Subject: [PATCH v4 0/5] Wave515 decoder IP support

Initial support for Wave515 multi-decoder IP among other refinements.
This was tested on FPGA prototype, so wave5_dt_ids[] was not expanded.

fluster score for JCT-VC-HEVC_V1 testsuite with
GStreamer-H.265-V4L2-Gst1.0 decoder is 132/147

The issue with Main10 tests is that fluster expects decoded file to be
in yuv420p10le format while this driver decodes HEVC Main10 into 8-bit
yuv420p. Though result is looks alright to the naked eye, proper
decoding into yuv420p10le is to be added.

The rest failed fluster tests are common with Wave521.

ChangeLog:
  v1:
https://lore.kernel.org/linux-media/20240318144225.30835-1-brnkv.i1@gmail.com/
  v2:
https://lore.kernel.org/linux-media/20240325064102.9278-1-brnkv.i1@gmail.com/
    * drop patch "dt-bindings: media: cnm,wave521c: drop resets restriction"
      The only user of Wave5 in mainline is TI K3 boards, thus there is
      no real need to alter dt-bindings
    * in patch "media: chips-media: wave5: support decoding HEVC Main10 profile"
      add check for flag "support_hevc10bit_dec"
    * in patch "media: chips-media: wave5: support reset lines" move
      reset_control_deassert() out of else branch, add
      reset_control_assert() to probe error path.
    * rework patch "media: chips-media: wave5: drop "sram-size" DT prop"
       - don't move alloc/free form device open/close
       - intead of exact configuration of reserved SRAM memory in DT and
	 allocating all of it, allocate all available SRAM memory up to
	 WAVE5_MAX_SRAM_SIZE from whatever pool provided.
    * adjust patch "media: chips-media: wave5: support Wave515 decoder"
      according to changes in patches
      "media: chips-media: wave5: support decoding HEVC Main10 profile" and
      "media: chips-media: wave5: drop "sram-size" DT prop"
  v3:
https://lore.kernel.org/linux-media/20240405164112.24571-1-brnkv.i1@gmail.com/
    * reword patch "media: chips-media: wave5: separate irq setup routine"
      a bit.
    * in patch "media: chips-media: wave5: drop "sram-size" DT prop"
       - move MAX_SRAM_SIZE define into match_data->sram_size
       - add placeholders for validation that allocated SRAM memory is
	 enough to encode/decode bitstream of given resolution before
	 setting W5_USE_SEC_AXI and W5_CMD_ENC_PIC_USE_SEC_AXI registers
       - reword accordingly
    * in patch "media: chips-media: wave5: support Wave515 decoder"
       - add comments around SRAM memory allocation/freeing about
	 Wave515 specifics
       - add comments about BSOPTION_RD_PTR_VALID_FLAG bit in
	 W5_BS_OPTION register
       - add W[AVE]521_ prefix to defines, for wich there are W[AVE]515_
	 alternatieves
       - add semi-magic Wave515 specific formulas to estimate SRAM usage
  v4:
    * rebase onto next-20240415, no functional changes
