Subject: [PATCH RFC v4 00/10] net: qualcomm: add QCA7000 UART driver
Date: Mon, 27 Mar 2017 15:37:18 +0200	[thread overview]
Message-ID: <1490621848-24828-1-git-send-email-stefan.wahren@i2se.com> (raw)

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. Patches 4 - 7 prepare the existing QCA7000
code for UART support. Patch 8 contains the new driver. The last
two patches are suggested improvements for serial device bus.

The code itself has been tested on a Freescale i.MX28 board and
a Raspberry Pi Zero.

Changes in v4:
  * rebase to current linux-next
  * use parameter -M for git format-patch
  * change order of local variables where possible
  * implement basic serdev support (without hardware flow control)

Changes in v3:
  * rebase to current net-next

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