This bus has three USB-related devices attached to it: 0x25: Maxim 77759 Type-C port controller 0x35: Maxim 20339EWB Surge protection IC 0x36: Maxim 77759 Fuel gauge 0x57: NXP PCA9468 Battery charger 0x66: Maxim 77759 PMIC 0x69: Maxim 77759 Charger where the Maxim 77759 has multiple i2c slave addresses. These don't have (upstream) Linux drivers yet, but nevertheless we can enable the bus so as to allow working on them (and to make i2cdetect / i2cdump / etc. work).
