Subject: [PATCH v3 0/8] Add support for DMA2D of STMicroelectronics STM32 Soc series
From: Dillon Min <dillon.minfei@...il.com>
This patchset introduces a basic support for DMA2D Interface
of STMicroelectronics STM32 SoC series.
This first basic support implements R2M, M2M, M2M_PFC
M2M_BLEND support will be added later on.
This has been tested on STM32469-DISCO board.
history
v3:
- use V4L2_COLORFX_SET_ARGB, V4L2_CID_COLORFX_ARGB to pass argb paramter to
the dma2d driver, instead of add stm32 private ioctl.
- some v2's patch are removed in this version.
- "[PATCH v2 7/9] media: docs: add doc for the stm32 dma2d driver"
- "[PATCH v2 8/9] media: v4l: uapi: Add user control base for stm32 dma2d
controls"
- dma2d's driver changes based on Hans's review result. detail can be found at
"media: stm32-dma2d: STM32 DMA2D driver"
- add stm32 clk drivers bugfix, ltdc clock disabled after kenerl boot up.
v3 based on kernel and v4l-utils git:

v2 link:
https://lore.kernel.org/lkml/1626341068-20253-11-git-send-email-dillon.minfei@gmail.com/
v2:
- update v4l2-compliance to SHA: a4f2e3a6f306 2021-07-13 08:04:15
the test results at below [1].
- introduce Documentation/userspace-api/media/drivers/stm32-uapi.rst
to explain the detail of dma2d's ioctl.
- reserved 16 ioctls from v4l2-controls.h for stm32, introduce stm32-media.h.
- collect Reviewed-by tag from Rob Herring.
- update dma2d driver from Hans's review. the details can be found
at related patches.

The commit based on kernel(master): c3d0e3fd41b7f0f5d5d5b6022ab7e813f04ea727
Note for v4l2-compliance tool on nu-mmu platform:
I add two change based on v4l-utils since commit:
f0c7e3d71eaf4182bae7eb3ee0e43b4eeb047ea9
- change fork() to vfork() in v4l2-test-controls.cpp
since no-mmu platform don't include fork().
- bypass VIDIOC_QUERYCAP nullptr check
I'm not sure if this is the bug from my cross compile tool
which created by buildroot. user area's nullptr can't be
detected by kernel side, i was try to add access_ok()
in v4l2-ioctl.c, but no help
If this case must be fixed, i will continue to debug it.
the error log:
...
fail: v4l2-compliance.cpp(623): doioctl(node, VIDIOC_QUERYCAP, nullptr) !=
EFAULT
..

Really appreciate if someone can help to test this patch on the STM32429I-EVAL
