This patch series introduces the framework for supporting the Data
Object Exchange (DOE) feature for PCIe endpoint devices. Please refer
to the documentation added in patch 4 for details on the feature and
implementation architecture.

The implementation provides a common framework for all PCIe endpoint
controllers, not specific to any particular SoC vendor.

This patch series is the non-RFC version of the RFC series at 
https://lore.kernel.org/all/20260213123603.420941-1-a-garg7@ti.com/

The changes since v1 are documented in the respective patch description.

A new patch (patch 3) have been introduced in the series. This patch
moves the burden of initializing and setting-up the DOE mailbox from
controller driver to EPC core driver, avoiding the duplication of code
across the controller drivers. This patch adds APIs to the EPC core
driver, which simply needs to be called by the controller driver during
probe/cleanup if it supports DOE capability.
