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 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.
