Introducing the G2 hevc video decoder requires modifications of the bindings to
allow
one node per VPU.
VPUs share one hardware control block which is provided as a phandle on
a syscon.
Each node has now one reg and one interrupt.
Add a compatible for G2 hardware block: nxp,imx8mq-vpu-g2.
To be
The IMX8MQ got two VPUs but until now only G1 has been enabled.
This series aim to add the second VPU (aka G2) and provide basic
HEVC decoding support.
To be able to decode HEVC it is needed to add/update some of the
structures in the uapi. In addition of them one HANTRO dedicated
control is requ
In order to be able to share the control hardware block between
VPUs use a syscon instead a ioremap it in the driver.
To keep the compatibility with older DT if 'nxp,imx8mq-vpu-ctrl'
phandle is not found look at 'ctrl' reg-name.
With the method it becomes useless to provide a list of register
names
Add fields and flags as they are defined in
7.4.3.3.1 "General picture parameter set RBSP semantics of the
H.265 ITU specification.

Change hantro_codec_ops run prototype from 'void' to 'int'.
This allows the driver to cancel the job if an error occurs while configuring
the hardware.

The HEVC HANTRO driver needs to know the number of bits to skip at
the beginning of the slice header.
That is a hardware specific requirement so create a dedicated control
