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() [1] - https://github.com/IoE/qca7000 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 .../devicetree/bindings/net/qca-qca7000-uart.txt | 31 ++ drivers/net/ethernet/qualcomm/Kconfig | 18 +- drivers/net/ethernet/qualcomm/Makefile | 7 +- drivers/net/ethernet/qualcomm/qca_7k.c | 28 -- drivers/net/ethernet/qualcomm/qca_7k.h | 1 - .../qualcomm/{qca_framing.c => qca_common.c} | 24 +- .../qualcomm/{qca_framing.h => qca_common.h} | 14 +- drivers/net/ethernet/qualcomm/qca_debug.c | 5 +- drivers/net/ethernet/qualcomm/qca_spi.c | 28 +- drivers/net/ethernet/qualcomm/qca_spi.h | 5 +- drivers/net/ethernet/qualcomm/qca_uart.c | 419 +++++++++++++++++++++ drivers/tty/serdev/core.c | 33 ++ drivers/tty/serdev/serdev-ttyport.c | 49 ++- include/linux/serdev.h | 22 ++ 14 files changed, 634 insertions(+), 50 deletions(-) create mode 100644 Documentation/devicetree/bindings/net/qca-qca7000-uart.txt rename drivers/net/ethernet/qualcomm/{qca_framing.c => qca_common.c} (86%) rename drivers/net/ethernet/qualcomm/{qca_framing.h => qca_common.h} (90%) create mode 100644 drivers/net/ethernet/qualcomm/qca_uart.c -- 2.1.4 -- To unsubscribe from this list: send the line "unsubscribe linux-serial" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
