GPIO modepin driver set and get the value and status of the PS_MODE pin, based on device-tree pin configuration. These four-bits boot-mode pins are dedicated configurable as input/output. After the stabilization of the system,these mode pins are sampled. To access GPIO pins, added Xilinx ZynqMP firmware MDIO API support to set and get PS_MODE pins value and status. These APIs are interface APIs, between the mode pin controller driver and low-level API. --- Changes in v2: - Added Xilinx ZynqMP firmware MMIO API support to set and get pin value and status. - DT Documentation- Addressed review comments: Update commit message - Modepin driver- Addressed review comments: - Update APIs - Removed unwanted variables - Handle return path for probe function Review Comments: https://lore.kernel.org/linux-arm-kernel/20210624205055.GA1961487@robh.at.kernel.org/T/#u --- Piyush Mehta (3): firmware: zynqmp: Add MMIO read and write support for PS_MODE pin dt-bindings: gpio: zynqmp: Add binding documentation for modepin gpio: modepin: Add driver support for modepin GPIO controller .../bindings/gpio/xlnx,zynqmp-gpio-modepin.yaml | 41 ++++++ drivers/firmware/xilinx/zynqmp.c | 46 ++++++ drivers/gpio/Kconfig | 12 ++ drivers/gpio/Makefile | 1 + drivers/gpio/gpio-zynqmp-modepin.c | 158 +++++++++++++++++++++ include/linux/firmware/xlnx-zynqmp.h | 14 ++ 6 files changed, 272 insertions(+) create mode 100644 Documentation/devicetree/bindings/gpio/xlnx,zynqmp-gpio-modepin.yaml create mode 100644 drivers/gpio/gpio-zynqmp-modepin.c -- 2.7.4
