* drm/amd/display: eliminate long wait between register polls on MaximusKen Chalmers2018-08-271-7/+2Star
| | | | | | | | | | | | | | | | | | | | | | [Why] Now that we "scale" time delays correctly on Maximus (as of diags svn r170115), the forced "35 ms" wait time now becomes 35 ms * 500 = 17.5 seconds, which is far too long. Even having to repeat polling a register once causes excessive delays on Maximus. [How] Just use the regular wait time passed to the generic_reg_wait() function. This is sufficient for Maximus now, and it also means that there's one less "Maximus-only" code path in DAL. Also disable the "REG_WAIT taking a while:" message on Maximus, since things do take a while longer there and 1-2ms delays are not uncommon (and nothing to worry about).
