Beagleboard-xM Camera LI-5M03 (MT9P031) Support With Device Tree Tested

[raj]

Hello,

I've verified beagleboard-xM camera LI-5M03 (mt9p031) with device tree
on Linux 4.2.0-rc5 with the help of Laurent and Sakari.

If anybody interested, please go through link for more details

Hi Alaganraj,

I've used your device tree on the BBxm with kernel 5.0.19 but I supsect that only 9 bits are captured instead of 12.

The doubt arise from the fact that even with Test Pattern I cannot see white but the highest value is 511 which is a dark gray.

I'm missing something ? Here below the device tree:

+&i2c2 {

+ clock-frequency = <100000>;

+

+ mt9p031@48 {

+ compatible = "aptina,mt9p031";

+ reg = <0x48>;

+

+ clocks = <&isp 0>;

+ reset-gpios = <&gpio4 2 GPIO_ACTIVE_LOW>;

+

+ vaa-supply = <&hsusb2_power>;

+ vdd-supply = <&vaux3>;

+ vdd_io-supply = <&vaux4>;

+

+ port {

+ mt9p031_out: endpoint {

+ input-clock-frequency = <21000000>;

+ pixel-clock-frequency = <48000000>;

+ remote-endpoint = <&ccdc_ep>;

+ };

+ };

+ };

+};

+

+&isp {

+ #address-cells = <1>;

+ #size-cells = <0>;

+

+ ports {

+ port@0 {

+ reg = <0>;

+ ccdc_ep: endpoint {

+ remote-endpoint = <&mt9p031_out>;

+ bus-width = <12>;

+ hsync-active = <1>;

+ vsync-active = <1>;

+ pclk-sample = <0>;

+ };

+ };

+ };

+};

Thank you in advance for any hints.
