interconnect: qcom: sc8180x: Mark CO0 BCM keepalive

2024-02-23T08:12:34+00:00

[ 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.

Revert "interconnect: qcom: sm8250: Enable sync_state"

2024-01-10T16:10:37+00:00

This reverts commit 3637f6bdfe2ccd53c493836b6e43c9a73e4513b3 which is commit bfc7db1cb94ad664546d70212699f8cc6c539e8c upstream. This resulted in boot regression on RB5 (sm8250), causing the device to hard crash into USB crash dump mode everytime.

interconnect: Treat xlate() returning NULL node as an error

2024-01-01T12:39:00+00:00

[ Upstream commit ad2ab1297d0c80899125a842bb7a078abfe1e6ce ] Currently, if provider->xlate() or provider->xlate_extended() "successfully" return a NULL node, then of_icc_get_from_provider() won't consider that an error and will successfully return the NULL node. This bypasses error handling in of_icc_get_by_index() and leads to NULL dereferences in path_find(). This could be avoided by ensuring provider callbacks always return an error for NULL nodes, but it's better to explicitly protect against this in the common framework.
