The kernel test robot has already reported build errors. I assume the remaining patches are DTS ones? If so, I do not see how clock drivers would require DTS change to build correctly. Do you have a pointer to the reported build errors? My understanding about the build dependency is the opposite, i.e. the DTS changes require clock defines merged by Abel to build? In that case, I suggest Abel pick up the whole series with my ack on DTS changes. Acked-by: Shawn Guo <shawnguo@kernel.org> Alternatively, I can pick up the remaining patches after clock changes land on mainline (the next -rc1).

NAK, why did you create patchset forcing DTS to be put into the driver subsystem? It is even beyond ABI break.

I was surprised to see that the series has been removed from linux-next. It’s been 8 months since the first version dated September 28, 2024. The most critical phase was version 3 - https://lore.kernel.org/all/20241106090549.3684963-1-dario.binacchi@amarulasolutions.com/ - where two key issues emerged: 1 The CCM design is flawed because "in the current design, CCM is taken as the producer of CLK_IMX8M_VIDEO_PLL, not the consumer." 2 A driver for anatop needs to be implemented because "using clocks to replace fsl,ssc-clocks is possible under CCM mode, but you need to develop the fsl,imx8mm-anatop clock driver." These development guidelines, agreed upon with Krzysztof and Peng, enabled a coherent implementation of both the DT bindings and the code. The following versions, from v4 to v8, were necessary to review and refine those implementations, bringing us to January 2025. At that point, Peng opened a separate pull request - https://github.com/devicetree-org/dt-schema/pull/154 - for the definition of general-purpose DT bindings for spread spectrum handling, which ended up invalidating mine. While waiting for his pull request to be accepted, I submitted version 9, trying to at least get the patches for the anatop driver merged, eventually reaching version 12. This final version was merged, but then a few days ago it was dropped. As it stands now: - We still don’t have proper spread spectrum handling - Peng’s pull request has been stalled since February 20 - We don’t have a driver for anatop - The CCM design remains flawed - Not even the first 4 patches of the series were merged — these were simply a replication for i.MX8MM and i.MX8MP of patch bedcf9d1dcf88 ("clk: imx: rename video\_pll1 to video\_pll"), which was already merged some time ago. Could you please let me know if you're still interested in this series? If so, could you suggest how to resolve the issues that led you to drop it?

I don't think so: The answers related to the errors encountered during DTC compilation: https://lore.kernel.org/oe-kbuild-all/CABGWkvp7n=Or-OqnLoOJsQQCHF+=8eQ9EV5=O+Qp4sQF49_DbA@mail.gmail.com/ https://lore.kernel.org/all/CABGWkvqfyH=dcuw6EDZaFVVebj8SZhJF0P944+mmzL5YK3-Pug@mail.gmail.com/ The patch to fix the regression reported by Mark Brown: https://lore.kernel.org/all/20250516134945.14692-1-dario.binacchi@amarulasolutions.com/ Also successfully tested by him. And when I didn’t reply, I was expecting the maintainers to handle it — as Peng Fan had requested in version 10: https://lore.kernel.org/all/20250314093503.GD12210@nxa18884-linux/ I may have made some mistakes, but don't tell me I never replied.

This version keeps the version v9 patches that can be merged and removes the patches that will need to be modified in case Peng's PR https://github.com/devicetree-org/dt-schema/pull/154 is accepted. The idea is to speed up the merging of the patches in the series that have already been reviewed and are not dependent on the introduction of the assigned-clocks-sscs property, and postpone the patches for spread spectrum to a future series once it becomes clear what needs to be done. Specifically, the patches: 01/18 dt-bindings: clock: imx8mm: add VIDEO_PLL clocks 02/18 clk: imx8mm: rename video_pll1 to video_pll 03/18 dt-bindings: clock: imx8mp: add VIDEO_PLL clocks 04/18 clk: imx8mp: rename video_pll1 to video_pll are a replica for i.MX8MM and i.MX8MP of the patch for i.MX8MM bedcf9d1dcf88 ("clk: imx: rename video_pll1 to video_pll"), which was merged some time ago. The patches are split into four because, during the review, Krzysztof asked me to separate the driver modifications from the dt-bindings changes. All the other patches in the series, from 5 to 18, are necessary for the implementation of the anatop driver for i.MX8M{M,N,P}. The review of this series has taken a long time, partly due to misunderstandings arising from incorrect design choices. As Peng stated in [1]: "In current design, CCM is taken as producer of CLK_IMX8M_VIDEO_PLL, not consumer." These patches fix this issue by ensuring that the PLLs are now produced by Anatop and consumed by CCM, aligning with the hardware logic. Finally, a clarification: I decided to keep the same title for the series despite having removed all the patches for spread spectrum support in order to maintain a clear connection with the previous versions.

The dt-bindings have been moved from fsl,imx8m-anatop.yaml to imx8m-clock.yaml. The anatop device (fsl,imx8m-anatop.yaml) is indeed more or less a syscon, so it represents a memory area accessible by ccm (imx8m-clock.yaml) to setup the PLLs. - Patches {3,5}/8 have been added in version 3. - Patches {4,6,8}/8 use ccm device node instead of the anatop one. Changes in v2: - Add "allOf:" and place it after "required:" block, like in the example schema. - Move the properties definition to the top-level. - Drop unit types as requested by the "make dt_binding_check" command.
