+Subject: [PATCH] ARM: dts: BCM5301X: correct RX delay and enable flow control
+ on Asus RT-AC88U
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The current 'rx-internal-delay-ps' property value on the Realtek switch
+node, 2000, will be divided by 300, resulting in 6.66, which will be
+rounded to the closest step value, 7. Change it to 2100 to be accurate.
+See ef136837aaf6 ("net: dsa: rtl8365mb: set RGMII RX delay in steps of
+0.3 ns") for reference.
+
+Flow control needs to be enabled on both sides of the internal and
+external switch. It is already enabled on the CPU port of the Realtek
+switch so we also enable it on the external switch port of the Broadcom
+switch as well.

+Subject: [PATCH] ARM: dts: NSP: MX6X: correct LED function types
+
+Currently, the amber LED will remain always on. This is due to a
+misinterpretation of the LED sub-node properties, where-by "default-state"
+was used to indicate the initial state when powering on the device. When in
+use, however, this resulted in the amber LED always being on. Instead change
+this to only indicate a fault state.
+
+Assign LED_FUNCTION_POWER to the green PWM LED.
+
+These changes bring the MX64/65 in line with the MR32's devicetree.

+Subject: [PATCH] ARM: dts: BCM5301X: Add Ethernet MAC address to Luxul
+ XWR-3150
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Luxul XWR-3150 stores MAC as NVRAM variable. Add NVMEM cell for it and
+reference it in the Ethernet interface node.
