From 124e1b1d0924ca51ded8bb6f52844b2bc9e485f7 Mon Sep 17 00:00:00 2001 From: Srinivas Pandruvada Date: Thu, 8 May 2014 22:58:00 +0100 Subject: [PATCH] iio: accel: kxcjk-1013: support runtime pm In an effort to improve raw read performance and at the same time enter low power state at every possible chance. For raw reads, it will keep the system powered on for a default or user specified time, via autosuspend_delay attribute of device power. This will help read multiple samples without power on/off sequence. For triggers it will keep the system on till, requested to be turned off by trigger state by utilizing run time PM usage counters. When runtime pm is not enabled, then it keeps the chip in operation mode always. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jonathan Cameron --- Reading git-format-patch failed
