Subject: [PATCH v2 0/3] drm: Add support for Cadence MHDP DPI/DP bridge and J721E wrapper.
Date: Mon, 23 Dec 2019 16:16:39 +0100 [thread overview]
Message-ID: <1577114202-15970-1-git-send-email-yamonkar@cadence.com> (raw)
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.
Version History:
v2:
- Use enum in compatible property of YAML file.
- Add reg-names property to YAML file
- Add minItems and maxItems to reg property in YAML.
- Remove cdns_mhdp_link_probe function to remove
duplication of reading dpcd capabilities.
This patch series is dependent on PHY DisplayPort configuration patch [1]
