However, the timings written directly to the OTG registers will not be honoured unless VMIN/VMAX selector registers are programmed with the right bits and trigger source is selected correctly. Proper solution needs to go into DMCUB but will require additional state tracking to ensure that the selectors are set and reset correctly as per driver state. Until fix is merged into firmware, apply the workaround in driver to unconditionally write OTG vmin/vmax selectors.
