From 84a76694bc17dd31eed84ab2fae857f18909da42 Mon Sep 17 00:00:00 2001 From: Brian Masney Date: Tue, 17 Jan 2017 04:25:00 -0500 Subject: [PATCH] staging: iio: isl29028: only set proximity sampling rate when proximity is enabled isl29028_chip_init_and_power_on() calls isl29028_set_proxim_sampling() and this is not needed until the user actually needs to take a proximity reading. This patch moves the isl29028_set_proxim_sampling() call from isl29028_chip_init_and_power_on() to isl29028_enable_proximity(). This sets the stage for faster resume times from the runtime power management if the user is only querying the ALS/IR sensor.
