Subject: dwc3: core: added an API to invoke irq handlers
X-Git-Url: http://git.dujemihanovic.xyz/?a=commitdiff_plain;h=27d3b89d3362c912dccf1d9d27bcefc1e361fe19;p=u-boot.git

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.
