Subject: [PATCH v4] Add support for KeemBay DRM driver
Date: Thu, 30 Jul 2020 13:44:43 -0700 [thread overview]
Message-ID: <1596141884-29868-1-git-send-email-anitha.chrisanthus@intel.com> (raw)
This is a new DRM driver for Intel's KeemBay SOC.
The SoC couples an ARM Cortex A53 CPU with an Intel
Movidius VPU.
This driver is tested with the KMB EVM board which is the refernce baord
for Keem Bay SOC. The SOC's display pipeline is as follows
+--------------+ +---------+ +-----------------------+
|LCD controller| -> |Mipi DSI | -> |Mipi to HDMI Converter |
+--------------+ +---------+ +-----------------------+
LCD controller and Mipi DSI transmitter are part of the SOC and
mipi to HDMI converter is ADV7535 for KMB EVM board.
The DRM driver is a basic KMS atomic modesetting display driver and
has no 2D or 3D graphics.It calls into the ADV bridge driver at
the connector level.
Only 1080p resolution and single plane is supported at this time.
The usecase is for debugging video and camera outputs.
Device tree patches are under review here

Changes since v1:
- Removed redundant license text, updated license

- renamed global vars and removed extern in c
- Used upclassing for dev_private
- Used drm_dev_init in drm device create
- minor cleanups
Changes since v2:
- squashed all commits to a single commit
- logging changed to drm_info, drm_dbg etc.
- used devm_drm_dev_alloc()
- removed commented out sections and general cleanup
Changes since v3:
