Question
Is there a way to use the B-LCDAD-HDMI adapter (bridge chip ADV7533) instead of the default panel DSI on the STM32MP157a-ev1 board?
Hi,
I tried to update the DTS to make use of the adapter but unfortunately without success. These are the change I made:
hdmi-out {
compatible = "hdmi-connector";
type = "a";
port {
hdmi_con: endpoint {
remote-endpoint = <&adv7533_out>;
};
};
};
&dsi {
phy-dsi-supply = <®18>;
#address-cells = <1>;
#size-cells = <0>;
status = "okay";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
dsi_in: endpoint {
remote-endpoint = <<dc_ep0_out>;
};
};
port@1 {
reg = <1>;
dsi_out: endpoint {
remote-endpoint = <&adv7533_in>;
};
};
};
};
&i2c2 {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&i2c2_pins_a>;
pinctrl-1 = <&i2c2_pins_sleep_a>;
i2c-scl-rising-time-ns = <185>;
i2c-scl-falling-time-ns = <20>;
status = "okay";
/delete-property/dmas;
/delete-property/dma-names;
hdmi-transmitter@3d {
compatible = "adi,adv7533";
reg = <0x3d>; // (3d = 7A>>1)
a2vdd-supply = <&v1v8>;
v3p3-supply = <&v3v3>;
v1p2-supply = <&v1v8>;
avdd-supply = <&v1v8>;
dvdd-supply = <&v1v8>;
pvdd-supply = <&v1v8>;
dvdd-3v-supply = <&v3v3>;
adi,dsi-lanes = <2>;
adi,disable-timing-generator = <1>;
status = "okay";
ports {
#address-cells = <1>;
#size-cells = <0>;
port@0 {
reg = <0>;
adv7533_in: endpoint {
remote-endpoint = <&dsi_out>;
};
};
port@1 {
reg = <1>;
adv7533_out: endpoint {
remote-endpoint = <&hdmi_con>;
};
};
};
};thanks in advance for your help.
Luca.
