capabilities.h File Reference

Detailed Description

Declarative driver capabilities + channel-request types for the Channel Manager's predicate / dependency-resolution system (#3186).

Drivers publish:

• DriverCapabilities — small constant header (driver-wide facts)
• fl::span<const PinGroup> — per-hardware-resource enumeration

The Channel Manager (and unit tests) consume these via the free fl::canMatch / fl::canMatchBulk functions (declared in can_match.h), which return a HandleResult describing whether a single-pin or bulk ChannelRequest can be served by the supplied capability data.

This header defines pure POD data types only. No driver instance is required to use any of these.

Definition in file capabilities.h.

Classes
struct	fl::ChannelRequest
struct	fl::ChipsetClocklessTiming
struct	fl::ClocklessTimingCapability
struct	fl::DriverCapabilities
struct	fl::DriverCapabilities::Flags
	Peripheral-flavor flags. Default zero = neutral / no claim. More...
struct	fl::FreqRange
struct	fl::NanosRange
struct	fl::PinGroup
struct	fl::PinSet

Namespaces
namespace	fl
	Base definition for an LED controller.

Typedefs
using	fl::PinBitset = fl::bitset_fixed<kPinSetCapacity>

Enumerations
enum class	fl::HandleResult : fl::u8 {   fl::Yes = 0 , fl::NoProtocol = 1 , fl::NoPin = 2 , fl::NoPinPair = 3 ,   fl::NoFrequency = 4 , fl::NoTiming = 5 , fl::NoCapacity = 6 }
enum class	fl::PinSetKind : fl::u8 { fl::None = 0 , fl::AnyOutputPin = 1 , fl::Allowlist = 2 }
enum class	fl::Protocol : fl::u8 { fl::Clockless = 0 , fl::Spi = 1 }

Functions
constexpr bool	fl::isYes (HandleResult r) FL_NO_EXCEPT
	Convenience: most call sites really want a bool.

Variables
static constexpr fl::u32	fl::kPinSetCapacity = 128u
	Maximum pin number representable in a PinSet's bitset.
