Subject: [PATCH v2, 0/6] support mt8188 h264 encoder

mt8188 encoder hardware has a change compared to the previous
chipsets, it supports 34-bit iova access. For 34-bit iova, the
encoder driver needs to write all 34 bits to hardware, otherwise
encoder will encode fail.

Patch 1 add the 34-bit iova supporting in driver.
Patch 2~3 add dt-bindings and driver compatible and private data.
Patch 4~6 some modification for in driver.

---
compare with v1:
 - split vpu_enc_encode function into 32bits and 34bits.
 - some review comments modification.

Irui Wang (6):
  media: mediatek: vcodec: Add encoder driver support for 34-bit iova
  dt-bindings: media: mediatek: vcodec: Add encoder dt-bindings for
    mt8188
  media: mediatek: vcodec: Add mt8188 encoder driver
  media: mediatek: vcodec: Remove encoder driver get IRQ resource
  media: mediatek: vcodec: Fix bitstream crop information error
  media: mediatek: vcodec: Use ctx vb2_queue mutex instead of device
    mutex
