Subject: [RFC PATCH v2 0/3] Add new reg_update_bits() support
Date:   Mon, 13 Apr 2020 14:13:18 +0800

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

  mfd: syscon: Support physical regmap bus
  regmap: Add bus reg_update_bits() support
  soc: sprd: Add Spreadtrum special bits updating support
