Dear NXP
I have IMX7D custom model and use with linux kernel version 5.4.47.
When I try to upgrade to version 5.10.72, I found MTD SPI flask memory doesn't.work
In linux version 5.4.47
root@IMX7D:~$ ls -l /dev/mtd*

dmesg
root@IMX7D:~$ dmesg | grep spi

}; This work on 5.4.47 but in 5.10.72 it not found any SPI device and dmesg | grep spi is return empty message
When I compile the kernel 5.10.72 I found warning mesage
Kernel: arch/arm/boot/zImage is ready
DTC arch/arm/boot/dts/imx7d-custom-som-imx7.dtb
arch/arm/boot/dts/imx7d-custom-som-imx7.dts:258.28-281.11: Warning (spi_bus_reg): /soc/bus@30800000/spba-bus@30800000/spi@30820000/m25px16@0: SPI bus unit address format error, expected "1"
Do you have some suggest for me?
