This patch series adds support for the TI/National Semiconductor LP5812
4x3 matrix RGB LED driver. The driver supports features such as autonomous
animation and time-cross-multiplexing (TCM) for dynamic LED effects.

Apologies for the delayed reply.

I’ve updated the ABI document based on your previous comments.
Regarding the binding, I’ve removed redundant descriptions and fixed the indentation as you pointed out.

I’ll make sure to describe the changes more clearly in the next patch submission.

Best regards,
Nam Tran
