From 8b5163eb988067093064ecb10265da27fd000cad Mon Sep 17 00:00:00 2001 From: Max Filippov Date: Mon, 13 Aug 2018 18:21:08 -0700 Subject: xtensa: drop variant IRQ support If an xtensa core provides an additional IRQ controller it should be treated as a separate piece of hardware and be driven by an irqchip driver.
