[PATCH v2 1/3] dt-bindings: mailbox: fix the mpfs' reg property

Conor Dooley
2022-08-24T07:08:55Z

The "data" region of the PolarFire SoC's system controller mailbox is
not one continuous register space - the system controller's QSPI sits
between the control and data registers. Split the "data" reg into two
parts: "data" & "control".

Fixes: 213556235526 ("dt-bindings: soc/microchip: update syscontroller compatibles")
Fixes: ed9543d6f2c4 ("dt-bindings: add bindings for polarfire soc mailbox")
