Subject: [PATCH v2 0/4] add PMCI driver support
Date: Thu, 16 Jun 2022 22:04:01 -0400	[thread overview]
Message-ID: <20220617020405.128352-1-tianfei.zhang@intel.com> (raw)

PMCI(Platform Management Control Interface) is a software-visible
interface, connected to card BMC which provided telemetry and mailbox
functionalities for Intel PAC FPGA card.

Currently, intel-m10-bmc driver support Intel MAX10 BMC functions via
SPI interface. To support multiple bus interfaces, splits the common
code from intel-m10-bmc driver into intel-m10-bmc-core. On the other
hand, it 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: split the common code from intel-m10-bmc driver into
intel-m10-bmc-core.
patch 3: add a driver for PMCI.
patch 4: introduce a new data structure m10bmc_csr for the different
register definition of MAX10 CSRs.

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
