If I'm missing something, please let me know. The thing is that by default Exynos 4412 (trats2) can run with modified cpufreq to support SW governed overclocking (BOOST). To provide safe BOOST operation, TMU (thermal) _must_ be configured. Configuration is not possible when trats2 DTS lacks of those patches. So, yes there is a requirement to add those patches to v3.18 (if not possible please add it to v3.19). > > Thanks, > Kukjin > > > The TMU device tree node definition for Exynos4x12 family of SoCs. > > > > Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> > > Reviewed-by: Bartlomiej Zolnierkiewicz <b.zolnierkie@samsung.com> > > Reviewed-by: Tomasz Figa <tomasz.figa@gmail.com> > > --- > > arch/arm/boot/dts/exynos4x12.dtsi | 10 ++++++++++ > > 1 file changed, 10 insertions(+) > > > > diff --git a/arch/arm/boot/dts/exynos4x12.dtsi > > b/arch/arm/boot/dts/exynos4x12.dtsi index 861bb91..2e9f1f7 100644 > > --- a/arch/arm/boot/dts/exynos4x12.dtsi > > +++ b/arch/arm/boot/dts/exynos4x12.dtsi > > @@ -271,4 +271,14 @@ > > compatible = "samsung,exynos4x12-usb2-phy"; > > samsung,sysreg-phandle = <&sys_reg>; > > }; > > + > > + tmu at 100C0000 { > > + compatible = "samsung,exynos4412-tmu"; > > + interrupt-parent = <&combiner>; > > + interrupts = <2 4>; > > + reg = <0x100C0000 0x100>; > > + clocks = <&clock 383>; > > + clock-names = "tmu_apbif"; > > + status = "disabled"; > > + }; > > }; > > -- > > 2.0.0.rc2 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel at lists.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel -- Best regards, Lukasz Majewski Samsung R&D Institute Poland (SRPOL) | Linux Platform Group ^ permalink raw reply [flat|nested] 5+ messages in thread
