From df8f13476443b70608c64b3e91f3876a06fa739c Mon Sep 17 00:00:00 2001 From: Eduardo Valentin Date: Sun, 15 Sep 2013 15:21:51 -0400 Subject: drivers: thermal: allow ti-soc-thermal run without pcb zone This patch changes the behavior of TI SoC thermal driver when there is a PCB thermal zone. Instead of reporting an error code when reading from PCB temperature sensor fails, this patch will make the driver attempt to compose the hotspot extrapolation based on bandgap readings only.
