interconnect: qcom: sm8550: Enable sync_state

2024-02-23T08:51:32Z

[ Upstream commit 24406f6794aa631516241deb9e19de333d6a0600 ] 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

2024-02-23T08:51:32Z

[ Upstream commit 85e985a4f46e462a37f1875cb74ed380e7c0c2e0 ] 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.

Add the generic icc sync_state callback to ensure interconnect votes are taken into account, instead of being pegged at maximum values.

interconnect: qcom: Convert to platform remove callback returning void

2023-10-18T10:37:39Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is ignored (apart from emitting a warning) and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Eventually after all drivers are converted, .remove_new() will be renamed to .remove(). Several drivers use qcom_icc_rpmh_remove() as remove callback which returns zero unconditionally. Make it return void and use .remove_new in the drivers. There is no change in behaviour.
