	The kernel test robot reports the following error when building on Hexagon with hexagon-allmodconfig. ERROR: modpost: "__hexagon_divdi3" [drivers/media/platform/amlogic/c3/mipi-csi2/c3-mipi-csi2.ko] undefined! The error is caused by using DIV_ROUND_UP() with a 64 bits divisor with a 32-bit dividend, which on Hexagon and clang-17 is resolved with a call to the __hexagon_divdi3() helper function, part of the compiler support library and not available when building Linux. Use DIV_ROUND_UP_ULL() to fix the build error and avoid calling the __hexagon_divdi3() helper function.

2025-05-09	media: platform: Add C3 MIPI CSI-2 driver	Keke Li
	Add a driver for the CSI-2 receiver unit found on the Amlogic C3 SoC. Create a drivers/media/platform/amlogic/c3/ directory to host the driver and the forthcoming support for the Amlogic C3 MIPI adapter and C3 ISP. This driver is used to receive the MIPI data from image sensor.
