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 [0] https://www.ti.com/lit/ds/symlink/am62p-q1.pdf Signed-off-by: Bryan Brattlof <redacted> --- arch/arm64/boot/dts/ti/k3-am62p5-sk.dts | 9 +++++++++ 1 file changed, 9 insertions(+)
