CVS DEVICE QUIRK FLAGS(9)

💖 CVS device quirk flags 💖

okay bestie, welcome to CVS device quirk flags(9) — this is the page for the bit flag macros that describe per-device behavioral adjustments. They get applied after VID/PID matching (see cvs_i2c_check and cvs_apply_quirks), and they let the driver selectively alter logic paths for firmware / hardware variants without introducing hard-coded conditionals at each call site. it’s giving “small flags, big main character energy” ✨

here’s the flag lore, one iconic little macro at a time:

• ICVS_NO_MIPI_CONFIG — device firmware performs its own MIPI link setup, so skip sending HOST_SET_MIPI_CONFIG.
• ICVS_SKIP_FW_RESET — skip issuing a post firmware-update reset sequence.
• ICVS_NO_CAPS — device firmware does not support GET_DEV_CAPABILITY; skip the capability query and treat caps as unsupported.
• ICVS_FW_BUF_SIZE_256 — firmware expects chunk transfer buffer size of 256 bytes (override defaults if they differ).
• ICVS_FW_HEADER_SIZE_256 — firmware header size fixed at 256 bytes offset for start of payload data.
• ICVS_HOST_SENSOR_PWR_CTRL — host must control sensor power sequencing.
• ICVS_HOST_PRIV_CTRL — host owns privacy LED gating.
• ICVS_HOST_VISION_SENSING — host enables vision sensing capability bit.
• ICVS_NO_FW_UPDATE — device does not support firmware update.
