Subject: [PATCH] usb: chipidea: Set the DT node on the child device
Date: Wed, 15 Dec 2021 16:56:46 -0600 [thread overview]
Message-ID: <20211215225646.1997946-1-robh@kernel.org> (raw)
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.
