Hi All, 

where can i get patches of 


5837              Setting the ENABLE_DCDC bit in the HW_POWER_DCDC4P2 or HW_POWER_5VCTRL registers can result in false brownout Detection


The problem is when ever i insert USB wifi module, i am seeing a drop in VDD causes device to shut down , so i was suspecting the 5837 patch should , which i am not sure


i didnt find the patch


Following is the log
