[PATCH v9 2/5] thermal: mediatek: control buffer enablement tweaks

[PATCH v9 2/5] thermal: mediatek: control buffer enablement tweaks
Posted by Amjad Ouled-Ameur 3 years ago 
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.

This change conflicts with commit 4f2ee0aa2e706

I fixed it with:

-       if (mt->conf->version != MTK_THERMAL_V1) {
-               mtk_thermal_turn_on_buffer(apmixed_base);
+       mtk_thermal_turn_on_buffer(apmixed_base);
+
+       if (mt->conf->version != MTK_THERMAL_V1)
                 mtk_thermal_release_periodic_ts(mt, auxadc_base);
-       }

Let me know if there is something wrong.

This should rather be "mtk_thermal_turn_on_buffer(mt, apmixed_base);" as this patch

also adds mtk_thermal arg to the function.

I think it's rather MTK_THERMAL_V2 and not MTK_THERMAL_V1. Other than that, it looks

fine by me, thanks.

It was before if (version == MTK_THERMAL_V2). Now there is a V3, so it 
is replaced by if (version != MTK_THERMAL_V1) in order to include the V3
