FPGA on LX2160AQDS/LX2160ARDB connected on I2C bus, so add qixis driver which is basically an i2c client driver to control FPGA.
This driver is essential to control MDIO mux multiplexing. This driver is dependent on below patches: https://www.mail-archive.com/netdev@vger.kernel.org/msg281274.html V1 of this series: https://patchwork.kernel.org/cover/10627297/ Cc: Varun Sethi <v.se...@nxp.com> Pankaj Bansal (2): dt-bindings: soc: fsl: Document Qixis FPGA usage fsl: add i2c controlled qixis driver .../bindings/soc/fsl/qixis_ctrl.txt | 33 +++++ drivers/soc/fsl/Kconfig | 8 ++ drivers/soc/fsl/Makefile | 1 + drivers/soc/fsl/qixis_ctrl.c | 121 ++++++++++++++++++ 4 files changed, 163 insertions(+) create mode 100644 Documentation/devicetree/bindings/soc/fsl/qixis_ctrl.txt create mode 100644 drivers/soc/fsl/qixis_ctrl.c -- 2.17.1
