I will update the prefix to "media: dt-bindings: nxp,imx8-jpeg:". as you suggested in v2. >> Changes since v3: >> - Add items for clocks (per Krzysztof's feddback) >> - Add description for clocks (per Conor's feddback to the other similar patch from Alexander) >> - Add "media:" to the subject > Where? It was there before, so what did you change? I started from v3 here: https://lore.kernel.org/linux-devicetree/20230912163810.1750488-1-festevam@gmail.com/ The subject was: "[PATCH v3 1/3] dt-bindings: imx8-jpeg: Add clocks entries", I had just added "media:". Anyways, will update it again. >> + clocks: >> + description: >> + The JPEG decoder/encoder requires two clocks for it's wrapper (AXI and APB), >> + and one clock for it's core engine (AXI, same source as for the wrapper) > Description is now redundant, drop it. Ok, I will do so in v5. Thanks a lot for feedback, Mirela
