PMCI(Platform Management Control Interface) is a software-visible
interface, connected to card BMC which provided basic register
access functionality from host to Card BMC. This pmci-bmc driver
leverages the regmap APIs to support Intel specific Indirect
Register Interface for register read/write on PMCI driver. 

This patchset adding a driver for the PMCI-base interface of Intel
MAX10 BMC controller.

patch 1: use ddata for local variables which directly interacts with
dev_get_drvdata()/dev_set_drvdata().
patch 2: add a driver for PMCI.
patch 3: introduce a new member in intel_m10bmc for the different
base register address of MAX10 CSRs.

v3:
  - create a new intel-m10-bmc-pmci driver, and discard the bmc-core
    file which adds in v2.
  - create a new file for sysfs-driver-intel-m10-bmc-pmci ABI.
  - remove the regmap_access_table
  - introduce a new member "base" in intel_m10bmc for different base
    register address.
  - rebased on 5.19-rc3
v2:
  - use regmap APIs to support Intel specific Indirect Register Interface
    on PMCI driver.
  - fix compile warning reported by lkp.
  - rebased on 5.19-rc2

Tianfei Zhang (3):
  mfd: intel-m10-bmc: rename the local variables
  mfd: intel-m10-bmc: add PMCI driver
  mfd: intel-m10-bmc: support different BMC base register address
