From e00b0ab86c79c4e82eb821ac6d6a3daef2e3e600 Mon Sep 17 00:00:00 2001 From: Mauro Carvalho Chehab Date: Fri, 1 May 2020 17:37:51 +0200 Subject: docs: add IRQ documentation at the core-api book There are 4 IRQ documentation files under Documentation/*.txt. Move them into a new directory (core-api/irq) and add a new index file for it. While here, use a title markup for the Debugging section of the irq-domain.rst file.
