net: qualcomm: add QCA7000 UART driver
The Qualcomm QCA7000 HomePlug GreenPHY supports two interfaces:
UART and SPI. 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)

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
