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.

rapidio: Replace 'select' DMAENGINES 'with depends on'
ASoC: sh: Replace 'select' DMAENGINES 'with depends on'
drm: xlnx: dpsub: Fix DMADEVICES Kconfig dependency
