Hi Andre,
Thanks for detailed description. So Linux kernel can't access AXP803 at this moment. It means all LDO & BUCKs are controlled in boot code and are never changed at run time.
In other words, regulator driver should expose all them as statically - 'regulator-fixed' for regulator consumers.
Another problem is no way to handle AXP interrupts (like charger) in Linux because IRQ pin will be de-asserted by writing '1' to status bit.
Hi Pine64 team,
Do you have any plan to change PMIC interface from RSB to I2C (TWI) later?
Best regards,
Milo
