[U-Boot] [PATCH] ARM: mxs: fix VDDD brownout setting

2015-11-15 Thread Michael Heimpold
At the moment, the desired brownout is at 1.0V. However, this setting cannot be realized by hardware since we have only 3 bits to represent the voltage difference from the target value. Target value is 1500 mV, brownout target is 1000 mV, voltage steps are 25 mV. Register content calculation: (
