Hello,
This small series fixes a Kconfig dependency issue with the recently merged Xilixn DPSUB DRM/KMS driver. The fix is in patch 3/3, but requires a separate fixes in patches 1/3 and 2/3 to avoid circular dependencies:
drivers/i2c/Kconfig:8:error: recursive dependency detected! drivers/i2c/Kconfig:8: symbol I2C is selected by FB_DDC drivers/video/fbdev/Kconfig:63: symbol FB_DDC depends on FB drivers/video/fbdev/Kconfig:12: symbol FB is selected by DRM_KMS_FB_HELPER drivers/gpu/drm/Kconfig:80: symbol DRM_KMS_FB_HELPER depends on DRM_KMS_HELPER drivers/gpu/drm/Kconfig:74: symbol DRM_KMS_HELPER is selected by DRM_ZYNQMP_DPSUB drivers/gpu/drm/xlnx/Kconfig:1: symbol DRM_ZYNQMP_DPSUB depends on DMA_ENGINE drivers/dma/Kconfig:44: symbol DMA_ENGINE depends on DMADEVICES drivers/dma/Kconfig:6: symbol DMADEVICES is selected by SND_SOC_SH4_SIU sound/soc/sh/Kconfig:30: symbol SND_SOC_SH4_SIU is selected by SND_SIU_MIGOR sound/soc/sh/Kconfig:60: symbol SND_SIU_MIGOR depends on I2C For a resolution refer to Documentation/kbuild/kconfig-language.rst subsection "Kconfig recursive dependency limitations"
Due to the DPSUB driver being merged in v5.9, this is a candidate fix for v5.9 as well. 1/3 and 2/3 can be merged independently, 3/3 depends on the first two. What's the best course of action, can I merge this all in a single tree, or should the rapidio and ASoC patches be merged independently early in the -rc cycle, and the DRM patch later on top ? I don't expect conflicts (especially in 2/3 and 3/3), so merging the whole series in one go would be simpler in my opinion.
Compared to v1, commit messages have been fixed to mention DMADEVICES instead of DMAENGINES.

Enabling a whole subsystem from a single driver 'select' is frowned upon and won't be accepted in new drivers, that need to use 'depends on' instead. Existing selection of DMADEVICES will then cause circular dependencies. Replace them with a dependency.

The dpsub driver uses the DMA engine API, and thus selects DMA_ENGINE to provide that API. DMA_ENGINE depends on DMADEVICES, which can be deselected by the user, creating a possibly unmet indirect dependency:
WARNING: unmet direct dependencies detected for DMA_ENGINE Depends on [n]: DMADEVICES [=n] Selected by [m]: - DRM_ZYNQMP_DPSUB [=m] && HAS_IOMEM [=y] && (ARCH_ZYNQMP || COMPILE_TEST [=y]) && COMMON_CLK [=y] && DRM [=m] && OF [=y]
Add a dependency on DMADEVICES to fix this.

Thank you.
As Mark as queued the sound fix in his for-next branch for v5.9, could you queue the dmaengine fix for v5.9 too ?

Dmaengine? I see three patches none of which touch dmaengine.. Did I miss something?

I'm not sure what I was thinking... It's the rapidio patch that needs to be merged.
Matt, Alexandre, can you either merge the patch as a v5.9 fix, or give me an ack to get it merged through the DRM tree ?

Matt, Alexandre,
Gentle ping. As this should be fixed in v5.9, a quick reply would be really appreciated. Otherwise I'll have to bundle the rapidio fix with the DPSUB fix, and get them both merged through the DRM/KMS tree without your ack.

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
