Hi,

Thanks you for your work.
Sorry, I dont hava a time at this week about this.
Its not a problem. We have plenty of time before the next merge
window. I was just interested in seeing it work on my QNAP device, so
did some of the cleanup work.

Some Orion SoC has thermal sensor.
This patch adds support for 88F6282 and 88F6283.

+
+This initial version is for Kirkwood 88F8262 & 88F6283 SoCs, however
+it is expected the driver will sometime in the future be expanded to
+also support Dove, using a different compatibility string.
+
+Required properties:
+- compatible : "marvell,kirkwood-thermal"
+- reg : Address range of the thermal registers
+
+Example:
+
+       thermal at 10078 {
+               compatible = "marvell,kirkwood";
compatible = "marvell,kirkwood-thermal"; ?
Yep, my error.

          If you say yes here you get support for TMU (Thermal Managment
          Unit) on SAMSUNG EXYNOS series of SoC.

Missed that one, thanks.

Thanks for the Tested-by. I will add it to the next version.  I
started work on Dove support, so i will probably repost when i have
that ready for testing.
