It was introduced by below commits: commit 0f153a1b8193ce768be4df0400aeb2c8f2a3b3da Author: Rob Herring <[email protected]> Date: Wed Dec 15 16:56:46 2021 -0600 usb: chipidea: Set the DT node on the child device The ChipIdea glue drivers just copy the glue resources to the "ci_hdrc" child device. Instead, set the child device's DT node pointer to the parent device's node so that platform_get_irq() can find the IRQ resources in the DT. This removes the need for statically populating the IRQ resources from the DT which has been deprecated for some time.
