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. This patch series is based on top of Xilinx firmware patch set: https://patchwork.kernel.org/cover/10555405/ 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 (3): dt-bindings: power: Add ZynqMP power domain bindings firmware: xilinx: Add APIs to control node status/power firmware: xilinx: Add node IDs for zynqmp firmware .../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 | 2 + drivers/soc/xilinx/zynqmp_pm_domains.c | 403 +++++++++++++++++++++ include/dt-bindings/power/xlnx-zynqmp-power.h | 39 ++ include/linux/firmware/xlnx-zynqmp.h | 98 +++++ 8 files changed, 659 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
