Hi,
this patchset adds DT binding docs and a drm_bridge driver for the Toshiba TC358767 eDP bridge, currently supporting only 24-bit DPI input and control via I2C. The chip is also capable to act as a DSI sink, but the driver doesn't support that yet. It is based on Andrey's initial driver, which can be found at https://github.com/CogentEmbedded/linux-zodiac.git, commit 4abb1d0a9a1c ("drm/i2c: tc358767 eDP encoder initial commit"). I have turned it into a drm_bridge driver and changed it to use regmap and the drm_dp helpers.
Changes since v1: - Explicitly describe DSI and DPI input ports in device tree, this moves DPI input to port@1 and eDP/DP output to port@2. - Replaced the regmap_read_poll_timeout macro with a function. - Rebased on top of SiI902x driver merge to avoid Makefile/Kconfig conflicts. - Fixed tc_pxl_pll_en: removed unnecessary checks, whitespace and comment improvements. - Switched to atomic connector funcs.
regards Philipp
