808 | * The MODEM device requires its RESET# pin kept high during probe. |
809 | * That requirement can be fulfilled in several ways: | |
810 | * - with a descriptor of already functional modem_nreset regulator | |
811 | * assigned to the MODEM private data, | |
812 | * - with the regulator not yet controlled by modem_pm function but | |
813 | * already enabled by default on probe, | |
814 | * - before the modem_nreset regulator is probed, with the pin already | |
815 | * set high explicitly. | |
816 | * The last one is already guaranteed by ams_delta_latch2_init() called | |
817 | * from machine_init. | |
818 | * In order to avoid taking over ttyS0 device slot, the MODEM device | |
819 | * should be registered after OMAP serial ports. Since those ports | |
820 | * are registered at arch_initcall, this function can be called safely | |
821 | * at arch_initcall_sync earliest. | |
