IMX93 RS485 Multidrop support

[EmbeddedFox]

Hi,

We are using the IMX93 in one of our projects that require RS485 with multidrop.
The IMX93 is placed upon a SOM-module from Variscite, and the kernel is based upon
the kernel from NXP.

Looking at the kernel documentation, it has a disclaimer that not all devices supporting RS485
does support multipoint addressing. 
(https://docs.kernel.org/driver-api/serial/serial-rs485.html)

Is there any plan to implement RS485 multipoint addressing in the Kernel

Are you using NXP i.MX93 EVK board or the board you design yourself? Which version BSP are you using?

We are using a development kit from Variscite at the moment, but are in the progress of designing our own board.

Also, the Kernel we are using is from Variscite, but as I understand it, it is based upon NXPs BSP.
