interconnect: qcom: msm8996: add missing link to SLAVE_USB_HS

2026-01-11T14:18:21+00:00

[ Upstream commit 8cf9b43f6b4d90e19a9341edefdd46842d4adb55 ] >From the initial submission the interconnect driver missed the link from SNOC_PNOC to the USB 2 configuration space. Add missing link in order to let the platform configure and utilize this path.

interconnect: qcom: sc8180x: Mark CO0 BCM keepalive

[ 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.

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.
