8 * claimed by sata-nv.c.
11 * Variable system clock when/if it makes sense
12 * Power management on ports

31 * timing_setup - shared timing computation and load
32 * @ap: ATA port being set up
33 * @adev: drive being configured
34 * @offset: port offset
35 * @speed: target speed
36 * @clock: clock multiplier (number of times 33MHz for this part)
38 * Perform the actual timing set up for Nvidia or AMD PATA devices.
39 * The actual devices vary so they all call into this helper function
40 * providing the clock multipler and offset (because AMD and Nvidia put
41 * the ports at different locations).
