Subject: dts: update gpu freq tbl for 32bit kernel [1/1]
X-Git-Tag: hardkernel-4.9.236-104~1380
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=c912a3d588b388c2385bc8dd8aa955eaad8660da;p=platform%2Fkernel%2Flinux-amlogic.git

dts: update gpu freq tbl for 32bit kernel [1/1]

PD#SWPL-4253

Problem:
Compared with P212, GPU on g12a can not work with high
frequency
when running some cases like particle;

Solution:
update gpu freq tbl for buildroot

Verify:
build pass
GPU on g12a can work with high
freq when running particle
