Hello!

This is the implementation of the Chips&Media "CODA988" video codec support
within v4l2 driver for coda. Support for the following codecs
was implemented:
 * h264:   decoder & encoder
 * h263:   decoder & encoder
 * mpeg4:  decoder & encoder
 * vp8dec: decoder

Support for the following formates was implemented:
 * yuv420p(I420)
 * yvu420p(YV12)
 * NV12
 * NV21

Also the following features and fixes were implemented for coda988:
 * special config for mem_ctrl
 * special config for encoder header (sps and pps)
 * special set profile_idc
 * special set RC config
 * special set QP
 * special set slice mode
 * special set Motion Extimation (ME)
 * v4l2_ctrl for h264 profile 
 * v4l2_ctrl for h264 level
 * v4l2_ctrl for h.264 RC mode
 * v4l2_ctrl for h.264 skipFrame
 * v4l2_ctrl for h.264 i-frame min/max qp
 * v4l2_ctrl for h.264 p-frame min/max qp
 * v4l2_ctrl for h.264 entropy mode
 * v4l2_ctrl for h.264 8x8transform
 * v4l2_ctrl for h.264 i-frame period
 * v4l2_ctrl for h.264 Access Unit Delimiter(AUD)
 * v4l2_ctrl for h.264 me x/y search range
 * v4l2_ctrl for h.264 intra refresh period
 * v4l2_ctrl for h.263 intra/inter qp
 * v4l2_ctrl for h.263 min/max qp
 * v4l2_ctrl for mpeg4 min/max qp

During adding support for "CODA988" we also did some extra work
related to refactoring and improvement of generic part of C&M coda
driver:
 * Improve error checking for probe, irq-handle and etc.
 * Update work with resets
 * Replace hard_irq by threaded_irq
 * Remove double setting of stop flag
 * Improve some prints
 * Fix loglevel to avoid performance failure
 * Fix support of MPEG4 levels
 * Fix setting gamma for h264enc
 * Update default velues of QP for mpeg4 I/P
 * Other minor fixes

Sergey Khimich (18):
  media: coda: Add print if irq isn't present
  media: coda: Use get_array to work use multiple reset
  dt-bindings: media: coda: Fix resets count
  media: coda: Add check result after reset
  media: coda: using threaded_irq for 0 (bit) interrupt
  media: coda: Add reset device before getting interrupt
  media: coda: Add fake IRQ check
  media: coda: Add log to finish_encode if buffer is too small
  media: coda: Fix max h.264 level for CODA_DX6
  media: coda: Remove double setting of stop flag
  media: coda: Print size of encoded buff in other place
  media: coda: Fix loglevel for seq mismatch print
  media: coda: Fix support for all mpeg4 levels
  media: coda: Fix handling wrong format in coda_try_fmt
  media: coda: Use v4l2_ctrl to set gamma for h264enc
  media: coda: Update default velues of QP for mpeg4 I/P
  media: coda: Use preferred usleep_range than udelay
  media: coda: add support coda988 enc and dec
