I took the id now, for 6.0-final as it seems to be totally independant of the other commits (otherwise you would not have tagged it for the stable tree.) The remainder should probably be resent and send through the acpi tree. thanks, greg k-h

Okay. The last patch depends on that ID patch, so Rafael, you need to handle that conflict with immutable branch I guess. Or should we just skip that patch for now? I think another way to handle this would be that Greg, you take the whole series. thanks,

You can wait for -rc3 or so which should have that commit in it. thanks, greg k-h

Hi, The helper function returns all memory resources described for a device regardless of the ACPI descriptor type (as long as it's memory), but the first patch introduces new ACPI ID for the IOM controller on Intel Meteor Lake and also separately modifies the driver so that it can get the memory resource from Address Space Resource Descriptor. An alternative would have been to introduce that helper function first so we would not need to modify the driver when the new ID is added, but then the helper would also need to be applied to the stable kernel releases, and that does not feel necessary or appropriate in this case, at least not IMO. So that's why I'm proposing here that we first add the ID, and only after that introduce the helper, and only for mainline. That way the patch introducing the ID is the only that goes to the stable releases. If that's okay, and these don't have any other problems, I assume it's OK if Rafael takes all of these, including the ID? thanks, Heikki Krogerus (5): ACPI: resource: Filter out the non memory resources in is_memory() ACPI: resource: Add helper function acpi_dev_get_memory_resources() ACPI: APD: Use the helper acpi_dev_get_memory_resources() ACPI: LPSS: Use the helper acpi_dev_get_memory_resources() usb: typec: intel_pmc_mux: Use the helper acpi_dev_get_memory_resources() Utkarsh Patel (1): usb: typec: intel_pmc_mux: Add new ACPI ID for Meteor Lake IOM device drivers/acpi/acpi_apd.c | 9 +-------- drivers/acpi/acpi_lpss.c | 9 +-------- drivers/acpi/resource.c | 20 ++++++++++++++++++++ drivers/usb/typec/mux/intel_pmc_mux.c | 12 ++++-------- include/linux/acpi.h | 1 + 5 files changed, 27 insertions(+), 24 deletions(-)
