j721e board includes 2 instances of TPS6594: - Primary PMIC - Secondary PMIC Add AVS class0 in u-boot SPL. AVS is supported only on CPU rail: vdd_cpu_avs. This rail is supplied by the primary PMIC: tps659413 This rail is supplied by a dual-phased buck: buck12. Other PMICs rails are not AVS capable. Each PMIC includes a Watchdog that is active by default at boot. This would issue a platform reset unless pmic GPIO8 is driven or this is handled by SW. Watchdog driver is not required for identified use of this product. This software disable inside u-boot avoids parasitic wd reset. GPIO8 can then be used for other purpose.
