From 0c00c50b41a9a6ee83eb16fb5c6c22e5115391b8 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Tue, 24 Jul 2012 15:41:19 +0100 Subject: regmap: irq: Enable devices for runtime PM while handling interrupts Some devices need to have a runtime PM reference while handling interrupts to ensure that the register I/O is available. Support this with a flag in the chip.
