V2:
No change
V3:
- Correct license headers
- Use more generic name core instead of jasper for base registers
- Add Comment for forward declarations
- Simplify quantization table calculations
- Use v4l2_apply_frmsize_constraints for updating framesize and remove
unrequired functions
- Place TODO at top of file and in commit message too
- Use dev_err_probe helper in probe function
- Fix return value checking for failure scenarios in probe function
- Use v4l2_err/info/warn helpers instead of dev_err/info/warn helpers
- Fix unexpected indentation
- Correct commit message
- Remove dependency on ARCH_K3 as driver is not specific to that
V4:
- Fix issue with default params setting
- Correct v4l2 error prints
- Simplify register write functions with single statement return values
- Remove unrequired error checks from get_queue()
- Drop explicit device_caps setting as it is already taken care by v4l2
core
- Remove unrequired multiplanar checks and memset from s_fmt, g_fmt callback
functions
- Fix try_fmt callback to not update the queues
- Remove unrequired contiguous format attribute from queue_init
- Use dynamic allocation for video_device and remove unrequired
assignments in probe()
- Remove unrequired checks from queue_setup function
- Return queued buffers back if start_streaming fails
- Use ARRAY_SIZE in place of hard-coding
- Use huffman and quantization tables from reference header file
V5:
- Sort the #includes alphabetically in e5010-jpeg-enc.c
- Update commit message to point to V5 test reports

+ This is a video4linux2 M2M driver for Imagination E5010 JPEG encoder,
+ which supports JPEG and MJPEG baseline encoding of YUV422 and YUV420
+ semiplanar video formats, with resolution ranging from 64x64 to 8K x 8K
+ pixels. The module will be named as e5010_jpeg_enc.
