Struct Config 

#[non_exhaustive]
pub struct Config {
    pub lanes: LaneCount,

CSI-2 Host configuration.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

lanes: LaneCount

Number of data lanes in use.

data_rate_mbps: u32

Nominal data rate per lane in Mbps. Used to look up the D-PHY band table (PFCR.HSFR + the Synopsys oscillator target).

virtual_channels: u8

Virtual channels to start together as one stream. Bit n enables VC n (0..=3). Defaults to 0b0001 (VC0 only).

config_clock_mhz: u32

Configuration-clock frequency in MHz feeding the D-PHY test/control interface. Recorded but unused — the BSP-correct CCFR value is hard-coded to 0x28 (matches the Synopsys D-PHY reference) so this field is not driven into the register today.

hs_freq_range_override: Option<u8>

Override for the D-PHY high-speed frequency-range band (PFCR.HSFR, 7 bits). None looks up the band from data_rate_mbps.

data_type_format: u8

VCxCFGR1.CDTFT — common data-type format for every enabled VC. Encodes the bits-per-pixel of the incoming stream: 0=6, 1=7, 2=8, 3=10, 4=12, 5=14, 6=16. Defaults to 3 (RAW10), the most common Bayer sensor format.

Implementations

impl Config

pub const fn new(lanes: LaneCount, data_rate_mbps: u32) -> Self

Create a configuration with the given lane count and per-lane data rate. Defaults: VC0 only, 24 MHz config clock, HSFR auto-derived, 10 bits-per-pixel (RAW10).
