This patch adds code, which comply with TPS65903X errata pseudocode described in SLIA087 - "Guide to Using the GPADC in TPS65903x and TPS6591x Devices".
It is enabled by proper Kconfig option, when TI's palmas PMIC support is added.
The TI's e2e thread with test procedure description: https://e2e.ti.com/support/power_management/pmu/f/200/p/579649/2130910#21309...
I could not understand the reason for why this is being done in U-Boot. 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
