From: Shubhrajyoti Datta <shubhrajyoti.da...@xilinx.com> Add binding for Versal binding.
Versal devices are the industry's first adaptive compute acceleration platforms. https://www.xilinx.com/support/documentation/data_sheets/ds950-versal-overview.pdf On the Versal platform, we are using two customized GPIO controllers(IP) which were used in Zynq/ZynqMp platform. One of them present in the Platform Management Controller(PMC) block and other in Processing System(PS) block. In PMC_GPIO only Bank0,1,3 & 4 are enabled and in PS_GPIO only Bank 0 & 3 are enabled. You can find more details of GPIO IP in ZynqMP TRM General Purpose I/O(Chapter-27). https://www.xilinx.com/support/documentation/user_guides/ug1085-zynq-ultrascale-trm.pdf Signed-off-by: Shubhrajyoti Datta <shubhrajyoti.da...@xilinx.com> Signed-off-by: Michal Simek <michal.si...@xilinx.com> --- Documentation/devicetree/bindings/gpio/gpio-zynq.txt | 3 ++- 1 file changed, 2 insertions(+), 1 deletion(-) diff --git a/Documentation/devicetree/bindings/gpio/gpio-zynq.txt b/Documentation/devicetree/bindings/gpio/gpio-zynq.txt index 4fa4eb5507cd..4806d846c0fc 100644 --- a/Documentation/devicetree/bindings/gpio/gpio-zynq.txt +++ b/Documentation/devicetree/bindings/gpio/gpio-zynq.txt @@ -6,7 +6,8 @@ Required properties: - First cell is the GPIO line number - Second cell is used to specify optional parameters (unused) -- compatible : Should be "xlnx,zynq-gpio-1.0" or "xlnx,zynqmp-gpio-1.0" +- compatible : Should be "xlnx,zynq-gpio-1.0" or + "xlnx,zynqmp-gpio-1.0" or "xlnx,versal-gpio-1.0 - clocks : Clock specifier (see clock bindings for details) - gpio-controller : Marks the device node as a GPIO controller. - interrupts : Interrupt specifier (see interrupt bindings for -- 2.7.4
