[PATCH v4 0/4] mailbox: imx: support i.MX95 ELE/V2X MU

From: Peng Fan (OSS)
Date: Thu Jan 25 2024 - 00:16:03 EST


- Add dt-bindings
- i.MX95 ELE/V2X use same register layout as i.MX8ULP S4 MU, but
the TR/RR num is different. To make code reusable and not add too much
macros, add runtime detect number of TR and RR by reading PAR_OFF
registers.
- Add i.MX95 ELE/V2X MU entry in driver
