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.
