From: Benjamin Gaignard <benjamin.gaignard@collabora.com> 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 compatible with older DT the driver is still capable to use the 'ctrl' reg-name even if it is deprecated now.
