From 6054b9cae24f7ff09e502cea408dad140210681a Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Wed, 26 Sep 2012 19:03:51 +0200 Subject: [PATCH] pinctrl/nomadik: use simple or linear IRQ domain This alters the Nomadik pinctrl driver to: - Call irqdomain_add_linear() for the DT case so we get all independent from IRQ numbers in this case. - Call irqdomain_add_simple() for the legacy case, which allocates the IRQ descriptors for the Nomadik pin controller dynamically.
