One reason for this is the difficulty some have had with setting flags
from DT bindings.

Could you elaborate on this? I've been adding flags to DT bindings for
this sort of thing, but it feels a bit like it's in that grey area of
not really describing the hardware itself. This information needs to
be specified somehow though.

It depends on the flag.  A good example is the CLK_DIVIDER_ONE_BASED
flag which does describe the hardware.  It informs the binding that
indexing starts at 1, not 0, which is a valid part of the hardware
description.

However flags that deal with software policy do not belong on DT.
CLK_SET_RATE_PARENT certainly does not belong in the DT binding since
this is a pure Linux-ism.  Every binding just needs to be reviewed on a
case-by-case basis to make sure the flags are related only to the
hardware.

So given the desire to eliminate platform code, is there a particular
way that these other flags can be specified instead of DT bindings?

Cheers
James
