| gpio_reset_req_n | |||
| gpio_cp_reset | cp baseband processor | ||

| gpio_cp_dump_int | cp == baseband processor | ||
| gpio_flm_uart_sel | Galaxy Nexus | Not used in libsamsung-ipc for other Replicant compatible devices | Modem download mode ? |
| gpio_cp_warm_reset | |||
| gpio_revers_bias_clear | |||
| gpio_revers_bias_restore | |||
| gpio_sim_detect | Detect SIM card presence ? |
Do we really want to check the SIM card presence?
Would it be possible not to for privacy reasons?
