/**
 * DOC: dTSEC Init sequence
 *
 * To prepare dTSEC block for transfer use the following call sequence:
 *
 * - fman_dtsec_defconfig() - This step is optional and yet recommended. Its
 * use is to obtain the default dTSEC configuration parameters.
 *
 * - Change dtsec configuration in &dtsec_cfg. This structure will be used
 * to customize the dTSEC behavior.
 *
 * - fman_dtsec_init() - Applies the configuration on dTSEC hardware.  Note that
 * dTSEC is initialized while both Tx and Rx are disabled.
 *
 * - fman_dtsec_set_mac_address() - Set the station address (mac address).
 * This is used by dTSEC to match against received packets.
 *
 * - fman_dtsec_adjust_link() - Set the link speed and duplex parameters
 * after the PHY establishes the link.
 *
 * - dtsec_enable_tx() and dtsec_enable_rx() to enable transmission and
 * reception.
 */

/**
 * DOC: dTSEC Graceful stop
 *
 * To temporary stop dTSEC activity use fman_dtsec_stop_tx() and
 * fman_dtsec_stop_rx(). Note that these functions request dTSEC graceful stop
 * but return before this stop is complete.  To query for graceful stop
 * completion use fman_dtsec_get_event() and check DTSEC_IEVENT_GTSC and
 * DTSEC_IEVENT_GRSC bits. Alternatively the dTSEC interrupt mask can be set to
 * enable graceful stop interrupts.
 *
 * To resume operation after graceful stop use fman_dtsec_start_tx() and
 * fman_dtsec_start_rx().
 */

/**
 * DOC: dTSEC interrupt handling
 *
 * This code does not provide an interrupt handler for dTSEC.  Instead this
 * handler should be implemented and registered to the operating system by the
 * caller.  Some primitives for accessing the event status and mask registers
 * are provided.
 *
 * See "dTSEC Events" section for a list of events that dTSEC can generate.
 */

/**
 * DOC: dTSEC Events
 *
 * Interrupt events cause dTSEC event bits to be set.  Software may poll the
 * event register at any time to check for pending interrupts.  If an event
 * occurs and its corresponding enable bit is set in the interrupt mask
 * register, the event also causes a hardware interrupt at the PIC.
 *
 * To poll for event status use the fman_dtsec_get_event() function.
 * To configure the interrupt mask use fman_dtsec_enable_interrupt() and
 * fman_dtsec_disable_interrupt() functions.
 * After servicing a dTSEC interrupt use fman_dtsec_ack_event to reset the
 * serviced event bit.
 *
 * The following events may be signaled by dTSEC hardware:
 *
 * %DTSEC_IEVENT_BABR - Babbling receive error.  This bit indicates that
 * a frame was received with length in excess of the MAC's maximum frame length
 * register.
 *
 * %DTSEC_IEVENT_RXC - Receive control (pause frame) interrupt.  A pause
 * control frame was received while Rx pause frame handling is enabled.
 * Also see fman_dtsec_handle_rx_pause().
 *
 * %DTSEC_IEVENT_MSRO - MIB counter overflow.  The count for one of the MIB
 * counters has exceeded the size of its register.
 *
 * %DTSEC_IEVENT_GTSC - Graceful transmit stop complete.  Graceful stop is now
 * complete. The transmitter is in a stopped state, in which only pause frames
 * can be transmitted.
 * Also see fman_dtsec_stop_tx().
 *
 * %DTSEC_IEVENT_BABT - Babbling transmit error.  The transmitted frame length
 * has exceeded the value in the MAC's Maximum Frame Length register.
 *
 * %DTSEC_IEVENT_TXC - Transmit control (pause frame) interrupt.  his bit
 * indicates that a control frame was transmitted.
 *
 * %DTSEC_IEVENT_TXE - Transmit error.  This bit indicates that an error
 * occurred on the transmitted channel.  This bit is set whenever any transmit
 * error occurs which causes the dTSEC to discard all or part of a frame
 * (LC, CRL, XFUN).
 *
 * %DTSEC_IEVENT_LC - Late collision.  This bit indicates that a collision
 * occurred beyond the collision window (slot time) in half-duplex mode.
 * The frame is truncated with a bad CRC and the remainder of the frame
 * is discarded.
 *
 * %DTSEC_IEVENT_CRL - Collision retry limit.  is bit indicates that the number
 * of successive transmission collisions has exceeded the MAC's half-duplex
 * register's retransmission maximum count.  The frame is discarded without
 * being transmitted and transmission of the next frame commences.  This only
 * occurs while in half-duplex mode.
 * The number of retransmit attempts can be set in
 * &dtsec_halfdup_cfg.@retransmit before calling fman_dtsec_init().
 *
 * %DTSEC_IEVENT_XFUN - Transmit FIFO underrun.  This bit indicates that the
 * transmit FIFO became empty before the complete frame was transmitted.
 * The frame is truncated with a bad CRC and the remainder of the frame is
 * discarded.
 *
 * %DTSEC_IEVENT_MAG - TBD
 *
 * %DTSEC_IEVENT_MMRD - MII management read completion.
 *
 * %DTSEC_IEVENT_MMWR - MII management write completion.
 *
 * %DTSEC_IEVENT_GRSC - Graceful receive stop complete.  It allows the user to
 * know if the system has completed the stop and it is safe to write to receive
 * registers (status, control or configuration registers) that are used by the
 * system during normal operation.
 *
 * %DTSEC_IEVENT_TDPE - Internal data error on transmit.  This bit indicates
 * that the dTSEC has detected a parity error on its stored transmit data, which
 * is likely to compromise the validity of recently transferred frames.
 *
 * %DTSEC_IEVENT_RDPE - Internal data error on receive.  This bit indicates that
 * the dTSEC has detected a parity error on its stored receive data, which is
 * likely to compromise the validity of recently transferred frames.

/**
 * struct dtsec_cfg - dTSEC configuration
 *
 * @halfdup_on:		Transmit half-duplex flow control, under software
 *			control for 10/100-Mbps half-duplex media. If set,
 *			back pressure is applied to media by raising carrier.
 * @halfdup_retransmit:	Number of retransmission attempts following a collision.
 *			If this is exceeded dTSEC aborts transmission due to
 *			excessive collisions. The standard specifies the
 *			attempt limit to be 15.
 * @halfdup_coll_window:The number of bytes of the frame during which
 *			collisions may occur. The default value of 55
 *			corresponds to the frame byte at the end of the
 *			standard 512-bit slot time window. If collisions are
 *			detected after this byte, the late collision event is
 *			asserted and transmission of current frame is aborted.
 * @rx_drop_bcast:	Discard broadcast frames.  If set, all broadcast frames
 *			will be discarded by dTSEC.
 * @rx_short_frm:	Accept short frames.  If set, dTSEC will accept frames
 *			of length 14..63 bytes.
 * @rx_len_check:	Length check for received frames.  If set, the MAC
 *			checks the frame's length field on receive to ensure it
 *			matches the actual data field length. This only works
 *			for received frames with length field less than 1500.
 *			No check is performed for larger frames.
 * @tx_pad_crc:		Pad and append CRC.  If set, the MAC pads all
 *			transmitted short frames and appends a CRC to every
 *			frame regardless of padding requirement.
 * @tx_crc:		Transmission CRC enable.  If set, the MAC appends a CRC
 *			to all frames.  If frames presented to the MAC have a
 *			valid length and contain a valid CRC, @tx_crc should be
 *			reset.
 *			This field is ignored if @tx_pad_crc is set.
 * @rx_ctrl_acc:	Control frame accept.  If set, this overrides 802.3
 *			standard control frame behavior, and all Ethernet frames
 *			that have an ethertype of 0x8808 are treated as normal
 *			Ethernet frames and passed up to the packet interface on
 *			a DA match.  Received pause control frames are passed to
 *			the packet interface only if Rx flow control is also
 *			disabled.  See fman_dtsec_handle_rx_pause() function.
 * @tx_pause_time:	Transmit pause time value.  This pause value is used as
 *			part of the pause frame to be sent when a transmit pause
 *			frame is initiated.  If set to 0 this disables
 *			transmission of pause frames.
 * @rx_preamble:	Receive preamble enable.  If set, the MAC recovers the
 *			received Ethernet 7-byte preamble and passes it to the
 *			packet interface at the start of each received frame.
 *			This field should be reset for internal MAC loop-back
 *			mode.
 * @tx_preamble:	User defined preamble enable for transmitted frames.
 *			If set, a user-defined preamble must passed to the MAC
 *			and it is transmitted instead of the standard preamble.
 * @preamble_len:	Length, in bytes, of the preamble field preceding each
 *			Ethernet start-of-frame delimiter byte.  The default
 *			value of 0x7 should be used in order to guarantee
 *			reliable operation with IEEE 802.3 compliant hardware.
 * @rx_prepend:		Packet alignment padding length.  The specified number
 *			of bytes (1-31) of zero padding are inserted before the
 *			start of each received frame.  For Ethernet, where
 *			optional preamble extraction is enabled, the padding
 *			appears before the preamble, otherwise the padding
 *			precedes the layer 2 header.
 *
 * This structure contains basic dTSEC configuration and must be passed to
 * fman_dtsec_init() function.  A default set of configuration values can be
 * obtained by calling fman_dtsec_defconfig().
