == - * - * Some operating systems view the usb root port as a normal usb - * hub. These systems attempt to control the root hub with - * messages similar to the usb 2.0 spec for hub control and - * status. For these systems it may be necessary to write - * function to decode standard usb control messages into - * equivalent cvmx-usb API calls. - * - * == Interrupts == - * - * If you plan on using usb interrupts, cvmx_usb_poll() must be - * called on every usb interrupt. It will read the usb state, - * call any needed callbacks, and schedule transactions as - * needed. Your device driver needs only to hookup an interrupt - * handler and call cvmx_usb_poll(). Octeon's usb port 0 causes - * CIU bit CIU_INT*_SUM0[USB] to be set (bit 56). For port 1, - * CIU bit CIU_INT_SUM1[USB1] is set (bit 17). How these bits - * are turned into interrupt numbers is operating system - * specific. For Linux, there are the convenient defines - * OCTEON_IRQ_USB0 and OCTEON_IRQ_USB1 for the IRQ numbers. - * - * If you aren't using interrupts, simple call cvmx_usb_poll() - * in your main processing loop. - */ - -#ifndef __CVMX_USB_H__ -#define __CVMX_USB_H__ - -/** - * enum cvmx_usb_speed - the possible USB device speeds - * - * @CVMX_USB_SPEED_HIGH: Device is operation at 480Mbps - * @CVMX_USB_SPEED_FULL: Device is operation at 12Mbps - * @CVMX_USB_SPEED_LOW: Device is operation at 1.5Mbps - */ -enum cvmx_usb_speed { - CVMX_USB_SPEED_HIGH = 0, - CVMX_USB_SPEED_FULL = 1, - CVMX_USB_SPEED_LOW = 2, -}; - -/** - * enum cvmx_usb_transfer - the possible USB transfer types - * - * @CVMX_USB_TRANSFER_CONTROL: USB transfer type control for hub and status - * transfers - * @CVMX_USB_TRANSFER_ISOCHRONOUS: USB transfer type isochronous for low - * priority periodic transfers - * @CVMX_USB_TRANSFER_BULK: USB transfer type bulk for large low priority - * transfers - * @CVMX_USB_TRANSFER_INTERRUPT: USB transfer type interrupt for high priority - * periodic transfers - */ -enum cvmx_usb_transfer { - CVMX_USB_TRANSFER_CONTROL = 0, - CVMX_USB_TRANSFER_ISOCHRONOUS = 1, - CVMX_USB_TRANSFER_BULK = 2, - CVMX_USB_TRANSFER_INTERRUPT = 3, -}; - -/** - * enum cvmx_usb_direction - the transfer directions - * - * @CVMX_USB_DIRECTION_OUT: Data is transferring from Octeon to the device/host - * @CVMX_USB_DIRECTION_IN: Data is transferring from the device/host to Octeon - */ -enum cvmx_usb_direction { - CVMX_USB_DIRECTION_OUT, - CVMX_USB_DIRECTION_IN, -}; - -/** - * enum cvmx_usb_complete - possible callback function status codes - * - * @CVMX_USB_COMPLETE_SUCCESS: The transaction / operation finished without - * any errors - * @CVMX_USB_COMPLETE_SHORT: FIXME: This is currently not implemented - * @CVMX_USB_COMPLETE_CANCEL: The transaction was canceled while in flight by - * a user call to cvmx_usb_cancel - * @CVMX_USB_COMPLETE_ERROR: The transaction aborted with an unexpected - * error status - * @CVMX_USB_COMPLETE_STALL: The transaction received a USB STALL response - * from the device - * @CVMX_USB_COMPLETE_XACTERR: The transaction failed with an error from the - * device even after a number of retries - * @CVMX_USB_COMPLETE_DATATGLERR: The transaction failed with a data toggle - * error even after a number of retries - * @CVMX_USB_COMPLETE_BABBLEERR: The transaction failed with a babble error - * @CVMX_USB_COMPLETE_FRAMEERR: The transaction failed with a frame error - * even after a number of retries - */ -enum cvmx_usb_complete { - CVMX_USB_COMPLETE_SUCCESS, - CVMX_USB_COMPLETE_SHORT, - CVMX_USB_COMPLETE_CANCEL, - CVMX_USB_COMPLETE_ERROR, - CVMX_USB_COMPLETE_STALL, - CVMX_USB_COMPLETE_XACTERR, - CVMX_USB_COMPLETE_DATATGLERR, - CVMX_USB_COMPLETE_BABBLEERR, - CVMX_USB_COMPLETE_FRAMEERR, -}; - -/** - * struct cvmx_usb_port_status - the USB port status information - * - * @port_enabled: 1 = Usb port is enabled, 0 = disabled - * @port_over_current: 1 = Over current detected, 0 = Over current not - * detected.
