Subject[PATCH v3 net-next 0/8] net: qualcomm: add QCA7000 UART driver
Date
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)

The patches 1 - 3 are just for clean up and are not related to
the UART support. Patches 4 - 7 prepare the existing QCA7000
code for UART support. The last patch contains the new driver.

In order to test the driver a modified slattach in userspace is also
required. A prepared busybox (includes slattach) can be found here [2].

The code itself has been tested on a Freescale i.MX28 board.

Changes in v3:
* rebase to current net-next

Changes in v2:
* fix build issue by using netif_trans_update() and dev_trans_start()
