+Subject: [PATCH] arm64: dts: Add DTS files for bcmbca SoC BCM6813
+
+Add DTS for ARMv8 based broadband SoC BCM6813. bcm6813.dtsi is the
+SoC description DTS header and bcm96813.dts is a simple DTS file for
+Broadcom BCM96813 Reference board that only enable the UART port.

+Subject: [PATCH] arm64: dts: Add BCM4908 generic board dts
+
+Add generic bare bone bcm94908.dts file to support any 4908 based
+design. It supports cpu subsystem, memory and an uart console. This can
+be useful for board bring-up and cpu subsystem and memory related kernel
+test as well.

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+1. Define more regs. Some switches (e.g. BCM4908) have up to 6 regs.
+2. Add helper for handling non-lineral port <-> reg mappings.
+3. Add support for 12 B LED reg blocks on BCM4908 (different layout)
+
+Complete support for LEDs setup will be implemented once Linux receives
+a proper design & implementation for "hardware" LEDs.

+Subject: [PATCH] net: broadcom: bcm4908_enet: use build_skb()
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+RX code can be more efficient with the build_skb(). Allocating actual
+SKB around eth packet buffer - right before passing it up - results in
+a better cache usage.
+
+Without RPS (echo 0 > rps_cpus) BCM4908 NAT masq performance "jumps"
+between two speeds: ~900 Mbps and 940 Mbps (it's a 4 CPUs SoC). This
+change bumps the lower speed from 905 Mb/s to 918 Mb/s (tested using
+single stream iperf 2.0.5 traffic).
+
+There are more optimizations to consider. One obvious to try is GRO
+however as BCM4908 doesn't do hw csum is may actually lower performance.
+Sometimes. Some early testing:
+
+┌─────────────────────────────────┬─────────────────────┬────────────────────┐
+│                                 │ netif_receive_skb() │ napi_gro_receive() │
+├─────────────────────────────────┼─────────────────────┼────────────────────┤
+│ netdev_alloc_skb()              │            905 Mb/s │           892 Mb/s │
+│ napi_alloc_frag() + build_skb() │            918 Mb/s │           917 Mb/s │
+└─────────────────────────────────┴─────────────────────┴────────────────────┘
+
+Another ideas:
+1. napi_build_skb()
+2. skb_copy_from_linear_data() for small packets
+
+Those need proper testing first though. That can be done later.

+Subject: [PATCH] pinctrl: bcm: add driver for BCM4908 pinmux
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+BCM4908 has its own pins layout so it needs a custom binding and a Linux
+driver.

+BCM4908 contains NAND controller version 0x0701 (v7.1). It means that
+NAND_WP should be available.
+
+For some reason setting #WP on doesn't result in clearing NAND_STATUS_WP
+status bit:
+[    1.077857] bcm63138_nand ff801800.nand: timeout on status poll (expected c0000040 got c00000c0)
+[    1.086832] bcm63138_nand ff801800.nand: nand #WP expected on
+
+For now try working without touching #WP.
