Enumeration Type Documentation

aiclk_arb_max

enum aiclk_arb_max

AICLK maximum frequency arbiters.

These arbiters set upper limits on the AICLK frequency. The effective maximum frequency is determined by the lowest enabled arbiter value.

Warning

The order of these enum values must be preserved for compatibility.

aiclk_arb_max_doppler_slow	Doppler slow throttling limit
aiclk_arb_max_doppler_critical	Doppler critical throttling limit
aiclk_arb_max_count	Number of max arbiters

aiclk_arb_min

enum aiclk_arb_min

AICLK minimum frequency arbiters.

These arbiters set lower limits on the AICLK frequency. The effective minimum frequency is determined by the highest enabled arbiter value.

Warning

The order of these enum values must be preserved for compatibility.
