The Wave5 codec driver is a stateful encoder/decoder.
It is found on the J721S2 SoC, JH7100 SoC, ssd202d SoC. Etc.
But current test report is based on J721S2 SoC and pre-silicon FPGA.
The driver currently supports V4L2_PIX_FMT_HEVC, V4L2_PIX_FMT_H264.
This driver has so far been tested on J721S2 EVM board and pre-silicon
FPGA.
Testing on J721S2 EVM board shows it working fine both decoder and
encoder.
The driver is successfully working with gstreamer v4l2 good-plugin
without any modification.

changes since v9:
* Move from staging to the media directory
* Move coda driver to sub-directory
* Fixes:
* Use platform_get_irq instead of platform_get_resource to fetch the IRQ
* General cleanups:
* Add missing error messages to error conditions
* Improve messages/variable names/comments, align parameter names across the driver
* Use macros instead of magic numbers in multiple occassions
* Reduce code duplication in multiple places
* Fix whitespace, newline and tab alignment issues
* Remove unused struct fields & commented out code
* Convert signed integers to unsigned if signed is not necessary
* Convert int/unsigned int to s32/u32, when the variable is assigned to the
return of a register read or provided as a parameter for a register write
(and vice versa)
* Fix incorrect bitwise operators where logical operators are appropriate
* Multiple smaller changes
* Generalization:
* Add new helper file providing generalized routines for vpu-dec & vpu-enc
* Generalize luma & chroma table size calculation and stride calculation
* Resource cleanup and error handling:
* Add error handling to all calls with ignored return codes
* Handle DMA resource cleanup properly
* Fix insufficient instance cleanup while opening dec/enc
changes since v8:
* add 'wave5' to DEV_NAME
* update to support Multi-stream
* update to support loop test/dynamic resolution change
* remove unnecessary memset, g_volatile, old version option
changes since v7:
* update v4l2-compliance test report
* fix build error on linux-kernel 5.18.0-rc4
changes since v6:
* update TODO file
* get sram info from device tree
changes since v5:
* support NV12/NV21 pixelformat for encoder and decoder
* handle adnormal exit and EOS
changes since v4:
* refactor functions in wave5-hw and fix bug reported by Daniel Palmer
* rename functions and variables to better names
* change variable types such as replacing s32 with u32 and int with bool
* as appropriate
changes since v3:
* Fixing all issues commented by Dan Carpenter
* Change file names to have wave5- prefix
* In wave5_vpu_probe, enable the clocks before reading registers, as
* commented from Daniel Palmer
* Add more to the TODO list,
changes since v2:
Main fixes includes:
* change the yaml and dirver code to support up to 4 clks (instead of
* one)
* fix Kconfig format
* remove unneeded cast,
* change var types
* change var names, func names
* checkpatch fixes
changes since v1:
Fix changes due to comments from Ezequiel and Dan Carpenter. Main fixes
inclueds:
* move all files to one dir 'wave5'
* replace private error codes with standard error codes
* fix extra spaces
* various checkpatch fixes
* replace private 'DPRINTK' macro with standard 'dev_err/dbg ..'
* fix error handling
* add more possible fixes to the TODO file
