Subject[PATCH v3 3/3] mfd: intel-m10-bmc: support different BMC base register address
Date
There are different base addresses for the MAX10 CSR registers.
Introducing a new member "base" in intel_m10bmc data structure
to support different BMC base register addresses.

Signed-off-by: Tianfei Zhang <tianfei.zhang@intel.com>
---
v3:
- use a new member "base" instead of m10bmc_csr data structure.
