LED driver on armstoneA9r3

RSchubert · Aug 29th 2024

Dear Support-Team,

In the kernel log we have following error:

Code

It's from static int pca963x_write_reg(struct pca963x *pca963x, u8 reg, u8 value) inside file leds-pca963x-fus.c.

We just want to check if this can be ignored or not before releasing the new kernel to our devices.

Any idea?

Hardware: armstoneA9r3 Rev 2.00

Software: Buildroot Release fsimx6-B2024.04

Thanks.

RS

Hello,

this comes from the pca9632 GPIO-Expander on the ADP-AStone2EDT2-LCD Display adapter.

If you are not using this, you should be ok to set

status = "disabled";

However, you will also have to disable the nodes that reference it

It should also be OK to ignore it, but it would be cleaner to just disable these unused nodes.
