This patch series adds the missing support for UART. This driver based on the Qualcomm code [1], but contains some changes: * use random MAC address per default * use net_device_stats from device * share frame decoding between SPI and UART driver * improve error handling * reimplement tty_wakeup with work queue (based on slcan) * use new serial device bus instead of ldisc The patches 1 - 3 are just for clean up and are not related to the UART support. Patch 4 adds SET_NETDEV_DEV() to qca_spi. Patches 5 - 16 prepare the existing QCA7000 code for UART support. The last patch contains the new driver. The code itself has been tested on a Freescale i.MX28 board and a Raspberry Pi Zero. Changes in v8: * add necessary header includes to qca_7k.c in order to reflect dependencies Changes in v7: * fix race between tx workqueue and device deregistration (reported by Lino) ==================== Signed-off-by: David S.
