Subject[PATCH RFC v4 00/10] 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)
* 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()

Stefan Wahren (10):
net: qualcomm: remove unnecessary includes
net: qca_debug: use net_device_ops instead of direct call
net: qualcomm: move qcaspi_tx_cmd to qca_spi.c
net: qualcomm: rename qca_framing.c to qca_common.c
net: qualcomm: prepare frame decoding for UART driver
net: qualcomm: make qca_common a separate kernel module
dt-bindings: net: add binding for QCA7000 UART
net: qualcomm: add QCA7000 UART driver
tty: serdev-ttyport: return actual baudrate from ttyport_set_baudrate
tty: serdev: add functions to retrieve common UART settings
