From ce1d37cb7697abcc3d892558acd33a1333596534 Mon Sep 17 00:00:00 2001 From: Lad Prabhakar Date: Mon, 20 Dec 2021 01:04:11 +0000 Subject: usb: musb: dsps: Use platform_get_irq_byname() to get the interrupt platform_get_resource_byname(pdev, IORESOURCE_IRQ, ..) relies on static allocation of IRQ resources in DT core code, this causes an issue when using hierarchical interrupt domains using "interrupts" property in the node as this bypasses the hierarchical setup and messes up the irq chaining. In preparation for removal of static setup of IRQ resource from DT core code use platform_get_irq_byname().
