^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  1) * Ricoh RN5T567/RN5T618 PMIC
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  2) 
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  3) Ricoh RN5T567/RN5T618/RC5T619 is a power management IC family which
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  4) integrates 3 to 5 step-down DCDC converters, 7 to 10 low-dropout regulators,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  5) GPIOs, and a watchdog timer. It can be controlled through an I2C interface.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) The RN5T618/RC5T619 provides additionally a Li-ion battery charger,
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) fuel gauge, and an ADC.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) The RC5T619 additionnally includes USB charger detection and an RTC.
