The defconfig changes don't seem to have been done with a "savedefconfig" (one add a blank line at the end for example), but you can hold off on v2'ing things, barring other feedback, until the DTS situation is resolved.
TPS6594 is a Power Management IC which provides regulators and others features like GPIOs, RTC, watchdog, ESMs (Error Signal Monitor), and PFSM (Pre-configurable Finite State Machine). The SoC and the PMIC can communicate through the I2C or SPI interfaces. TPS6594 is the super-set device while TPS6593 and LP8764X are derivatives. This series fixes LDO voltage conversion for TPS6594 PMIC, it adds support for its derivatives. The features implemented are: - Regulators - WD disable WD disable is not a watchdog driver implementation. Watchdog is active by default causing a reboot even if not used. This implementation allow to disable the watchdog at boot time. Due to current situation with upstream u-boot dts, this patch suite can be applied only after u-boot dts upstream is resynched on latest Linux dts.
