3.16 kernel features on QNAP TS-212p

Hi,

I have just installed Debian Stable on a new QNAP TS-212p (using the instructions at http://www.cyrius.com/debian/kirkwood/qnap/ts-219/install/), followed by kernel 3.16.0-0.bpo.4-kirkwood from wheezy-backports. I have three questions.

1. kirkwood-thermal (http://lxr.free-electrons.com/source/arch/arm/boot/dts/kirkwood-6282.dtsi?v=3.16 & http://lxr.free-electrons.com/source/drivers/thermal/kirkwood_thermal.c?v=3.16)

My TS-212p features MV88F6282 CPU (dmesg: Kirkwood: MV88F6282-Rev-A1, TCLK=200000000), for which a thermal driver 'kirkwood-thermal' is available. However, if I modprobe kirkwood-thermal, I get nothing in /sys/class/thermal. I assume this is a problem with the device tree? Should I file a bug for that?

2. cpuidle (http://lxr.free-electrons.com/source/drivers/cpuidle/cpuidle-kirkwood.c?v=3.16)

"# CONFIG_ARM_KIRKWOOD_CPUIDLE is not set" in the 3.16.0-0.bpo.4-kirkwood config. Is this intentional?

3. cpufreq-kirkwood (http://lxr.free-electrons.com/source/drivers/cpufreq/kirkwood-cpufreq.c?v=3.16)

"CONFIG_ARM_KIRKWOOD_CPUFREQ=y" is in the 3.16.0-0.bpo.4-kirkwood config but cpufreq-info reports that there is no driver active:

# cpufreq-info
cpufrequtils 008: cpufreq-info (C) Dominik Brodowski 2004-2009
Report errors and bugs to cpufreq@vger.kernel.org, please.
analyzing CPU 0:
no or unknown cpufreq driver is active on this CPU

dmesg | grep cpufreq yields nothing. Is it a bug?

Thanks for your help.
