Long time, few but important changes. Changes since v3: * converted binding schema file to json-schema ("YAML") It now validates (itself and the dts) like a charm ;-) Input port0 is mandatory, output port1 is optional. * Enric Balletbo i Serra waived analogix-anx6345 module ownership to icenowy Since they both agree, I won't interfere. Changes from v2: * use SPDX-IDs throughout * removed the panel output again, as it was not what Maxime had in mind. At least the Teres-I does very well without. * binding clarifications and cosmetic changes as suggested by Andrzej Changes from v1: * fixed up copyright information. Most code changes are only moves and thus retain copyright and module ownership. Even the new analogix-anx6345.c originates from the old 1495-line analogix-anx78xx.c, with 306 insertions and 987 deletions (ignoring the trivial anx78xx -> anx6345 replacements) 306 new vs. 508 old... * fixed all minor formatting issues brought up * merged previously separate new analogix_dp_i2c module into existing analogix_dp * split additional defines into a preparatory patch * renamed the factored-out common functions anx_aux_* -> anx_dp_aux_*, because anx_...aux_transfer was exported globally. Besides, it is now GPL-only exported. * moved chip ID read into a separate function. * keep the chip powered after a successful probe. (There's a good chance that this is the only display during boot!) * updated the binding document: LVTTL input is now required, only the output side description is optional. Laurent: I have also looked into the drm_panel_bridge infrastructure, but it's not that trivial to convert these drivers to it. Changes from the respective previous versions: * the reset polarity is corrected in DT and the driver; things should be clearer now. * as requested, add a panel (the known innolux,n116bge) and connect the ports. * renamed dvdd?? to *-supply to match the established scheme * trivial update to the #include list, to make it compile in 5.2 Icenowy Zheng (4): drm/bridge: move ANA78xx driver to analogix subdirectory drm/bridge: split some definitions of ANX78xx to dedicated headers drm/bridge: extract some Analogix I2C DP common code drm/bridge: Add Analogix anx6345 support Torsten Duwe (3): drm/bridge: Prepare Analogix anx6345 support dt-bindings: Add ANX6345 DP/eDP transmitter binding arm64: dts: allwinner: a64: enable ANX6345 bridge on Teres-I .../bindings/display/bridge/anx6345.yaml | 92 +++ .../boot/dts/allwinner/sun50i-a64-teres-i.dts | 45 +- drivers/gpu/drm/bridge/Kconfig | 10 - drivers/gpu/drm/bridge/Makefile | 4 +- drivers/gpu/drm/bridge/analogix-anx78xx.h | 710 ------------------ drivers/gpu/drm/bridge/analogix/Kconfig | 22 + drivers/gpu/drm/bridge/analogix/Makefile | 4 +- drivers/gpu/drm/bridge/analogix/analogix-anx6345.c | 793 +++++++++++++++++++++ .../drm/bridge/{ => analogix}/analogix-anx78xx.c | 146 +--- drivers/gpu/drm/bridge/analogix/analogix-anx78xx.h | 255 +++++++ .../gpu/drm/bridge/analogix/analogix-i2c-dptx.c | 165 +++++ .../gpu/drm/bridge/analogix/analogix-i2c-dptx.h | 258 +++++++ .../drm/bridge/analogix/analogix-i2c-txcommon.h | 236 ++++++ 13 files changed, 1868 insertions(+), 872 deletions(-) create mode 100644 Documentation/devicetree/bindings/display/bridge/anx6345.yaml delete mode 100644 drivers/gpu/drm/bridge/analogix-anx78xx.h create mode 100644 drivers/gpu/drm/bridge/analogix/analogix-anx6345.c rename drivers/gpu/drm/bridge/{ => analogix}/analogix-anx78xx.c (90%) create mode 100644 drivers/gpu/drm/bridge/analogix/analogix-anx78xx.h create mode 100644 drivers/gpu/drm/bridge/analogix/analogix-i2c-dptx.c create mode 100644 drivers/gpu/drm/bridge/analogix/analogix-i2c-dptx.h create mode 100644 drivers/gpu/drm/bridge/analogix/analogix-i2c-txcommon.h
