[PATCH v2 0/3] Add Intel Input Output Manager driver

[Rajmohan Mani]

Hi,

This patch series add support for Intel Input Output Manager (IOM)
driver, which is leveraged by the Intel PMC USB mux control driver.

changes from v1:
- Included device role (UFP) support patch from Heikki to this series.
- Addressed Greg's comments on v1 with below changes
- Used per-instance variable for struct intel_iom
- Removed struct device *dev inside probe function
- Removed dev_set_drvdata() inside probe function
- Added NULL pointer check on struct intel_iom * as well as members
  dev and regbar, inside intel_iom_port_status(), to protect against
  calls to this API before driver gets probed.
- Limit support to only one IOM device
- Removed intel_iom_get()/intel_iom_put() calls, as the dependency through
  Kconfig is enough to prevent the IOM driver from unloading, when used
  by callers.
