Subject: [PATCH v2 1/4] thermal/core: Rename passive_delay and polling_delay with units
Date: Mon, 7 Dec 2020 20:08:59 +0100 [thread overview]
Message-ID: <20201207190902.30464-1-daniel.lezcano@linaro.org> (raw)
The input unit used by the thermal framework is the msec but it uses
the jiffies to set the timers.
As it is stored in the thermal zone device structure, everytime the
timer is setup at each polling interval, the msecs to jiffies
conversion happens. The jiffies is the unit the thermal framework is
using, so keeping it under the jiffies instead of msecs will save some
pointless conversion.
Set the scene to directly store the delays under their jiffies
form by adding to the variable name the 'ms' suffix.
