That's strange. The patch series was sent with your address <jassisinghbrar@xxxxxxxxx> on "To:" field. And that can be seen on patch archive [1]. > 2) Shouldn't this patch be broken into a fix and an enablement patch? MSM8939 is the only platform that I know has multiple clusters and uses APCS driver. So the change becomes a fix only when MSM8939 is enabled. But if you prefer to separate the change, I will do so. Shawn [1] https://lore.kernel.org/patchwork/patch/1420808/
