PS2, Line 21: .speed_config[0] = {
            : 				.speed = I2C_SPEED_FAST,
            : 				.scl_lcnt = 190,
            : 				.scl_hcnt = 100,
            : 				.sda_hold = 40,
            : 			}
The recommendation is to configure the measured rise_time_ns and fall_time_ns here instead of scl_lcnt and scl_hcnt. Use these lcnt/hcnt values, measure the rise_time_ns and fall_time_ns using the scope and add those measured values here.

Prefer to split this CL into 4 parts
1) Thermal and DPTF configuration
2) Audio Configuration
3) Trackpad configuration
4) USB Camera configuration

That way it will be easy to review.
