[PATCH v2 11/19] imx: kontron-sl-mx8mm: Remove 100mt DDR setpoint

Frieder Schrempf frieder at fris.de
Mon Aug 1 12:30:13 CEST 2022


From: Frieder Schrempf <frieder.schrempf at kontron.de>

The new stable configuration is missing the 100mt setpoint, remove
it before updating the config to make sure the changes are separated
cleanly.
