[PATCH v6 0/4] Add mt8186 dsi compatoble & Convert dsi_dtbinding to .yaml

[PATCH v6 0/4] Add mt8186 dsi compatoble & Convert dsi_dtbinding to .yaml

[Rex-BC Chen]

Changes since v5:
1. Drop #address-cells, #size-cells.
2. Based on chunkuang.hu/linux.git/mediatek-drm-next

Changes since v4:
1. Modify DSI dt-binding.
2. Add support for MT8186 DSI in mtk_drm_drv.c.

Changes since v3:
1. Add dsi port property.
2. Fix some formatting.

Changes since v2:
1. Added #address-cells, #size-cells two properties.
2. Fix some formatting issues.

Changes since v1:
1. Delete the mediatek,dsi.txt & Add the mediatek,dsi.yaml.
2. Ignore the Move the getting bridge node function patch for V1.

-Mediatek DSI Device
-===================
-
-The Mediatek DSI function block is a sink of the display subsystem and can
-drive up to 4-lane MIPI DSI output. Two DSIs can be synchronized for dual-
-channel output.
-
-Required properties:
-- compatible: "mediatek,<chip>-dsi"
-- the supported chips are mt2701, mt7623, mt8167, mt8173 and mt8183.
-- reg: Physical base address and length of the controller's registers
-- interrupts: The interrupt signal from the function block.
-- clocks: device clocks
-  See Documentation/devicetree/bindings/clock/clock-bindings.txt for details.
-- clock-names: must contain "engine", "digital", and "hs"
-- phys: phandle link to the MIPI D-PHY controller.
-- phy-names: must contain "dphy"
-- port: Output port node with endpoint definitions as described in
-  Documentation/devicetree/bindings/graph.txt. This port should be connected
-  to the input port of an attached DSI panel or DSI-to-eDP encoder chip.
-
-Optional properties:
-- resets: list of phandle + reset specifier pair, as described in [1].
-
-[1] Documentation/devicetree/bindings/reset/reset.txt
-
-MIPI TX Configuration Module
-============================
-
-See phy/mediatek,dsi-phy.yaml
-
-Example:
-
-mipi_tx0: mipi-dphy@10215000 {

-	clocks = <&clk26m>;
-	clock-output-names = "mipi_tx0_pll";
-	#clock-cells = <0>;
-	#phy-cells = <0>;
-	drive-strength-microamp = <4600>;
-	nvmem-cells= <&mipi_tx_calibration>;

You can check status for yourself by looking at PW[1] where you will
see the review queue is currently ~120 patches and goes back to 5/3.
If it is in the queue, I will get to it.
