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.
