AVDD18_MEMPLL pin and AVSS18_MEMPLL pin should
be connected with PCB CAP first, and then connected
with PMU and PCB ground. CAP should be near MT6582 as possible as we can.
(2)R108 & R109 must be close to 1st cap group.
If you want to remove them,
please make sure the VPROC_FB/GND_VPROC_FB must connect from 1st cap. group of VPROC

Please refer to MT6323 design notice for
Buck GND layout rule
(1)MT6323 Buck GND(GND_VPROC/GND_VPA/GND_VSYS) is connected together first, and then single
trace connect to GND layer
(2)Use single trace >40mil or GND plan to connect buck input bypass cap and MT6323 GND
pins of buck in the same layer,
and then isolate this GND plan
