Introducing G2 hevc video decoder lead to modify the bindings to allow to get one node per VPUs. VPUs share one hardware control block which is provided as a phandle on an syscon. Each node got 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 'ctrl' reg-name even if it is deprecated now. Signed-off-by: Benjamin Gaignard <benjamin.gaignard@collabora.com> --- version 5: - This version doesn't break the backward compatibilty between kernel and DT. .../bindings/media/nxp,imx8mq-vpu.yaml | 53 ++++++++++++------- 1 file changed, 34 insertions(+), 19 deletions(-)
