IMX6Q dual IPU problem

liweihua — Mon, 11 Dec 2017 12:14:02 GMT

I have heard IMX6Q has two IPUs Compared with IMX6DL having only one.

Then how to config to use both the two IPU?

My configration of device tree now is:

arch/arm/boot/dts/imx6q.dts:

&ldb {
lvds-channel@0 {
crtc = "ipu2-di0";
};

lvds-channel@1 {
crtc = "ipu2-di1";
};
};

arch/arm/boot/dts/imx6q.dtsi:

lcd@0 {
  compatible = "fsl,lcd";
  ipu_id = <0>;
  disp_id = <0>;
  default_ifmt = "RGB24";
  pinctrl-names = "default";
  pinctrl-0 = <&pinctrl_ipu1>;
  status = "okay";
    };

Please modify it to use both the two IPU.

Thanks & Best Regards

Levi

Hi Levi

for ipu usage one can look at p.17 presentation

A Deep Dive into Image Processing for i.MX 6 Series Applications Processors

Muxing performed by IOMUXC_GPR registers described in IOMUX Chapter of i.MX6Q Reference Manual.

For configuring various configurations may be useful to look at BD boards, as they have many lcd options

Configuring i.MX6 boards for different screens - Boundary Devices

linux-imx6/arch/arm/boot/dts at boundary-imx_4.1.15_1.0.0_ga · boundarydevices/linux-imx6 · GitHub

in dts file one can pay attention to entries like "ipu2-di0".

Best regards
