+SMSC/MicroChip LAN9303 three port ethernet switch
+-------------------------------------------------
+
+Required properties:
+
+- compatible: should be
+ - "smsc,lan9303-i2c" for I2C managed mode
+ or
+ - "smsc,lan9303-mdio" for mdio managed mode
+
+Optional properties:
+
+- reset-gpios: GPIO to be used to reset the whole device
+- reset-duration: reset duration in milliseconds, defaults to 200 ms
+
+Subnodes:
+
+The integrated switch subnode should be specified according to the binding
+described in dsa/dsa.txt. The CPU port of this switch is always port 0.
+
+Note: always use 'reg = <0/1/2>;' for the three DSA ports, even if the device is
+configured to use 1/2/3 instead. This hardware configuration will be
+auto-detected and mapped accordingly.
+
+Example:
+
+I2C managed mode:
+
+ master: masterdevice@X {
+ status = "okay";
+
+ fixed-link { /* RMII fixed link to LAN9303 */
+ speed = <100>;
+ full-duplex;
+ };
+ };
+
+ switch: switch@a {
+ compatible = "smsc,lan9303-i2c";
+ reg = <0xa>;
+ status = "okay";
+ reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
+ reset-duration = <200>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 { /* RMII fixed link to master */
+ reg = <0>;
+ label = "cpu";
+ ethernet = <&master>;
+ };
+
+ port@1 { /* external port 1 */
+ reg = <1>;
+ label = "lan1;
+ };
+
+ port@2 { /* external port 2 */
+ reg = <2>;
+ label = "lan2";
+ };
+ };
+ };
+
+MDIO managed mode:
+
+ master: masterdevice@X {
+ status = "okay";
+ phy-handle = <&switch>;
+
+ mdio {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ switch: switch-phy@0 {
+ compatible = "smsc,lan9303-mdio";
+ reg = <0>;
+ reset-gpios = <&gpio7 6 GPIO_ACTIVE_LOW>;
+ reset-duration = <100>;
+
+ ports {
+ #address-cells = <1>;
+ #size-cells = <0>;
+
+ port@0 {
+ reg = <0>;
+ label = "cpu";
+ ethernet = <&master>;
+ };
+
+ port@1 { /* external port 1 */
+ reg = <1>;
+ label = "lan1;
+ };
+
+ port@2 { /* external port 2 */
+ reg = <2>;
+ label = "lan2";
+ };
+ };
+ };
+ };
+ };
- interrupt-parent: Should be the phandle for the interrupt controller
that services interrupts for this device
- interrupts: Should contain the STMMAC interrupts
-- interrupt-names: Should contain the interrupt names "macirq"
- "eth_wake_irq" if this interrupt is supported in the "interrupts"
- property
+- interrupt-names: Should contain a list of interrupt names corresponding to
+ the interrupts in the interrupts property, if available.
+ Valid interrupt names are:
+ - "macirq" (combined signal for various interrupt events)
+ - "eth_wake_irq" (the interrupt to manage the remote wake-up packet detection)
+ - "eth_lpi" (the interrupt that occurs when Tx or Rx enters/exits LPI state)
- phy-mode: See ethernet.txt file in the same directory.
- snps,reset-gpio gpio number for phy reset.
- snps,reset-active-low boolean flag to indicate if phy reset is active low.

+ * DOC: FILS shared key authentication offload
+ *
+ * FILS shared key authentication offload can be advertized by drivers by
+ * setting @NL80211_EXT_FEATURE_FILS_SK_OFFLOAD flag. The drivers that support
+ * FILS shared key authentication offload should be able to construct the
+ * authentication and association frames for FILS shared key authentication and
+ * eventually do a key derivation as per IEEE 802.11ai. The below additional
+ * parameters should be given to driver in %NL80211_CMD_CONNECT.
+ * %NL80211_ATTR_FILS_ERP_USERNAME - used to construct keyname_nai
+ * %NL80211_ATTR_FILS_ERP_REALM - used to construct keyname_nai
+ * %NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used to construct erp message
+ * %NL80211_ATTR_FILS_ERP_RRK - used to generate the rIK and rMSK
+ * rIK should be used to generate an authentication tag on the ERP message and
+ * rMSK should be used to derive a PMKSA.
+ * rIK, rMSK should be generated and keyname_nai, sequence number should be used
+ * as specified in IETF RFC 6696.
+ *
+ * When FILS shared key authentication is completed, driver needs to provide the
+ * below additional parameters to userspace.
+ * %NL80211_ATTR_FILS_KEK - used for key renewal
+ * %NL80211_ATTR_FILS_ERP_NEXT_SEQ_NUM - used in further EAP-RP exchanges
+ * %NL80211_ATTR_PMKID - used to identify the PMKSA used/generated
+ * %Nl80211_ATTR_PMK - used to update PMKSA cache in userspace
+ * The PMKSA can be maintained in userspace persistently so that it can be used
+ * later after reboots or wifi turn off/on also.
+ *
+ * %NL80211_ATTR_FILS_CACHE_ID is the cache identifier advertized by a FILS
+ * capable AP supporting PMK caching. It specifies the scope within which the
+ * PMKSAs are cached in an ESS. %NL80211_CMD_SET_PMKSA and
+ * %NL80211_CMD_DEL_PMKSA are enhanced to allow support for PMKSA caching based
+ * on FILS cache identifier. Additionally %NL80211_ATTR_PMK is used with
+ * %NL80211_SET_PMKSA to specify the PMK corresponding to a PMKSA for driver to
