Added support for DMA transfers. The implementation uses the user watermark to decide whether DMA will be used or not. For watermark 1, DMA will not be used. If watermark is bigger, DMA will be used. Sysfs attributes are created to indicate whether the DMA is used, with hwfifo_enabled, and the current DMA watermark is readable in hwfifo_watermark. Minimum and maximum values are in hwfifo_watermark_min and hwfifo_watermark_max. Signed-off-by:

The module license checker complains about these two so just fix it up. They are both GPLv2, both written by me or using code I extracted while refactoring from the GPLv2 drivers. Cc: Randy Dunlap <rdunlap@infradead.org> Reported-by:

Add necessary casting to several places where we were doing 32-bit arithmetic (unsigned) to produce a 64-bit (unsigned long) result, to prevent the theoretical possibility of a 32-bit overflow during the arithmetic. FYI, these are unsigned long: ctx->param_bytes ctx->allocbytes These are unsigned int: bytes phdr->name_offset phdr->name_length Here is the test program demonstrating why we really need the casts: void main() { unsigned int i; unsigned long il; printf("sizeof(int) =%dn",sizeof(i)); printf("sizeof(long)=%dn",sizeof(il)); i = (unsigned int)((((unsigned long)(1)) << 32) - 1); printf("i = %un", i); il = i+1; printf("adding 1 withOUT cast = %lun", il); il = (unsigned long)i+1; printf("adding 1 WITH cast = %lun", il); } [selltc@mac tmp]$ gcc x.c -o x.out [selltc@mac tmp]$ ./x.out sizeof(int) =4 sizeof(long)=8 i = 4294967295 adding 1 withOUT cast = 0 adding 1 WITH cast = 4294967296 Signed-off-by:Tim Sell <Timothy.Sell@unisys.com> Reported-by:

The imx media driver passes around monotonic timestamps in the deprecated 'timespec' format. This is not a problem for the driver, as they won't overflow, but moving to either timespec64 or ktime_t is preferred. I'm picking ktime_t for simplicity here. frame_interval_monitor() is the main function that changes, as it tries to compare a time interval in microseconds. The algorithm slightly changes here, to avoid 64-bit division. The code previously assumed that the error was at most 32-bit worth of microseconds here, so I'm making the same assumption but add an explicit test for it. Signed-off-by:

struct timeval is deprecated for in-kernel use, and converting this function to use ktime_t makes it simpler as well. Signed-off-by:

Now that the SPDX tag is in all android files, that identifies the license in a specific and legally-defined manner. So the extra GPL text wording can be removed as it is no longer needed at all. This is done on a quest to remove the 700+ different ways that files in the kernel describe the GPL license text. And there's unneeded stuff like the address (sometimes incorrect) for the FSF which is never needed. No copyright headers or other non-license-description text was removed.

It's good to have SPDX identifiers in all files to make it easier to audit the kernel tree for correct licenses. Update the android driver files with the correct SPDX license identifier based on the license text in the file itself. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text.
