ZynqMP serial input output unit (SIOU) is a high-speed serial interface block that acts as a phy interface for the PCIe, USB 3.0, DisplayPort, SATA, and Ethernet controllers. These controllers use any one among the available four multigigabit transceivers for high-speed communication with their link partners outside the SOC ZynqMP SIOU supports multiple protocols working at different reference clock frequencies to operate simultaneously. Each of the four lanes will be having a dedicated PLL associated which generates the desired frequency required by the protocol configured based on the reference clock input given. Using this driver, user can select the desired reference clock frequency for each of lane 0, lane 1, lane 2, and lane 3 respectively. Each lane can be programmed to have its own reference clock or can share reference clock from its neighboring lane, this is called as "Clock Sharing". This driver supports the above mentioned clock sharing aswell. These set of patches add support SIOU support by adding zynqmp-phy driver to linux. This patch series is based on the initial work done by "Subbaraya Sundeep" https://lore.kernel.org/patchwork/patch/635317/ Changes in v5: 1. No functional changes. Added missing Author name Changes in v4: 1. Fixed the changes in phy-zynqmp.txt as suggested by "Rob Herring" 2. Moved the dt-bindings patch from 2nd to 1st Changes in v3: 1. Corrected the Documentation as suggested by "Vivek Gautam" Changes in v2: 1. Fixed the compilation error when compiled phy-zynqmp.c as a module 2. Added CONFIG_PM macro in phy-zynqmp.c driver Anurag Kumar Vulisha (2): phy: zynqmp: Add dt bindings for ZynqMP phy phy: zynqmp: Add phy driver for xilinx zynqmp phy core .../devicetree/bindings/phy/phy-zynqmp.txt | 109 ++ drivers/phy/Kconfig | 8 + drivers/phy/Makefile | 1 + drivers/phy/phy-zynqmp.c | 1582 ++++++++++++++++++++ include/dt-bindings/phy/phy.h | 2 + include/linux/phy/phy-zynqmp.h | 52 + 6 files changed, 1754 insertions(+) create mode 100644 Documentation/devicetree/bindings/phy/phy-zynqmp.txt create mode 100644 drivers/phy/phy-zynqmp.c create mode 100644 include/linux/phy/phy-zynqmp.h -- 2.1.1
