+Subject: [PATCH 2/2] usb: dwc2:  add support for other Lantiq SoCs
+
+The size of the internal RAM of the DesignWare USB controller changed
+between the different Lantiq SoCs. We have the following sizes:
+
+Amazon + Danube: 8 KByte
+Amazon SE + arx100: 2 KByte
+xrx200 + xrx300: 2.5 KByte
+
+For Danube SoC we do not provide the params and let the driver decide
+to use sane defaults, for the Amazon SE and arx100 we use small fifos
+and for the xrx200 and xrx300 SCs a little bit bigger periodic fifo.
+The auto detection of max_transfer_size and max_packet_count should
+work, so remove it.

+From 14909c4e4e836925668e74fc6e0e85ba0283cbf9 Mon Sep 17 00:00:00 2001
+From: Hauke Mehrtens <hauke@hauke-m.de>
+Date: Fri, 6 Jan 2017 17:40:12 +0100
+Subject: [PATCH 2/2] MIPS: lantiq: improve USB initialization
+
+This adds code to initialize the USB controller and PHY also on Danube,
+Amazon SE and AR10. This code is based on the Vendor driver from
+different UGW versions and compared to the hardware documentation.

+Subject: [PATCH] MIPS: lantiq: enable all hardware interrupts on second VPE
+
+This patch is needed to handle interrupts by the second VPE on the Lantiq
+ARX100, xRX200, xRX300 and xRX330 SoCs. Switching some ICU interrupts to
+the second VPE results in a hang. Currently, the vsmp_init_secondary()
+function is responsible for enabling these interrupts. It only enables
+Malta-specific interrupts (SW0, SW1, HW4 and HW5).
+
+The MIPS core has 8 interrupts defined. On Lantiq SoCs, hardware
+interrupts are wired to an ICU instance. Each VPE has an independent
+instance of the ICU. The mapping of the ICU interrupts is shown below:
+SW0(IP0) - IPI call,
+SW1(IP1) - IPI resched,
+HW0(IP2) - ICU 0-31,
+HW1(IP3) - ICU 32-63,
+HW2(IP4) - ICU 64-95,
+HW3(IP5) - ICU 96-127,
+HW4(IP6) - ICU 128-159,
+HW5(IP7) - timer.
+
+This patch enables all interrupt lines on the second VPE.
+
+This problem affects multithreaded SoCs with a custom interrupt controller.
+SOCs with 1004Kc core and newer use the MIPS GIC. At this point, I am aware
+that the Realtek RTL839x and RTL930x SoCs may need a similar fix. In the
+future, this may be replaced with some generic solution.
+
+Tested on Lantiq xRX200.

+Subject: [PATCH] net: lantiq_xrx200: increase buffer reservation
+
+If the user sets a lower mtu on the CPU port than on the switch,
+then DMA inserts a few more bytes into the buffer than expected.
+In the worst case, it may exceed the size of the buffer. The
+experiments showed that the buffer should be a multiple of the
+burst length value. This patch rounds the length of the rx buffer
+upwards and fixes this bug. The reservation of FCS space in the
+buffer has been removed as PMAC strips the FCS.

+Subject: [PATCH] net: lantiq_xrx200: add ingress SG DMA support
+
+This patch adds support for scatter gather DMA. DMA in PMAC splits
+the packet into several buffers when the MTU on the CPU port is
+less than the MTU of the switch. The first buffer starts at an
+offset of NET_IP_ALIGN. In subsequent buffers, dma ignores the
+offset. Thanks to this patch, the user can still connect to the
+device in such a situation. For normal configurations, the patch
+has no effect on performance.

+Subject: [PATCH] net: dsa: lantiq: allow to use all GPHYs on xRX300 and xRX330
+
+This patch allows to use all PHYs on GRX300 and GRX330. The ARX300
+has 3 and the GRX330 has 4 integrated PHYs connected to different
+ports compared to VRX200. Each integrated PHY can work as single
+Gigabit Ethernet PHY (GMII) or as double Fast Ethernet PHY (MII).
+
+Allowed port configurations:
+
+xRX200:
+GMAC0: RGMII, MII, REVMII or RMII port
+GMAC1: RGMII, MII, REVMII or RMII port
+GMAC2: GPHY0 (GMII)
+GMAC3: GPHY0 (MII)
+GMAC4: GPHY1 (GMII)
+GMAC5: GPHY1 (MII) or RGMII port
+
+xRX300:
+GMAC0: RGMII port
+GMAC1: GPHY2 (GMII)
+GMAC2: GPHY0 (GMII)
+GMAC3: GPHY0 (MII)
+GMAC4: GPHY1 (GMII)
+GMAC5: GPHY1 (MII) or RGMII port
+
+xRX330:
+GMAC0: RGMII, GMII or RMII port
+GMAC1: GPHY2 (GMII)
+GMAC2: GPHY0 (GMII)
+GMAC3: GPHY0 (MII) or GPHY3 (GMII)
+GMAC4: GPHY1 (GMII)
+GMAC5: GPHY1 (MII), RGMII or RMII port
+
+Tested on D-Link DWR966 (xRX330) with OpenWRT.

+Subject: net: dsa: lantiq_gswip: enable jumbo frames on GSWIP
+
+This enables non-standard MTUs on a per-port basis, with the overall
+frame size set based on the CPU port.
+
+When the MTU is not changed, this should have no effect.
+
+Long packets crash the switch with MTUs of greater than 2526, so the
+maximum is limited for now. Medium packets are sometimes dropped (e.g.
+TCP over 2477, UDP over 2516-2519, ICMP over 2526), Hence an MTU value
+of 2400 seems safe.

+Subject: [PATCH 5/5] net: lantiq: configure the burst length in ethernet
+ drivers
+
+Configure the burst length in Ethernet drivers. This improves
+Ethernet performance by 58%. According to the vendor BSP,
+8W burst length is supported by ar9 and newer SoCs.
+
+The NAT benchmark results on xRX200 (Down/Up):
+* 2W: 330 Mb/s
+* 4W: 432 Mb/s    372 Mb/s
+* 8W: 520 Mb/s    389 Mb/s
+
+Tested on xRX200 and xRX330.

+The skb->len field is read after the packet is sent to the network
+stack. In the meantime, skb can be freed. This patch fixes this bug.

+Subject: [PATCH] net: lantiq_xrx200: confirm skb is allocated before using
+
+xrx200_hw_receive() assumes build_skb() always works and goes straight
+to skb_reserve(). However, build_skb() can fail under memory pressure.
+
+Add a check in case build_skb() failed to allocate and return NULL.

+Subject: [PATCH] net: lantiq_xrx200: fix lock under memory pressure
+
+When the xrx200_hw_receive() function returns -ENOMEM, the NAPI poll
+function immediately returns an error.
+This is incorrect for two reasons:
+* the function terminates without enabling interrupts or scheduling NAPI,
+* the error code (-ENOMEM) is returned instead of the number of received
+packets.
+
+After the first memory allocation failure occurs, packet reception is
+locked due to disabled interrupts from DMA..
