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
--- Jeremy Kerr (2): dt-bindings: mfd/syscon: Add resets property mfd: syscon: allow reset control for syscon devices
