From c0178b8e24b2b1eed8ebfe5b155a36304d42a137 Mon Sep 17 00:00:00 2001 From: Shubhrajyoti Datta Date: Wed, 17 Jun 2020 17:07:23 +0530 Subject: [PATCH] dt-bindings: gpio: Add pmc gpio node to gpio-zynq Add the pmc gpio node to the device tree. 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 Signed-off-by: Michal Simek Signed-off-by: Bartosz Golaszewski --- Documentation/devicetree/bindings/gpio/gpio-zynq.txt | 1 + 1 file changed, 1 insertion(+) diff --git a/Documentation/devicetree/bindings/gpio/gpio-zynq.txt b/Documentation/devicetree/bindings/gpio/gpio-zynq.txt index 4806d846c0fc..f693e82b4c0f 100644 --- a/Documentation/devicetree/bindings/gpio/gpio-zynq.txt +++ b/Documentation/devicetree/bindings/gpio/gpio-zynq.txt @@ -8,6 +8,7 @@ Required properties: parameters (unused) - compatible : Should be "xlnx,zynq-gpio-1.0" or "xlnx,zynqmp-gpio-1.0" or "xlnx,versal-gpio-1.0 + or "xlnx,pmc-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
