Yes, let's make the meanings of the bit fields clear...

--- ptp_clock.h ---

/*
 * Bits of the ptp_extts_request.flags field:
 */
#define PTP_ENABLE_FEATURE      BIT(0)
#define PTP_RISING_EDGE         BIT(1)
#define PTP_FALLING_EDGE        BIT(2)
#define PTP_EXTTS_VALID_FLAGS   (PTP_ENABLE_FEATURE | \
                                 PTP_RISING_EDGE | \
                                 PTP_FALLING_EDGE)

/*
 * Bits of the ptp_perout_request.flags field:
 */
#define PTP_PEROUT_ONE_SHOT     BIT(0)
#define PTP_PEROUT_VALID_FLAGS  (PTP_PEROUT_ONE_SHOT)

struct ptp_extts_request {
        unsigned int flags;  /* Bit field of PTP_EXTTS_VALID_FLAGS. */
};

struct ptp_perout_request {
        unsigned int flags;  /* Bit field of PTP_PEROUT_VALID_FLAGS. */
};


Thanks,
