IPU device tree configuration for imx6ul

[davidzhou]

Hi,

I have an imx6ul development board.

I can not find any patch that adds IPU driver into the device tree.
    ipu1: ipu@02400000 {
compatible = "fsl,imx6q-ipu";
...
}

Can you help me make or find a patch  file that is "fsl, imx6ul-ipu" compatible?

Thank you,

David

Hi Yuri,

Thank you for reply.

But I found this information:

i.MX Linux® Reference Manual

Document Number: IMXLXRM

Rev. 0, 03/2016

Chapter 6. IPU

IPU The Image Processing Unit (IPU) is designed to

support video and graphics processing functions and to

interface with video/still image sensors and displays.

The IPU driver is a self-contained driver module in the

Linux kernel. It contains a custom kernel-level API to

manipulate logical channels. A logical channel

represents a complete IPU processing flow. The IPU

driver includes a frame buffer driver, a V4L2 device

driver, and low-level IPU drivers.

Drivers

i.MX 6Quad,

i.MX 6Dual,

i.MX 6DualLite,

i.MX 6Solo,

i.MX 6UltraLite, //IT IS LISTED HERE

i.MX 7Dual

Hello,

  Looks like this is misprint in Linux documentation, that i.MX6UL and i.MX7 have IPU.
Use i.MX6UL and i.MX7 Datasheets (Hardware specs) and RMs for correct information,

they are equipped with PXP (instead of IPU).

Regards,

Yuri.
