LM3530SW-LINUX: Linux driver had an error when kernel start up

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


My customer is implementing a Linux driver of the LM3530 into Linux4.14.98.

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.

here is the description of device tree and error.

Is the description of device tree wrong?

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.

Best regards,
