[PATCH v13 1/6] thermal: drivers: mediatek: Relocate driver to mediatek folder
Posted by bchihi@baylibre.com 1 year, 9 months ago 
From: Balsam CHIHI <bchihi@baylibre.com>

Add MediaTek proprietary folder to upstream more thermal zone and cooler
drivers, relocate the original thermal controller driver to it, and rename it
as "auxadc_thermal.c" to show its purpose more clearly.
