Re: [PATCH v2 3/4] thermal: mediatek: control buffer enablement tweaks

From: Markus Schneider-Pargmann <msp@baylibre.com>

Add logic in order to be able to turn on the control buffer on MT8365.
This change now allows to have control buffer support for MTK_THERMAL_V1,
and it allows to define the register offset, and mask used to enable it.
