| Message-ID | <qMYxz-2pY-3@gated-at.bofh.it> |
Hi all, This is another version of the patch set to introduce the anx7814 transmitter. Any comments are welcome. The following series add initial support for the Slimport ANX7814 transmitter, a ultra-low power Full-HD (1080p60) transmitter designed for portable device. The driver was originally created and based from the work of Junhua Xia from Analogix. This driver is a refactor of the original driver and fixes different coding style lines, and different errors/warnings reported by checkpatch. Also there were things that I noticed that we need to change like: - Convert the numbered GPIO API to the new descriptor based GPIO API. - Review the DT binding - Add missing MODULE_DEVICE_TABLE(of, ...); - Fix Makefiles and Kconfig to build conditionally. - Use SIMPLE_DEV_PM_OPS() instead of the deprecated i2c .suspend and .resume callbacks. - Move to use managed device resources. - Remove dead/unused code. - And others ...

| In reply to | #1300394 |
The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter
designed for portable devices.
You can add support to your board with current binding.
Example:
anx7814: anx7814@38 {
compatible = "analogix,anx7814";
reg = <0x38>;
interrupt-parent = <&gpio0>
interrupts = <1 IRQ_TYPE_LEVEL_HIGH>;
pd-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
reset-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;
v10-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>;
port {
anx7814_in: endpoint {
remote-endpoint = <&hdmi0_out>;
};
};
};

---
Changes since last version (requested by Rob Herring)
- Use just "port" instead of ports.
- Add Acked-by: Rob Herring <robh@kernel.org>
Changes since v5:
- Specify how many ports and how many endpoints for each port
- Simplify to just port (dropping ports)
- For cable det use an interrupt instead (to a gpio controller)

+Analogix ANX7814 SlimPort (Full-HD Transmitter)
+-----------------------------------------------
+
+The ANX7814 is an ultra-low power Full-HD (1080p60) SlimPort transmitter
+designed for portable devices.
+
+Required properties:
+
+ - compatible : "analogix,anx7814"
+ - reg : I2C address of the device
+ - interrupt-parent : Should be the phandle of the interrupt controller
+ that services interrupts for this device
+ - interrupts : Should contain the cable detection interrupt
+ - pd-gpios : Which GPIO to use for power down
+ - reset-gpios : Which GPIO to use for reset
+
+Optional properties:
+
+ - v10-gpios : Which GPIO to use for V10 control.
+ - Video port for HDMI output, using the DT bindings defined in [1].
+
+[1]: Documentation/devicetree/bindings/media/video-interfaces.txt

+Example:
+
+ anx7814: anx7814@38 {
+ compatible = "analogix,anx7814";
+ reg = <0x38>;
+ interrupt-parent = <&gpio0>
+ interrupts = <1 IRQ_TYPE_LEVEL_HIGH>;
+ pd-gpios = <&gpio0 2 GPIO_ACTIVE_HIGH>;
+ reset-gpios = <&gpio0 3 GPIO_ACTIVE_HIGH>;
+ v10-gpios = <&gpio0 4 GPIO_ACTIVE_HIGH>;
+ port {
+ anx7814_in: endpoint {
+ remote-endpoint = <&hdmi0_out>;
+ };
+ };
