[PATCH v2 0/7] media: venus: Add QCM2290 support with AR50_LITE core

[Jorge Ramirez-Ortiz <jorge.ramirez@oss.qualcomm.com>]

Changes since v1:
- Add IS_HFI macro usage
- Move schema patch to top
- Fix commit messages

This patch series adds support for the Venus video decoder/encoder block
present on the Qualcomm QCM2290.

The QCM2290 integrates an AR50_LITE core, a low-power implementation of
Venus supporting H.264, HEVC (H.265), and VP9 decoding.

The series includes:
  • DT binding schema for qcom,qcm2290-venus
  • SoC integration via qcm2290.dtsi
  • Resource table definitions and frequency scaling
  • Platform capability registration for the AR50_LITE core

Decoding was verified on the QCOM RB1 platform using GStreamer with V4L2-based
decode plugins. The following pipelines were used for playback 1280x720 and
1920x1080 H.264, HVEC and VP9 videos from https://www.elecard.com/videos.
