@Jesse Sung The following is the response from the feature owner 1. This patch doesn’t change the functionality on the usb-dw3 for EHL, it mainly renames the PCI device define to ensure no misunderstanding on there’s an LP (low power version) available.
2. As for the effect on changing this, EHL will allow the PM runtime & other logic within dwc3 to use the ACPI DSM to put the IP into low power, as it depends on the specific PMU registers programming to truly set it to low power. Meanwhile, the other dwc3-pci functionality remains unaffected. I prefer to merge it into your kernel tree and it can run into low power mode if the platform has the capability. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux-intel in Ubuntu. https://bugs.launchpad.net/bugs/1929902 Title: [EHL] enable USB-dw3 Status in intel: New Status in linux package in Ubuntu: New Status in linux-intel package in Ubuntu: In Progress Bug description: Description Enable USB-dw3 for Elkhart Lake Hardware: Elkhart Lake Target Release: 21.04 Target Kernel: TBD External links: https://github.com/intel/linux-intel-quilt/tree/mainline-tracking-v5.11-yocto-210223T083754Z To manage notifications about this bug go to: https://bugs.launchpad.net/intel/+bug/1929902/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : [email protected] Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
