Subject[PATCH 0/2] Add new reg_update_bits() support
Date
The Spreadtrum platform uses a special set/clear method to update
registers' bits, thus this patch set registers a physical regmap
bus into syscon core to support this feature instead of using the
MMIO bus, which is not a physical regmap bus.

Any comments are welcome. Thanks.

Changes from RFC v2:
- Drop regmap change, which was applied by Mark.
- Add more information about how to use set/clear.
- Add checking to ensure the platform is compatible with
using a new physical regmap bus.

Changes from RFC v1:
- Add new helper to registers a physical regmap bus instead of
using the MMIO bus.
