i.MX95 Messaging Unit (MU) enables 2 processors on a chip to communicate and coordinate by passing messages (e.g. frame information, event notices and requests) through the MU interface. This patch provides a driver for i.MX95 MU using the common mailbox framework. Currently, SCMI exchanges on i.MX95 uses a mailbox transport with SMT format, and the hardware used is this MU.
Is this ported from Linux ? If so, as of which mainline Linux kernel commit ?
Yes, u-boot/drivers/mailbox/imx-mailbox.c is ported v6.12.8 Linux.
Can you add older iMX SoC support while adding this driver ? It seems imx6..imx95 MU IP look very similar.
This patch-set is only for i.MX95. I can add the older iMX SoC support in the future.
