The following patches were dropped because they are already applied upstream: - 0038-MIPS-lantiq-fpi-on-ar9.patch - 0039-MIPS-lantiq-initialize-usb-on-boot.patch - 0042-USB-DWC2-big-endian-support.patch - 0043-gpio-stp-xway-fix-phy-mask.patch All other patches were simply refreshed, except the following: - 0001-MIPS-lantiq-add-pcie-driver.patch Changes to arch/mips/lantiq/xway/sysctrl.c (these changes disabled some PMU gates for the vrx200 / VR9 SoCs) were removed since the upstream kernel disables unused PMU gates automatically (since 95135bfa7ead1becc2879230f72583dde2b71a0c "MIPS: Lantiq: Deactivate most of the devices by default"). - 0025-NET-MIPS-lantiq-adds-xrx200-net.patch Since OpenWrt commit 55ba20afcc2fe785146316e5be2c2473cb329885 drivers should use of_get_mac_address(). of_get_mac_address_mtd is not available for drivers anymore since it's called automatically within of_get_mac_address(). - 0028-NET-lantiq-various-etop-fixes.patch Same changes as in 0025-NET-MIPS-lantiq-adds-xrx200-net.patch While refreshing the kernel configuration SPI support had to be moved to config-4.4 because otherwise M25P80 was disabled.
