If you say yes here you get support the RTC MFD driver for Sophgo
CV1800 series SoC. The RTC module comprises a 32kHz oscillator,
Power-on-Reset (PoR) sub-module, HW state machine to control chip
power-on, power-off and reset. Furthermore, the 8051 subsystem is
located within RTCSYS including associated SRAM block.
This driver can also be built as a module. If so, the module will be
called cv1800-rtcsys.
