Some PSUs on AS4610-30 and AS4610-54 have a defect where reading out v_out/i_out/p_out values while only one PSU is connected causes system lockups and subsequent resets from the watchdog. Since these values are non-essential, just disable the readout of the values. As we do not know exactly which PSU models are affected, disable it for everyone for now. This is a partial revert of 24efd4f. Fixes: 24efd4f ("[as4610] Support Delta PSU DPS-920AB") Signed-off-by: Jonas Gorski <[email protected]>

Thank you for your patch. Could you list (a non-complete) list of PSUs you saw this with? That’d be grand. |

Personally we experienced it with YM-1921 on AS4610-54P, and we got a report for YM-1601A on AS4610-30P affected by the same issue. since the reset triggers shortly after boot, it is not easy to work around on an affected device. |
