Subject: [PATCH] drm: bridge: add Cadence MHDP HDMI/DP API
|
|
|
|
Changes made in the low level driver (cdn-dp-reg.*):
|
|
- moved it to from drivers/gpu/drm/rockchip to
|
|
drivers/gpu/drm/bridge/cadence/cdns-mhdp-common.c and
|
|
include/drm/bridge/cdns-mhdp-common.h
|
|
- functions for sending/receiving commands are now public
|
|
- added functions for reading registers and link training adjustment
|
|
|
|
Changes made in RK's driver (cdn-dp-core.*):
|
|
- Moved audio_info and audio_pdev fields from cdn_dp_device to
|
|
cdns_mhdp_device structure.
