[PATCH 0/4] Reset driver for IMX8MQ VPU hardware block

[Benjamin Gaignard]

The two VPUs inside IMX8MQ share the same control block which can be see
as a reset hardware block.
In order to be able to add the second VPU (for HECV decoding) it will be
more handy if the both VPU drivers instance don't have to share the
control block registers. This lead to implement it as an independ reset 
driver and to change the VPU driver to use it.

Benjamin Gaignard (4):
  dt-bindings: reset: IMX8MQ VPU reset
  reset: Add reset driver for IMX8MQ VPU block
  media: hantro: Use reset driver
  arm64: dts: imx8mq: Use reset driver for VPU hardware block
