X-Git-Tag: hardkernel-4.9.236-104~2064
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=224663383fbb1e6caa2e11a32b3b6b87090b38df;p=platform%2Fkernel%2Flinux-amlogic.git

lcd: update tcon_pll lock setting for tl1 [1/1]

PD#SWPL-2983

Problem:
tcon_pll lock is affected by VDDEE voltage

Solution:
change tcon_pll lock setting to avoid VDDEE effection

Verify:
x301
