I listed them so that there was a full picture of the feature implementation. The "pmdomain: ti_sci: handle wakeup constraint for out-of-band wakeup" patch has been merged already [1]. The "arm64: dts: ti: k3-am62: Support Main UART wakeup" series is posted [2] and has a dependency on this patch. Sorry for the confusion with the GitHub links, in the future I either won't add them or will add lore links instead.
