[PATCH 0/5] arm64: dts: imx: Add LPSPI alias for I.MX8ULP/8QXP/8QM/8DXL/93

From: Carlos Song <carlos.song@nxp.com>

Now there is no alias for LPSPI on I.MX8ULP/8QXP/8QM/8DXL/93.
So spidevB.C index B will be automatically allocated by kernel
incrementally from zero according to the order of registering
spi controller. In this case, it is hard to determine spidevB.C
is spi interface of device C on which LPSPI bus. It will cause
confusion when operate spi devices in userspace.

For example, in I.MX93, When LPSPI3 and LPSPI5 are enabled
without alais:

:~# ls /dev/spidev*
/dev/spidev0.0  /dev/spidev1.0

After LPSPI alais is applied, fixedly B is the LPSPI index and
C is the spi device index in spidevB.C. They are the pleasant
spidev names. Directly spidev2.0 is the device0 at LPSPI3 bus
and spidev4.0 is the device0 at LPSPI5 bus:

:~# ls /dev/spidev*
/dev/spidev2.0  /dev/spidev4.0
