Both ICs provide + also a single-cell linear charger, a Coulomb counter, a real-time + clock (RTC), GPIOs and a 32.768 kHz clock gate. config MFD_STM32_LPTIMER tristate "Support for STM32 Low-Power Timer" diff --git a/drivers/mfd/rohm-bd71828.c b/drivers/mfd/rohm-bd71828.c index 210261d026f2..714d9fcbf07b 100644 --- a/drivers/mfd/rohm-bd71828.c +++ b/drivers/mfd/rohm-bd71828.c @@ -2,7 +2,7 @@ // // Copyright (C) 2019 ROHM Semiconductors // -// ROHM BD71828 PMIC driver +// ROHM BD71828/BD71815 PMIC driver #include #include @@ -11,7 +11,9 @@ #include #include #include +#include #include +#include #include #include #include @@ -29,12 +31,84 @@ static struct gpio_keys_platform_data bd71828_powerkey_data = { .name = "bd71828-pwrkey", };

The IC has two GPO pins but only one is properly documented in the data-sheet. The driver exposes by default only the documented GPO. The second GPO is connected to E5 pin and is marked as GND in the data-sheet. Control for this undocumented pin can be enabled using a special DT property. This driver is derived from work by Peter Yang although not so much of the original is left.
