Subject: [PATCH v2 00/10] PCI: endpoint: Make host reboot handling more robust
Date: Mon, 01 Apr 2024 21:20:26 +0530	[thread overview]
Message-ID: <20240401-pci-epf-rework-v2-0-970dbe90b99d@linaro.org> (raw)

Hello,

This is the follow up series of [1], to improve the handling of host reboot in
the endpoint subsystem. This involves refining the PERST# and Link Down event
handling in both the controller and function drivers.

Testing
=======

This series is tested on Qcom SM8450 based development board with both MHI_EPF
and EPF_TEST function drivers.

Dependency
==========

This series depends on [1] and [2].

- Mani
