+This document describes the device tree bindings associated with the
+keystone network coprocessor(NetCP) driver support.
+
+The network coprocessor (NetCP) is a hardware accelerator that processes
+Ethernet packets. NetCP has a gigabit Ethernet (GbE) subsytem with a ethernet
+switch sub-module to send and receive packets. NetCP also includes a packet
+accelerator (PA) module to perform packet classification operations such as
+header matching, and packet modification operations such as checksum
+generation. NetCP can also optionally include a Security Accelerator (SA)
+capable of performing IPSec operations on ingress/egress packets.
+
+Keystone II SoC's also have a 10 Gigabit Ethernet Subsystem (XGbE) which
+includes a 3-port Ethernet switch sub-module capable of 10Gb/s and 1Gb/s rates
+per Ethernet port.
+
+Keystone NetCP driver has a plug-in module architecture where each of the NetCP
+sub-modules exist as a loadable kernel module which plug in to the netcp core.
+These sub-modules are represented as "netcp-devices" in the dts bindings. It is
+mandatory to have the ethernet switch sub-module for the ethernet interface to
+be operational. Any other sub-module like the PA is optional.
+
+NetCP Ethernet SubSystem Layout:
+

+
+
+NetCP subsystem properties:
+Required properties:

+- dma-id: Navigator packet dma instance id.
+
+Optional properties:
+- reg: register location and the size for the following register
+ regions in the specified order.
+ - Efuse MAC address register
+- dma-coherent: Present if dma operations are coherent
+- big-endian: Keystone devices can be operated in a mode where the DSP is in
+ the big endian mode. In such cases enable this option. This
+ option should also be enabled if the ARM is operated in
+ big endian mode with the DSP in little endian.
+
+NetCP device properties: Device specification for NetCP sub-modules.
+1Gb/10Gb (gbe/xgbe) ethernet switch sub-module specifications.
+Required properties:
+- label: Must be "netcp-gbe" for 1Gb & "netcp-xgbe" for 10Gb.

+- interfaces: specification for each of the switch port to be registered as a
+ network interface in the stack.
+-- slave-port: Switch port number, 0 based numbering.
+-- link-interface: type of link interface, supported options are
+ - mac<->mac auto negotiate mode: 0

+ - 10Gb mac<->phy mode : 10
+ - 10Gb mac<->mac forced mode : 11
+----phy-handle: phandle to PHY device
+
+Optional properties:
+- enable-ale: NetCP driver keeps the address learning feature in the ethernet
+ switch module disabled. This attribute is to enable the address
+ learning.
+- secondary-slave-ports: specification for each of the switch port not be
+ registered as a network interface. NetCP driver
+ will only initialize these ports and attach PHY
+ driver to them if needed.
+
+NetCP interface properties: Interface specification for NetCP sub-modules.
+Required properties:
+- rx-channel: the navigator packet dma channel name for rx.
+- rx-queue: the navigator queue number associated with rx dma channel.
+- rx-pool: specifies the number of descriptors to be used & the region-id
+ for creating the rx descriptor pool.
+- tx-pool: specifies the number of descriptors to be used & the region-id
+ for creating the tx descriptor pool.
+- rx-queue-depth: number of descriptors in each of the free descriptor
+ queue (FDQ) for the pktdma Rx flow. There can be at
+ present a maximum of 4 queues per Rx flow.
+- rx-buffer-size: the buffer size for each of the Rx flow FDQ.
+- tx-completion-queue: the navigator queue number where the descriptors are
+ recycled after Tx DMA completion.
+
+Optional properties:
+- efuse-mac: If this is 1, then the MAC address for the interface is
+ obtained from the device efuse mac address register
+- local-mac-address: the driver is designed to use the of_get_mac_address api
+ only if efuse-mac is 0. When efuse-mac is 0, the MAC
+ address is obtained from local-mac-address. If this
+ attribute is not present, then the driver will use a
+ random MAC address.
+- "netcp-device label": phandle to the device specification for each of NetCP
+ sub-module attached to this interface.

+Unique flow identifiers
+-----------------------
+
+An alternative to using the original match portion of a key as the handle for
+flow identification is a unique flow identifier, or "UFID". UFIDs are optional
+for both the kernel and user space program.
+
+User space programs that support UFID are expected to provide it during flow
+setup in addition to the flow, then refer to the flow using the UFID for all
+future operations. The kernel is not required to index flows by the original
+flow key if a UFID is specified.

Basic rule for evolving flow keys

-/* T5 and later support a new BAR2-based doorbell mechanism for Egress Queues.
- * The User Doorbells are each 128 bytes in length with a Simple Doorbell at
- * offsets 8x and a Write Combining single 64-byte Egress Queue Unit
- * (X_IDXSIZE_UNIT) Gather Buffer interface at offset 64. For Ingress Queues,
- * we have a Going To Sleep register at offsets 8x+4.
- *
- * As noted above, we have many instances of the Simple Doorbell and Going To
- * Sleep registers at offsets 8x and 8x+4, respectively. We want to use a
- * non-64-byte aligned offset for the Simple Doorbell in order to attempt to
- * avoid buffering of the writes to the Simple Doorbell and we want to use a
- * non-contiguous offset for the Going To Sleep writes in order to avoid
- * possible combining between them.

- * From "Implementing a dynamic compressed trie" by Stefan Nilsson of

- * Telecommunications, page 6:
- * "A node is doubled if the ratio of non-empty children to all
- * children in the *doubled* node is at least 'high'."
- *
- * 'high' in this instance is the variable 'inflate_threshold'. It
- * is expressed as a percentage, so we multiply it with
- * tnode_child_length() and instead of multiplying by 2 (since the
- * child array will be doubled by inflate()) and multiplying
- * the left-hand side by 100 (to handle the percentage thing) we
- * multiply the left-hand side by 50.
- *
- * The left-hand side may look a bit weird: tnode_child_length(tn)
- * - tn->empty_children is of course the number of non-null children
- * in the current node. tn->full_children is the number of "full"
- * children, that is non-null tnodes with a skip value of 0.
- * All of those will be doubled in the resulting inflated tnode, so
- * we just count them one extra time here.
- *
- * A clearer way to write this would be:
- *
- * to_be_doubled = tn->full_children;
- * not_to_be_doubled = tnode_child_length(tn) - tn->empty_children -
- * tn->full_children;
- *
- * new_child_length = tnode_child_length(tn) * 2;
- *
- * new_fill_factor = 100 * (not_to_be_doubled + 2*to_be_doubled) /
- * new_child_length;
- * if (new_fill_factor >= inflate_threshold)
- *
- * ...and so on, tho it would mess up the while () loop.
- *
- * anyway,
- * 100 * (not_to_be_doubled + 2*to_be_doubled) / new_child_length >=
- * inflate_threshold
- *
- * avoid a division:
- * 100 * (not_to_be_doubled + 2*to_be_doubled) >=
- * inflate_threshold * new_child_length
- *
- * expand not_to_be_doubled and to_be_doubled, and shorten:
- * 100 * (tnode_child_length(tn) - tn->empty_children +
- * tn->full_children) >= inflate_threshold * new_child_length
- *
- * expand new_child_length:
- * 100 * (tnode_child_length(tn) - tn->empty_children +
- * tn->full_children) >=
- * inflate_threshold * tnode_child_length(tn) * 2
- *
- * shorten again:

+ * "A node is doubled if the ratio of non-empty children to all
+ * children in the *doubled* node is at least 'high'."
+ *
+ * 'high' in this instance is the variable 'inflate_threshold'. It
+ * is expressed as a percentage, so we multiply it with
+ * tnode_child_length() and instead of multiplying by 2 (since the
+ * child array will be doubled by inflate()) and multiplying
+ * the left-hand side by 100 (to handle the percentage thing) we
+ * multiply the left-hand side by 50.
+ *
+ * The left-hand side may look a bit weird: tnode_child_length(tn)
+ * - tn->empty_children is of course the number of non-null children
+ * in the current node. tn->full_children is the number of "full"
+ * children, that is non-null tnodes with a skip value of 0.
+ * All of those will be doubled in the resulting inflated tnode, so
+ * we just count them one extra time here.
+ *
+ * A clearer way to write this would be:
+ *
+ * to_be_doubled = tn->full_children;
+ * not_to_be_doubled = tnode_child_length(tn) - tn->empty_children -
+ * tn->full_children;
+ *
+ * new_child_length = tnode_child_length(tn) * 2;
+ *
+ * new_fill_factor = 100 * (not_to_be_doubled + 2*to_be_doubled) /
+ * new_child_length;
+ * if (new_fill_factor >= inflate_threshold)
+ *
+ * ...and so on, tho it would mess up the while () loop.
+ *
+ * anyway,
+ * 100 * (not_to_be_doubled + 2*to_be_doubled) / new_child_length >=
+ * inflate_threshold
+ *
+ * avoid a division:
+ * 100 * (not_to_be_doubled + 2*to_be_doubled) >=
+ * inflate_threshold * new_child_length
+ *
+ * expand not_to_be_doubled and to_be_doubled, and shorten:
+ * 100 * (tnode_child_length(tn) - tn->empty_children +
+ * tn->full_children) >= inflate_threshold * new_child_length
+ *
+ * expand new_child_length:
+ * 100 * (tnode_child_length(tn) - tn->empty_children +
+ * tn->full_children) >=
+ * inflate_threshold * tnode_child_length(tn) * 2
+ *
+ * shorten again:
