Subject: hdmitx: modify fractional part of hpll for gxtvbb [1/1]
X-Git-Tag: hardkernel-4.9.236-104~871

hdmitx: modify fractional part of hpll for gxtvbb [1/1]

PD#TV-8224

Problem:
hdmitx output clk is not right, actually output 145Mhz
when expect to output 148.5Mhz. for gxtvbb, bit[11]
of DIV_FRAC bit[11:0] is used for +/- symbol, but now
is used for fractional weight by mistake.

Solution:
change back to original setting for DIV_FRAC

Verify:
TCL-T966
