Subject: Re: [PATCH v1] PCI: dwc: Add force_l2 flag for platforms requiring L2 entry without D3cold
Date: Mon, 06 Jul 2026 02:56:36 +0000 [thread overview]

> Some platforms like i.MX have their PCIe RC controllers powered off
> during system suspend, requiring full re-initialization on resume.
> These platforms need to enter L2 state to properly notify endpoints
> before power loss, even when D3cold is not supported.
>
> Add a force_l2 flag to allow platform drivers to request L2 entry
> during suspend regardless of D3cold capability, and enable it for
> i.MX PCIe controllers.
