        from schema $id: http://devicetree.org/schemas/display/mayqueen,pixpaper.yaml

Does 1000000 work for spi-max-frequency? or need update binding doc?

Both 1MHz and 5MHz work on i.MX93. I chose 5MHz for better refresh
performance, which is within the LPSPI3 controller's capabilities.
The 1MHz limit in the binding is a conservative generic value I think.

Okay, let change to 1Mhz first. we will update it after updated binding
doc.

Hi Frank,
I've sent v5 with 1MHz as you suggested:

Thanks for your help,
