| |
Set the requested SM2 voltage to the correct value of 1.8V. The value before used to work on TPS658623 since the driver applied a wrong voltage table too. However, the TPS658643 used on newer devices uses yet another voltage table and those broke that compatibility. The regulator driver now has the correct voltage table for both regulator versions and those the correct voltage can be used in this device tree.
