Can we use multiple instances of the apa102 driver?

[fgervais]

I'm trying to use 3 spi buses with one apa102 strip each.

I'm casually adding one instance of the apa102 device per spi buses in the device tree but it fails when I have more than one.

Is there a limitation in the number instance of the apa102 driver?

It seems that there is a limitation so I proposed this change #58148.
