The chip can be found in Qualcomm RB5 platform [1], [2]. [1] https://www.qualcomm.com/products/qualcomm-robotics-rb5-platform [2] https://www.thundercomm.com/app_en/product/1590131656070623 Changes since v3: - Support for firmware upgrades - Simplified modes table to include only used fields (w, h, refresh) - Added more entries to display modes table, as more modes are supported by the firmware - Wait for EDID to be available from the hardware before reading it - Do not store EDID in the interim buffer, lowering the size of per-device struct Changes since v2: - Squashed connector support into main patch - Added comment on modes table - Dropped display timings support, covered by EDID - Dropped sleep mode support - Dropped hpd_status reading from ISR handler - Added "sentinel" comments to empty table entries Changes since v1: - Fix whitespaces/indentation - Support working without DRM_BRIDGE_ATTACH_NO_CONNECTOR
