Such as virtual display drivers, USB display apapters and ACPI based systems etc. Add fwnode based helpers to fill the niche, this allows part of the display bridge drivers to work across systems. As the fwnode API has wider coverage than DT counterpart and the fwnode graphs are compatible with the OF graph, so the provided helpers can be used on all systems in theory. Assumed that the system has valid fwnode graphs established before drm bridge drivers are probed, and there has fwnode assigned to involved drm bridge instance. Tested on TI BeaglePlay board. v1 -> v2: * Modify it66121 to switch togather * Drop the 'side-by-side' implement * Add drm_bridge_find_next_bridge_by_fwnode() helper * Add drm_bridge_set_node() helper v2 -> v3: * Read kernel-doc and improve function comments (Dmitry) * Drop the 'port' argument of it66121_read_bus_width() (Dmitry) * drm-bridge: sii902x get nuked v3 -> v4: * drm-bridge: tfp410 get nuked * Add platform module alias * Rebase and improve commit message and function comments v4 -> v5: * Modify sii9234, ch7033 and ANX7688 * Trivial fixes Sui Jingfeng (10): drm/bridge: Allow using fwnode APIs to get the next bridge drm/bridge: Add a helper to setup both the of_node and fwnode of drm bridge drm/bridge: simple-bridge: Use fwnode APIs to acquire device properties drm/bridge: display-connector: Use fwnode APIs to acquire device properties drm/bridge: sii902x: Switch to use fwnode APIs to acquire device properties drm-bridge: it66121: Use fwnode APIs to acquire device properties drm/bridge: tfp410: Use fwnode APIs to acquire device properties drm/bridge: sii9234: Use fwnode APIs to abstract DT dependent API away drm/bridge: ch7033: Switch to use fwnode based APIs drm/bridge: anx7688: Switch to use drm_bridge_set_node() helper drivers/gpu/drm/bridge/chrontel-ch7033.c | 14 ++-- drivers/gpu/drm/bridge/cros-ec-anx7688.c | 3 +- drivers/gpu/drm/bridge/display-connector.c | 25 ++++---- drivers/gpu/drm/bridge/ite-it66121.c | 57 ++++++++++------- drivers/gpu/drm/bridge/sii902x.c | 45 +++++-------- drivers/gpu/drm/bridge/sii9234.c | 8 ++- drivers/gpu/drm/bridge/simple-bridge.c | 23 +++---- drivers/gpu/drm/bridge/ti-tfp410.c | 41 ++++++------ drivers/gpu/drm/drm_bridge.c | 74 ++++++++++++++++++++++ include/drm/drm_bridge.h | 18 +++++- 10 files changed, 201 insertions(+), 107 deletions(-) -- 2.34.1
