From f6658c1c4ae98477d6be00495226c0617354fe76 Mon Sep 17 00:00:00 2001 From: Markus Schneider-Pargmann Date: Fri, 27 Jan 2023 16:44:43 +0100 Subject: [PATCH 11/42] thermal/drivers/mediatek: Control buffer enablement tweaks 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.
