+Subject: [PATCH] mtd: nand: add Winbond manufacturer and chip
+
+This patch adds the W25N01GV NAND to the table of
+known devices. Without this patch the device gets detected:
+
+nand: device found, Manufacturer ID: 0xef, Chip ID: 0xaa
+nand: Unknown NAND 256MiB 1,8V 8-bit
+nand: 256 MiB, SLC, erase size: 64 KiB, page size: 1024, OOB size : 16
+
+Whereas the u-boot identifies it as:
+spi_nand: spi_nand_flash_probe SF NAND ID 00:ef:aa:21
+SF: Detected W25N01GV with page size 2 KiB, total 128 MiB
+
+Due to the page size discrepancy, it's impossible to attach
+ubi volumes on the device.

+Subject: mtd: spi-nor: add mx25l25635f with SECT_4K
+
+This patch fixes an issue with the creation of the
+ubi volume on the AVM FRITZ!Box 4040. The mx25l25635f
+and mx25l25635e support SECT_4K which will set the
+erase size to 4K. This is used by ubi to calculate
+VID header offsets. Without this, uboot and linux
+disagrees about the layout and refuse to attach
+the ubi volume created by the other.

+Subject: [PATCH 16/38] mtd: ubi: add auto_attach HACK for the ASUS RT-AC58U
+
+This patch adds a hack that allows UBI's autoattach feature
+to work with the custom ASUS UBI_DEV partition name.
+
+This is necessary because the vendor's u-boot doesn't leave
+the bootargs / cmdline alone, so the it can't be overwritten
+easily otherwise.

+Subject: [PATCH] dts: ipq4019: add mdio node for ethernet
+
+This patch adds the mdio device-tree node.
+This is where the switch is connected to, so it's needed
+for the ethernet interfaces.
+
+Note: The driver isn't anywhere close to be upstream,
+so the info might change.

+Subject: [PATCH 37/38] usb: dwc3: register qca,ipq4019-dwc3 in dwc3-of-simple
+
+For host mode, the dwc3 found in the IPQ4019 can be driven
+by the dwc3-of-simple module. It will get more tricky for
+OTG since they'll need to enable VBUS and reconfigure the
+registers.
