This patch series adds support for the Qualcomm QCA7000 Homeplug GreenPHY. The QCA7000 is serial-to-powerline bridge with two interfaces: UART and SPI. These patches handles only the last one, with an Ethernet over SPI protocol driver. This driver based on the Qualcomm code [1], but contains a lot of changes since last year: * devicetree support * DebugFS support * ethtool support * better error handling * performance improvements * code cleanup * some bugfixes The code has been tested only on Freescale i.MX28 boards, but should work on other platforms. [1] - https://github.com/IoE/qca7000 Changes in V3: - Use ether_addr_copy instead of memcpy - Remove qcaspi_set_mac_address - Improve DT parsing - replace OF_GPIO dependancy with OF - fix compile error caused by SET_ETHTOOL_OPS - fix possible endless loop when spi read fails - fix DT documentation - fix coding style - fix sparse warnings Changes in V2: - replace in DT the SPI intr GPIO with pure interrupt - make legacy mode a boolean DT property and remove it as module parameter - make burst length a module parameter instead of DT property - make pluggable a module parameter instead of DT property - improve DT documentation - replace debugFS register dump with ethtool function - replace debugFS stats with ethtool function - implement function to get ring parameter via ethtool - implement function to set TX ring count via ethtool - fix TX ring state in debugFS - optimize tx ring flush - add byte limit for TX ring to avoid bufferbloat - fix TX queue full and write buffer miss counter - fix SPI clk speed module parameter - fix possible packet loss - fix possible race during transmit Stefan Wahren (2): Documentation: add Device tree bindings for QCA7000 net: qualcomm: new Ethernet over SPI driver for QCA7000 .../devicetree/bindings/net/qca-qca7000-spi.txt | 47 + drivers/net/ethernet/Kconfig | 1 + drivers/net/ethernet/Makefile | 1 + drivers/net/ethernet/qualcomm/Kconfig | 30 + drivers/net/ethernet/qualcomm/Makefile | 6 + drivers/net/ethernet/qualcomm/qca_7k.c | 149 +++ drivers/net/ethernet/qualcomm/qca_7k.h | 72 ++ drivers/net/ethernet/qualcomm/qca_debug.c | 311 ++++++ drivers/net/ethernet/qualcomm/qca_debug.h | 34 + drivers/net/ethernet/qualcomm/qca_framing.c | 156 +++ drivers/net/ethernet/qualcomm/qca_framing.h | 134 +++ drivers/net/ethernet/qualcomm/qca_spi.c | 993 ++++++++++++++++++++ drivers/net/ethernet/qualcomm/qca_spi.h | 114 +++ 13 files changed, 2048 insertions(+) create mode 100644 Documentation/devicetree/bindings/net/qca-qca7000-spi.txt create mode 100644 drivers/net/ethernet/qualcomm/Kconfig create mode 100644 drivers/net/ethernet/qualcomm/Makefile create mode 100644 drivers/net/ethernet/qualcomm/qca_7k.c create mode 100644 drivers/net/ethernet/qualcomm/qca_7k.h create mode 100644 drivers/net/ethernet/qualcomm/qca_debug.c create mode 100644 drivers/net/ethernet/qualcomm/qca_debug.h create mode 100644 drivers/net/ethernet/qualcomm/qca_framing.c create mode 100644 drivers/net/ethernet/qualcomm/qca_framing.h create mode 100644 drivers/net/ethernet/qualcomm/qca_spi.c create mode 100644 drivers/net/ethernet/qualcomm/qca_spi.h -- 1.7.9.5 -- To unsubscribe from this list: send the line "unsubscribe devicetree" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
