Add initial support for slimport anx7625
Subsystems (4)
v10 cover Add initial support for slimport anx7625
Hi all,
The following series add support for the Slimport ANX7625 transmitter, a ultra-low power Full-HD 4K MIPI to DP transmitter designed for portable device.
This is the v10 version, any mistakes, please let me know, I will fix it in the next series.
Change history:
v10: Fix comments from Rob Herring, Daniel.
- Fix dt_binding_check warning.
- Update description.
v9: Fix comments from Sam, Nicolas, Daniel
- Remove extcon interface.
- Remove DPI support.
- Fix dt_binding_check complains.
- Code clean up and update description.
v8: Fix comments from Nicolas.
- Fix several coding format.
- Update description.
v7:
- Fix critical timing(eg:odd hfp/hbp) in "mode_fixup" interface, enhance MIPI RX tolerance by setting register MIPI_DIGITAL_ADJ_1 to 0x3D.

PATCH v10 1/2 dt-bindings: drm/bridge: anx7625: MIPI to DP transmitter binding
The ANX7625 is an ultra-low power 4K Mobile HD Transmitter designed for portable device. It converts MIPI to DisplayPort 1.3 4K.
You can add support to your board with binding.
Example:
anx7625_bridge: encoder@58 {
compatible = "analogix,anx7625";
reg = <0x58>;
status = "okay";
enable-gpios = <&pio 45 GPIO_ACTIVE_HIGH>;
reset-gpios = <&pio 73 GPIO_ACTIVE_HIGH>;
ports {
#address-cells = <1>;
#size-cells = <0>;
mipi2dp_bridge_in: port@0 {
reg = <0>;
anx7625_in: endpoint {
remote-endpoint = <&mipi_dsi>;
};
};
mipi2dp_bridge_out: port@1 {
reg = <1>;
anx7625_out: endpoint {
remote-endpoint = <&panel_in>;
};
};

PATCH v10 2/2 drm/bridge: anx7625: Add anx7625 MIPI DSI/DPI to DP bridge driver
In reply to Xin JiThe ANX7625 is an ultra-low power 4K Mobile HD Transmitter designed for portable device. It converts MIPI DSI/DPI to DisplayPort 1.3 4K.
The ANX7625 can support both USB Type-C PD feature and MIPI DSI/DPI to DP feature. This driver only enabled MIPI DSI/DPI to DP feature.
