GND Island
Note 1
Note 1: Implement a GND island for PM8110 XOADC_GND,
C4102 and x4100 THRMST/GND that connects
to the GND plane of the (-) side of C4102.
Note 2: REF_GND must connect (via) directly to C4105;
C4105 GND must connect (via) directly to the main GND
without any other connections to intermediate GND fills.
