Subject: [PATCH v2 0/5] Support Nuvoton NPCM Video Capture/Encode Engine

Changes in v2: Add Hextile document and locate with vendor formats.

This patch series add DTS node, dt-bindings document and drivers for Video
Capture/Differentiation Engine (VCD) and Encoding Compression Engine (ECE)
present on Nuvoton NPCM SoCs.

VCD can capture/differentiate video data from digital or analog sources,
then ECE will compress the data into HEXTILE format.

HEXTILE compressed format is defined in Remote Framebuffer Protocol (RFC
6143) and is used by VNC features, so we also add a patch to support it.

Marvin Lin (5):
  arm: dts: Add node for NPCM Video Capture/Encode Engine
  dt-bindings: media: Add dt-bindings for NPCM Video Capture/Encode
    Engine
  dt-bindings: arm/npcm: Add dt-bindings for Graphics Core Information
  media: Add HEXTILE compressed format
  drivers: media: platform: Add NPCM Video Capture/Encode Engine driver
