Re: [PATCH v4 1/1] arm64: dts: freescale: add pixpaper display overlay for i.MX93 FRDM

arch/arm64/boot/dts/freescale/imx93-11x11-frdm-pixpaper.dtb: display@0 (mayqueen,pixpaper): spi-max-frequency: 5000000 is greater than the maximum of 1000000
        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.

Thanks,
Wig
