The zynqmp power domain driver communicates the usage requirements for logical power domains / devices to the platform FW. FW is responsible for choosing appropriate power states, taking Linux' usage information into account. v4: - Added reviewed tag for dt bindings - Remove local device list for each domain and use list maintained in core genpd structure - Remove hardcoded pd-id to node ID mapping. Instead use argument passed in peripheral node as node ID. Firmware would validate node ID when APIs requested from genpd ops. v3: - Changed binding to have FW node as a power controller as suggested by Rob - Updated FW driver to register it as mfd child devices from firmware probe - Move bindings location as suggested v2: - Rebased on top of latest firmware driver patch series - Updated driver name from zynqmp-genpd to zynqmp-power-controller - Updated device tree bindings to move power controller node under firmware node Jolly Shah (1): drivers: soc: xilinx: Add ZynqMP power domain driver Rajan Vaja (2): dt-bindings: power: Add ZynqMP power domain bindings firmware: xilinx: Add APIs to control node status/power .../bindings/power/xlnx,zynqmp-genpd.txt | 34 +++ drivers/firmware/xilinx/Kconfig | 1 + drivers/firmware/xilinx/zynqmp.c | 73 +++++ drivers/soc/xilinx/Kconfig | 9 + drivers/soc/xilinx/Makefile | 1 + drivers/soc/xilinx/zynqmp_pm_domains.c | 321 +++++++++++++++++++++ include/dt-bindings/power/xlnx-zynqmp-power.h | 39 +++ include/linux/firmware/xlnx-zynqmp.h | 26 ++ 8 files changed, 504 insertions(+) create mode 100644 Documentation/devicetree/bindings/power/xlnx,zynqmp-genpd.txt create mode 100644 drivers/soc/xilinx/zynqmp_pm_domains.c create mode 100644 include/dt-bindings/power/xlnx-zynqmp-power.h -- 2.7.4
