2024-10-22interconnect: Switch back to struct platform_driver::remove()Uwe Kleine-König
After commit 0edb555a65d1 ("platform: Make platform_driver::remove() return void") .remove() is (again) the right callback to implement for platform drivers. Convert all platform drivers below drivers/interconnect to use .remove(), with the eventual goal to drop struct platform_driver::remove_new(). As .remove() and .remove_new() have the same prototypes, conversion is done by just changing the structure member name in the driver initializer.

2024-02-26interconnect: constify of_phandle_args in xlateKrzysztof Kozlowski
The xlate callbacks are supposed to translate of_phandle_args to proper provider without modifying the of_phandle_args. Make the argument pointer to const for code safety and readability.

2024-01-31interconnect: qcom: x1e80100: Remove bogus per-RSC BCMs and nodesKonrad Dybcio
The downstream kernel has infrastructure for passing votes from different interconnect nodes onto different RPMh RSCs. This neither implemented, not is going to be implemented upstream (in favor of a different solution using ICC tags through the same node). Unfortunately, as it happens, meaningless (in the upstream context) parts of the vendor driver were copied, ending up causing havoc - since all "per-RSC" (in quotes because they all point to the main APPS one) BCMs defined within the driver overwrite the value in RPMh on every aggregation. To both avoid keeping bogus code around and possibly introducing impossible-to-track-down bugs (busses shutting down for no reason), get rid of the duplicated BCMs and their associated ICC nodes.
