From: Dillon Min <dillon.minfei@xxxxxxxxx> 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 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. https://lore.kernel.org/linux-media/3acd9ee4-5a58-6ed4-17fe-61596a5252b8@xxxxxxxxx/ v4 link: https://lore.kernel.org/lkml/bc8e1cd1-0013-9062-88b6-fddca535919f@xxxxxxxxx/ 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@xxxxxxxxx/ 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: kernel: commit 9e1ff307c779ce1f0f810c7ecce3d95bbae40896 Author: Linus Torvalds <torvalds@xxxxxxxxxxxxxxxxxxxx> Date: Sun Oct 3 14:08:47 2021 -0700 Linux 5.15-rc4 v4l-utils: commit 700f5ded9c6de2c6dfe5d1b453d85566f95b4f0c Author: Hans Verkuil <hverkuil-cisco@xxxxxxxxx> Date: Sat Oct 2 11:01:05 2021 +0200 test-media: show version info earlier and show cmd args Log the version info earlier and also log the command line arguments.

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 link:

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
