Tue Oct 26 00:11:12 PDT 2021
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
v7:
- fix compile test reported by lkp at intel.com, thanks.
- collect acked-by, reviewed-by from Gabriel, Patrice.
v6 link:
https://lore.kernel.org/lkml/1634633003-18132-1-git-send-email-dillon.minfei@gmail.com/
v6:
- use 2592x2592 instead of 0x3fff, 0xffff. [PATCH v6 10/10]
- add space in '(V4L2_CID_BASE+43)' to avoid checkpatch warrnings. [PATCH v6 08/10]
v5 link:
https://lore.kernel.org/lkml/1634533488-25334-1-git-send-email-dillon.minfei@gmail.com/
v5:
- rebase to media_tree https://git.linuxtv.org/media_tree.git/
- remove unused log from dma2d driver to avoid spam kernel log.
- fix 0xFFFFFF to 0xffffff, 2^24 to 2^24 -1, etc.
- introduce patch "media: v4l2-ctrls: Add V4L2_CID_COLORFX_CBCR max setting"
to add V4L2_CID_COLORFX_CBCR entry.
- thanks to Hans's patch, open nullptr check in v4l2-compliance, update new
test result. thanks.

v4 link:
https://lore.kernel.org/lkml/bc8e1cd1-0013-9062-88b6-fddca535919f@xs4all.nl/
v4:
- replace V4L2_COLORFX_SET_ARGB, V4L2_CID_COLORFX_ARGB to
V4L2_COLORFX_SET_RGB, V4L2_CID_COLORFX_RGB since Alpha paramter not used
in current. thanks Hans.
v3 link:
https://lore.kernel.org/lkml/1633689012-14492-1-git-send-email-dillon.minfei@gmail.com/
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:
- 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.

v1:
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().
with v4l2-compliance test log (with above modification):
since the stm32f469-disco ram limitation, there are 25 failed on
dma_alloc_coherent()
Really appreciate if someone can help to test this patch on the STM32429I-EVAL
evaluation board (https://www.st.com/en/evaluation-tools/stm32429i-eval.html)
