The Cadence Sierra PHY supports a number of different protocols. This series adds a driver with support for USB3 and PCIe modes. Only one clock frequency is currently supported, so the value of clock provided in device tree is ignored. Changes since v2: * Rebased on 4.20-rc1 * Renamed cdns-sierra-phy.txt to phy-cadence-sierra.txt, to match DP PHY * Renamed phy-cdns-sierra.c to phy-cadence-sierra.c, to match DP PHY * Removed blank line at end of devicetree bindings description Changes since v1: * Moved subnode resets into each subnode in devicetree bindings * Modified driver to put subnode resets on exit * Changed driver filename to phy-cdns-sierra.c Changes since RFC v2: * Devicetree bindings modified as suggested by Rob Herring. * Tidy up and correction of return paths in probe function. Changes since RFC v1: * Each group of lanes is now treated as a subnode, and a generic PHY device is created for each group. * General cleanup based on comments * A reset is now required for each subnode. The complete PHY block is taken out of reset at initial probe, and remains out of reset. * Added a binding to allow for hardware configuration of PHY registers Alan Douglas (2): dt-bindings: phy: Document cadence Sierra PHY bindings phy: cadence: Add driver for Sierra PHY .../devicetree/bindings/phy/phy-cadence-sierra.txt | 67 ++++ drivers/phy/cadence/Kconfig | 9 +- drivers/phy/cadence/Makefile | 1 + drivers/phy/cadence/phy-cadence-sierra.c | 395 +++++++++++++++++++++ 4 files changed, 471 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/phy/phy-cadence-sierra.txt create mode 100644 drivers/phy/cadence/phy-cadence-sierra.c -- 1.9.0
