[PATCH V3 00/11] i3c: mipi-i3c-hci-pci: Define Multi-Bus Instances for Intel controllers

[Adrian Hunter]

Hi


Changes in V3:

  A notable change in V3 is the introduction of patch 6 "Assign unique
  device names and IDs for Intel LPSS I3C" which does away with dynamic
  devid allocaion.

    i3c: mipi-i3c-hci: Quieten initialization messages
	Minor white space tweaks to fix alignment

    i3c: mipi-i3c-hci-pci: Enable MSI support
	Enhance commit message

    i3c: mipi-i3c-hci-pci: Assign unique device names and IDs for Intel LPSS I3C
	New patch

    i3c: mipi-i3c-hci: Allow for Multi-Bus Instances
	Enhance commit message

    i3c: mipi-i3c-hci-pci: Pass base regs as platform data to i3c core device
	Enhance commit message

    i3c: mipi-i3c-hci-pci: Convert to MFD driver
	Add Frank's Rev'd-by
	Adjust for doing away with dynamic devid allocation

    i3c: mipi-i3c-hci-pci: Add support for Multi-Bus Instances
	Make hci a parameter of mipi_i3c_hci_pci_alloc()
	Adjust for doing away with dynamic devid allocation
	Enhance commit message

    i3c: mipi-i3c-hci-pci: Define Multi-Bus instances for supported controllers
	Adjust for doing away with dynamic devid allocation

Changes in V2:
	Add Frank's Rev'd-by for patches 1 - 3
	Drop default driver data
	New patches split from "i3c: mipi-i3c-hci-pci: Add support for
	Multi-Bus Instances"
	Conversion to MFD split into separate patch
	Simplify ID allocation / free
	Correct use of __free()
	Also define instance 0 in driver_data


Add support for MIPI I3C Host Controllers with the Multi-Bus Instance
capability.  These controllers can host multiple I3C buses (up to 15)
within a single hardware function (e.g., PCIe B/D/F), providing one
indepedent HCI register set and corresponding I3C bus controller logic
per bus.

Add support for that to mipi-i3c-hci-pci and mipi-i3c-hci and define
Multi-Bus Instances for Intel controllers.

There are also some tidy-up patches to start with.
