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. Signed-off-by: Rob Herring <robh@kernel.org>
