Hi Sébastien, Last time I checked there was a DC controller missing for the EVK, so I think it was not possible to go to the highest operating points yet. Have you tested this on the EVK? -- Stefan > > Signed-off-by: Sébastien Szymanski <sebastien.szymanski@armadeus.com> > --- > arch/arm/boot/dts/imx6ull.dtsi | 19 +++++++++++++++++++ > 1 file changed, 19 insertions(+) > > diff --git a/arch/arm/boot/dts/imx6ull.dtsi b/arch/arm/boot/dts/imx6ull.dtsi > index 571ddd71cdba..7e6273be0291 100644 > --- a/arch/arm/boot/dts/imx6ull.dtsi > +++ b/arch/arm/boot/dts/imx6ull.dtsi > @@ -46,6 +46,25 @@ > /* Delete UART8 in AIPS-1 (i.MX6UL specific) */ > /delete-node/ &uart8; > > +&cpu0 { > + operating-points = < > + /* kHz uV */ > + 900000 1275000 > + 792000 1225000 > + 528000 1175000 > + 396000 1025000 > + 198000 950000 > + >; > + fsl,soc-operating-points = < > + /* KHz uV */ > + 900000 1400000 > + 792000 1350000 > + 528000 1175000 > + 396000 1175000 > + 198000 1175000 > + >; > +}; > + > / { > soc { > aips3: aips-bus@2200000 {

No, I have tested on an OPOS6ULDev board. I've just noticed that the soc-operating-points values are wrong in this patch, I've sent a v2.

i.MX6ULL has different operating ranges than i.MX6UL so add the operating points for the i.MX6ULL. A 25mV offset is added to the minimum allowed values like for the i.MX6UL.
