+i.MX specific Device-Tree bindings for Synopsys DesignWare MIPI DSI host controller
+
+MIPI DSI host controller
+========================
+
+The MIPI DSI host controller is a Synopsys DesignWare IP.
+The common device tree documentation for this controller can be found
+at [1].
+
+Required properties:
+ - #address-cells: Should be <1>.
+ - #size-cells: Should be <0>.
+ - compatible: The compatible string should be "fsl,imx6q-mipi-dsi"
+ for i.MX6q/sdl SoCs.
+ - reg: Physical base address of the controller and length of memory
+ mapped region.
+ - interrupts: The controller's interrupt number to the CPU(s).
+ - gpr: Should be <&gpr>.
+ The phandle points to the iomuxc-gpr region containing the
+ multiplexer control register for the controller.
+ - clocks, clock-names: Phandles to the controller pllref and core_cfg clocks,
+ as described in [2] and [3].
+
+Required sub-nodes:
+ - ports: This node may contain up to four port nodes with endpoint
+ definitions as defined in [4], corresponding to the four inputs to
+ the controller multiplexer.
+ - A node to represent a DSI peripheral as described in [5].

This patch adds device tree bindings for i.MX specific Synopsys DW MIPI DSI driver. Signed-off-by: Liu Ying <Ying.Liu@freescale.com> --- v6->v7: * None. v5->v6: * Add the #address-cells and #size-cells properties in the example 'ports' node. * Remove the useless pllref_gate clock from the required clocks, clock-names property. 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. .../devicetree/bindings/drm/imx/mipi_dsi.txt | 78 ++++++++++++++++++++++ 1 file changed, 78 insertions(+) create mode 100644 Documentation/devicetree/bindings/drm/imx/mipi_dsi.txt
