[PATCH 1/6] drivers: thermal: tsens: load regmap from phandle for 8960

From: Ansuel Smith
Date: Thu Jul 09 2020 - 17:52:14 EST


Devices based on 8060 tsens driver (ipq8064) use the reg of the gcc
driver. Permit to load the regmap from a syscon phandle instead of fail
as the reg are already used by another driver.
