LM3530SW-LINUX: Kernel start up error in Linux driver

Part Number: LM3530SW-LINUX
Other Parts Discussed in Thread: LM3530,

Hello team,

My customer has a question about kernel start up error in Linux driver of the LM3530 into Linux4.14.98.

My predecessor asked the same question in the link below, but it's currently locked without any feedbacks.

LM3530SW-LINUX: Linux driver had an error when kernel start up | E2E Forum(

The device driver define in Kernel configuration, and describe the LM3530 in device tree as below. But error occurred in lm3530_probe when kernel start up like below.

Is the description of device tree wrong?

If there is an example of the description in the device tree, we would like to see it.

Could you please check it and give me your advise?


lm3530: lm3530-led@38 {

compatible = "ti,lm3530-led";

reg = <0x38>;



Error: lm3530-led 2-0038: platform data required

They have two system with Linux4.14 and Linux4.19, customer would like to workaround for both.

It would be greatly appreciated if you could find any update about it.

Best regards,

Ryotaro Fukui
