This patch adds support for TPS6594 PMIC family on wakeup I2C0 bus.
These devices provide regulators (bucks and LDOs), but also GPIOs, a
RTC, a watchdog, an ESM (Error Signal Monitor) which monitors the SoC
error output signal, and a PFSM (Pre-configurable Finite State Machine)
which manages the operational modes of the PMIC.

only for the leaf nodes. See
https://libera.irclog.whitequark.org/armlinux/2023-10-19
AFAIK, please correct me, u-boot still needs in all nodes ?
That's what I believe as well, is it better to have only the leaf nodes in
kernel and have U-Boot DTSI handle the parent bootph properties? If so I'll send
out v10 making change accordingly.
