Subject: [PATCH v3 3/8] dt-bindings: display: xlnx: Add ZynqMP DP subsystem bindings
Date: Mon, 15 Jan 2018 17:57:06 -0800	[thread overview]
Message-ID: <1516067831-11382-3-git-send-email-hyun.kwon@xilinx.com> (raw)
In-Reply-To: <1516067831-11382-1-git-send-email-hyun.kwon-gjFFaj9aHVfQT0dZR+AlfA@public.gmane.org>

This add a dt binding for ZynqMP DP subsystem.

Signed-off-by: Hyun Kwon <hyun.kwon-gjFFaj9aHVfQT0dZR+AlfA@public.gmane.org>

+Xilinx ZynqMP DisplayPort subsystem
+-----------------------------------
+
+Required properties:
+
+- compatible: Must be "xlnx,zynqmp-dpsub-1.7".
+
+- reg: Physical base address and length of the registers set for the device.
+- reg-names: Must be "dp", "blend", "av_buf", and "aud" to map logical register
+  partitions.
+
+- interrupts: Interrupt number.
+- interrupts-parent: phandle for interrupt controller.
+
+- clocks: phandles for axi, audio, non-live video, and live video clocks.
+  axi clock is required. Audio clock is optional. If not present, audio will
+  be disabled. One of non-live or live video clock should be present.
+- clock-names: The identification strings are required. "aclk" for axi clock.
+  "dp_aud_clk" for audio clock. "dp_vtc_pixel_clk_in" for non-live video clock.
+  "dp_live_video_in_clk" for live video clock (clock from programmable logic).
+
+- phys: phandles for phy specifier.
+- phy-names: The identifier strings. "dp-phy" followed by index.
+
+- power-domains: phandle for the corresponding power domain
+
+- ports: There are 2 logical blocks in the IP: display controller and
+  DisplayPort encoder. Each block can be used / connected independently with
+  external device, hence ports for each block are required using DT bindings
+  defined in Documentation/devicetree/bindings/graph.txt. Refer to
+  ./xlnx,display.txt for how topology for entire pipeline is described.
+
+- vid-layer, gfx-layer: Required to represent available layers
+
+Required layer properties
+
+- dmas: phandles for DMA channels as defined in
+  Documentation/devicetree/bindings/dma/dma.txt.
+- dma-names: The identifier strings are required. "graphics0" for graphics
+  layer. "video" followed by index for video layer
+
+Optional child node
+
+- The driver populates any child device node in this node. This can be used,
+  for example, to populate the sound device from the DisplayPort subsystem
+  driver.
+
+Example:
+       zynqmp_dpsub: zynqmp_dpsub@fd4a0000 {
+               compatible = "xlnx,zynqmp-dpsub-1.7";
