Benjamin Gaignard April 7, 2021, 7:35 a.m. UTC
Split the VPU node in two: one for G1 and one for G2 since they are
different hardware blocks.
Add syscon for the hardware control block.
Remove the reg-names property that is useless.
Each VPU node only needs one interrupt.
Change G2 assigned clock to match the specification.
In both nodes all the clocks need to be assigned to make
sure that the control block will be correctly clocked even if
only one device node is enabled.

version 9:
 - Corrections in commit message

version 7:
 - use nxp,imx8m-vpu-ctrl as phandle syscon property name

version 5:
 - use syscon instead of VPU reset
