[PATCH v4 0/2] Add reset control for mfd syscon devices

[Jeremy Kerr <jk@codeconstruct.com.au>]

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
