i.MX8ULP generic MU is a different IP compared with previous i.MX chips.
It has different register layout and bit position, but the register name
and bit definitions are almost same with previous i.MX MU.

So we extend the current imx-mailbox driver to support i.MX8ULP.

Peng Fan (4):
dt-bindings: mailbox: imx-mu: add i.MX8ULP MU support
mailbox: imx: replace the xTR/xRR array with single register
mailbox: imx: add xSR/xCR register array
mailbox: imx-mailbox: support i.MX8ULP MU
