+STM32 Chrom-Art 2D Graphics Accelerator unit (DMA2D) driver
+================================================
+
+The DMA2D driver implements the following driver-specific controls:
+
+``V4L2_CID_DMA2D_R2M_MODE``
+-------------------------
+ Enable/Disable the Register-To-Memory mode, filling a part or the
+ whole of a destination image with a specific color.
+
+ 1 for enable, 0 for disable.
+
+``V4L2_CID_DMA2D_R2M_COLOR``
+-------------------------------
+ Set the color to fill a part or the whole of a destination image.
+ only used under Register-To-Memory mode, to set the DMA2D_OCOLR register
+ (RED, GREEN, BLUE) which is:
+
+ 31 .. 24 23 .. 16 15 .. 8 7 .. 0
+ ALPHA[7:0] RED[7:0] GREEN[7:0] BLUE[7:0]
