Can you explain a it more on this?
Just as a safety matter. Doing this for GPADC PMIC in u-boot avoids "surprises" latter on - when the high level user wants to use the GPADC results from the first measurement that he/she does (for example at safety critical application). The u-boot driver (as it touches it first) is responsible to give the TPS65903x PMIC to latter boot stage as free from any known problems (i.e erratas). > > Thanks and regards, > Lokesh Best regards, Lukasz Majewski -- DENX Software Engineering GmbH, Managing Director: Wolfgang Denk HRB 165235 Munich, Office: Kirchenstr.5, D-82194 Groebenzell, Germany Phone: (+49)-8142-66989-10 Fax: (+49)-8142-66989-80 Email: w...@denx.de _______________________________________________ U-Boot mailing list U-Boot@lists.denx.de https://lists.denx.de/listinfo/u-boot
