This RFC series adds a facility for syscon devices to control a reset
line when probed; we have instances of simple register-only syscon
resources that need deassertion of a reset line for the register set to
be accessible.
Rather than requiring a specific driver to implement this, it'd be nice
to use the generic syscon device and the generic resets linkage to do
so.
Any comments/queries/etc are most welcome.
Cheers,
Jeremy

v2:
- use direct syscon registration interface, rather than the (unused)
syscon platform device code
- consequently, add regmap infrastructure to attach a reset
controller, in a similar way to attaching clocks
v3:
- drop regmap reset control and just do a direct deassert from the syscon
driver
v4:
- collapse unnecessary else block in syscon driver reset control
