> Subject: [PATCH 1/1] arm64: dts: imx93-9x9-qsb: add I3C overlay file
> 
> Add an overlay file to enable I3C support on the i.MX93, replacing I2C1
> with I3C. I3C is compatible with I2C, but it has not yet been enabled in
> arm64's defconfig. This overlay allows users to conveniently utilize I3C
> on the imx93-9x9-qsb platform until I3C and its driver become more
> mature and ready for full switch to I3C.
