From 4c90aa94f6b3e33f57faaf19ef9819195dff61d3 Mon Sep 17 00:00:00 2001 From: Mark Brown Date: Fri, 26 Nov 2010 17:19:34 +0000 Subject: mfd: Provide pm_runtime_no_callbacks flag in cell data Allow MFD cells to have pm_runtime_no_callbacks() called on them during registration. This causes the runtime PM framework to ignore them, allowing use of runtime PM to suspend the device as a whole even if not all drivers for the MFD can usefully implement runtime PM. For example, RTCs are likely to run continuously regardless of the power state of the system.
