Subject: [PATCH RFC v9 10/20] Documentation: dt-bindings: Add bindings for Synopsys DW MIPI DSI DRM bridge driver
Date: Thu, 12 Feb 2015 14:01:33 +0800 [thread overview]
Message-ID: <1423720903-24806-11-git-send-email-Ying.Liu@freescale.com> (raw)
In-Reply-To: <1423720903-24806-1-git-send-email-Ying.Liu@freescale.com>
This patch adds device tree bindings for Synopsys DesignWare MIPI DSI
host controller DRM bridge driver.
Signed-off-by: Liu Ying <Ying.Liu@freescale.com>
---
v8->v9:
* Rebase onto the imx-drm/next branch of Philipp Zabel's open git repository.
* To address Philipp's comment, mention that a common compatible string
"snps,dw-mipi-dsi" should be appended for all SoCs.
* To address Philipp's comment, add a new required clock pclk and clean up
clock-names.
v7->v8:
* None.
v6->v7:
* None.
v5->v6:
* Add the #address-cells and #size-cells properties in the example 'ports'
node.
* Remove the useless input-port properties from the example port@0 and port@1
nodes.
v4->v5:
* None.
v3->v4:
* Newly introduced in v4. This is separated from the relevant driver patch
in v3 to address Stefan Wahren's comment.

+Device-Tree bindings for Synopsys DesignWare MIPI DSI host controller
+
+The controller is a digital core that implements all protocol functions
+defined in the MIPI DSI specification, providing an interface between
+the system and the MIPI DPHY, and allowing communication with a MIPI DSI
+compliant display.
+
+Required properties:
+ - #address-cells: Should be <1>.
+ - #size-cells: Should be <0>.
+ - compatible: The first compatible string should be "fsl,imx6q-mipi-dsi"
+ for i.MX6q/sdl SoCs. For other SoCs, please refer to their specific
+ device tree binding documentations. A common compatible string
+ "snps,dw-mipi-dsi" should be appended for all SoCs.
+ - reg: Represent the physical address range of the controller.
+ - interrupts: Represent the controller's interrupt to the CPU(s).
+ - clocks, clock-names: Phandles to the controller's pll reference
+ clock(ref), configuration clock(cfg) and APB clock(pclk), as
+ described in [1].
+
+For more required properties, please refer to relevant device tree binding
+documentations which describe the controller embedded in specific SoCs.
+
+Required sub-nodes:
+ - A node to represent a DSI peripheral as described in [2].
+
+For more required sub-nodes, please refer to relevant device tree binding
+documentations which describe the controller embedded in specific SoCs.
