media: ipu3-cio2: rename cio2 bridge to ipu bridge and move out of ipu3 cio2 bridge was involved along with IPU3. However, in fact all Intel IPUs besides IPU3 CIO2 need this bridge driver. This patch move bridge driver out of ipu3 directory and rename as ipu-bridge. Then it can be worked with IPU3 and other Intel IPUs.

media: ipu3-cio2: Add cio2-bridge to ipu3-cio2 driver Currently on platforms designed for Windows, connections between CIO2 and sensors are not properly defined in DSDT. This patch extends the ipu3-cio2 driver to compensate by building software_node connections, parsing the connection properties from the sensor's SSDB buffer.

media: intel-ipu3: cio2: fix building with large PAGE_SIZE The driver apparently assumes that the device uses the same page size as the CPU, but also assumes that this is 4096 bytes. On architectures with a larger page size like 65536 bytes, we get a warning about an integer overflow: drivers/media/pci/intel/ipu3/ipu3-cio2.c: In function 'cio2_fbpt_entry_init_dummy': arch/arm64/include/asm/page-def.h:28:20: error: large integer implicitly truncated to unsigned type [-Werror=overflow] #define PAGE_SIZE (_AC(1, UL) << PAGE_SHIFT) ^ drivers/media/pci/intel/ipu3/ipu3-cio2.h:404:26: note: in expansion of macro 'PAGE_SIZE' #define CIO2_PAGE_SIZE PAGE_SIZE ^~~~~~~~~ drivers/media/pci/intel/ipu3/ipu3-cio2.c:172:3: note: in expansion of macro 'CIO2_PAGE_SIZE' CIO2_PAGE_SIZE / sizeof(u32) * CIO2_MAX_LOPS; Obviously this won't work, but the driver is also unlikely to ever be used on such an architecture, so the easiest workaround is to define the CIO2_PAGE_SIZE macro to the size that the hardware actually uses.
