From 27d3b89d3362c912dccf1d9d27bcefc1e361fe19 Mon Sep 17 00:00:00 2001 From: Kishon Vijay Abraham I Date: Mon, 23 Feb 2015 18:40:06 +0530 Subject: dwc3: core: added an API to invoke irq handlers Since interrupt support is not present in u-boot, added an API to handle the interrupts in dwc3 core. This API can be polled to handle the interrupts.
