Re: [PATCH v7 08/10] PCI: dw-rockchip: Set broken L1SS resume flag

[sashiko-bot@kernel.org]

> During system suspend, the Rockchip RC driver effectively powers off the
> controller. If the link is in L1SS and the endpoint asserts CLKREQ# to
> exit L1SS, the time required to wake the system and restore the
> PHY/REFCLK may exceed the L1SS exit timing (L10_REFCLK_ON +
> T_COMMONMODE), resulting in Link Down (LDn) and a reset of the endpoint.
> Set broken_l1ss_resume flag to indicate this limitation to the PCIe
> framework. This results in pci_suspend_retains_context() returning false
> and PCIe client can avoid relying on device state being preserved
> during system suspend.
