* The :kconfig:option:`CONFIG_MODEM_GSM_PPP` modem driver is obsolete.
Instead the new :kconfig:option:`CONFIG_MODEM_CELLULAR` driver should be used.
As part of this :kconfig:option:`CONFIG_GSM_MUX` and :kconfig:option:`CONFIG_UART_MUX` are being
marked as deprecated as well. The new modem subsystem :kconfig:option:`CONFIG_MODEM_CMUX`
and :kconfig:option:`CONFIG_MODEM_PPP`` should be used instead.
