Subject: [PATCH v14 0/7] soc: mediatek: SVS: introduce MTK SVS
Date: Thu, 25 Mar 2021 10:51:07 +0800 [thread overview]
Message-ID: <20210325025114.25842-1-roger.lu@mediatek.com> (raw)
1. SVS driver uses OPP adjust event in [1] to update OPP table voltage part.
2. SVS driver gets thermal/GPU device by node [2][3] and CPU device by get_cpu_device(). After retrieving subsys device, SVS driver does
device_link_add() to make sure probe/suspend callback priority.
3. SVS dts refers to reset controller [4] to help reset SVS HW.

[4] https://patchwork.kernel.org/project/linux-mediatek/patch/20200817030324.5690-5-crystal.guo@mediatek.com/
changes since v13:
- Fix "mtk-svs.yaml: properties:nvmem-cells:maxItems: False schema does not allow 2"
- Remove wrong maintainer "Nishanth Menon <nm@ti.com>"
- When turn_pt = 0, SVS HIGH bank fills FREQPCT74 / FREQPCT30 with 0 and SVS controller won't run normally. Therefore, we initialize SVS HIGH bank's FREQPCT30 with svsb->freqs_pct[0] to avoid this issue.
- Change SVS GPU opp count back from 14 to 16 because GPU DVFS has a better solution
