Patch 1 enables the second USB 2.0 host controller, which serves the USB lines of the B-key slot. Patch 2 describes the power, reset and W_DISABLE# controls of the slot. Patch 3 adds the PWM fan and ties it to the CPU thermal zone. Pin assignments were checked against the ROCK 3B V1.51 schematic. Tested on a ROCK 3B with a SIMCom SIM7600G-H module and a 5V fan, running Linux 6.12 (OpenWrt) with the same changes applied.
