# Regex patterns for parsing more general platform-specific identifiers from FW versions.
# - Part number: Toyota part number (usually last character needs to be ignored to find a match).
# Each ECU address has just one part number.
# - Platform: usually multiple codes per an openpilot platform, however this is the least variable and
# is usually shared across ECUs and model years signifying this describes something about the specific platform.
# This describes more generational changes (TSS-P vs TSS2), or manufacture region.
# - Major version: second least variable part of the FW version. Seen splitting cars by model year/API such as
# RAV4 2022/2023 and Avalon. Used to differentiate cars where API has changed slightly, but is not a generational change.
# It is important to note that these aren't always consecutive, for example:
# Avalon 2016-18's fwdCamera has these major versions: 01, 03 while 2019 has: 02
# - Sub version: exclusive to major version, but shared with other cars. Should only be used for further filtering.
# Seen bumped in TSB FW updates, and describes other minor differences.

# - fwdCamera: describes actual features related to ADAS. For example, on the Avalon it describes
# when TSS-P became standard, whether the car supports stop and go, and whether it's TSS2.
# On the RAV4, it describes the move to the radar doing ACC, and the use of LTA for lane keeping.
# Note that the platform codes & major versions do not describe features in plain text, only with
# matching against other seen FW versions in the database they can describe features.
# - fwdRadar: sanity check against fwdCamera, commonly shares a platform code.
# For example the RAV4 2022's new radar architecture is shown for both with platform code.
# - abs: differentiates hybrid/ICE on most cars (Corolla TSS2 is an exception, not used due to hybrid platform combination)
# - eps: describes lateral API changes for the EPS, such as using LTA for lane keeping and rejecting LKA messages
