[PATCH v6 4/6] arm64: dts: ti: k3-am62p5-sk: add 1.4ghz opp entry

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Bryan Brattlof <bb@xxxxxx>

The AM62Px reference board is capable of supplying 0v85 to the VDD_CORE
which allows the Cortex-A53s to operate at 1.4GHz according to chapter
6.6 of the SoC's data sheet[0] . Append the 1.4Ghz entry to the OPP
table to enable this frequency
