interconnect: qcom: x1e80100: Add missing ACV enable_mask

2024-02-04T21:36:06Z

The ACV BCM is voted using bitmasks. Add the proper mask for this target.

interconnect: qcom: sm8650: Use correct ACV enable_mask

2024-02-04T21:35:50Z

The ACV enable_mask is historically BIT(3), but it's BIT(0) on this target. Fix it.

interconnect: qcom: sm8550: Enable sync_state

2024-01-10T13:16:46Z

To ensure the interconnect votes are actually meaningful and in order to prevent holding all buses at FMAX, introduce the sync state callback.

interconnect: qcom: sc8180x: Mark CO0 BCM keepalive

2024-01-10T13:16:26Z

The CO0 BCM needs to be up at all times, otherwise some hardware (like the UFS controller) loses its connection to the rest of the SoC, resulting in a hang of the platform, accompanied by a spectacular logspam. Mark it as keepalive to prevent such cases.

interconnect: qcom: icc-rpm: Fix peak rate calculation

2023-12-06T15:00:42Z

Per the commit message of commit 'dd014803f260 ("interconnect: qcom: icc-rpm: Add AB/IB calculations coefficients")', the peak rate should be 100/ib_percent. But, in what looks like a typical typo, the numerator value is discarded in the calculation. Update the implementation to match the described intention.
