Subject: [RFC PATCH 00/13] Support ROHM BD72720 PMIC

The ROHM BD72720 is a new power management IC for portable, battery
powered devices. It integrates 10 BUCKs and 11 LDOs, RTC, charger, LEDs,
GPIOs and a clock gate. To me the BD72720 seems like a successor to the
BD71828 and BD71815 PMICs.

The reason for RFC status is the addition of VDR battery parameters in
the device tree (patch 3) and the fact that BD72720 uses two different
I2C slave addresses.

This series depends on the series: "[PATCH v5 0/3] power: supply: add
charger for BD71828":
https://lore.kernel.org/all/20250918-bd71828-charger-v5-0-851164839c28@kemnade.info/
sent by Andreas, which is not yet merged. I will rebase this on
v6.18-rc1 when it is out, to see what dependencies are still missing.
