This patch series adds new DRM driver for Cadence Display Port. The Cadence Display Port is also referred as MHDP (Mobile High Definition Link, High-Definition Multimedia Interface Display Port) Cadence Display Port complies with VESA DisplayPort (DP) and embedded Display Port (eDP) standards This driver implements Single Stream Transport (SST) support. Adds Texas Instruments SoC J721e specific wrapper and adds the device tree bindings in YAML format The patch series has three patches which applies the changes in the below sequence 1. 001-dt-bindings-drm-bridge-Document-Cadence-MHDP-bridge-bindings-in-yaml-format Documents the bindings in yaml format. 2. 002-drm-bridge-Add-support-for-Cadence-MHDP-bridge This patch adds new DRM driver for Cadence MHDP Display Port. The patch implements supports for single stream transport mode. 3. 003-drm-mhdp-add-j721e-wrapper Add Texas Instruments (TI) j721e wrapper for mhdp. The wrapper configures mhdp clocks and muxes as required by SoC.
