[PATCH 0/3] QorIQ TMU bindings and device tree update

[Jia Hongtao]

As Rui Zhang suggested I combine TMU binding patch and two device tree patchset
together. He will take all of them after the device tree patchset got ACK.

@Scott please help to review the device tree patchset.
Thanks.

[PATCH 1/3] dt-bindings: Update QorIQ TMU thermal bindings

[Jia Hongtao]

For different types of SoC the sensor id and endianness may vary.
"#thermal-sensor-cells" is used to provide sensor id information.
"little-endian" property is to tell the endianness of TMU.

I assume the driver will continue to work with existing device trees where
this information is absent?  If so, ACK for the whole series.

Yes. The driver works for all existing device trees.

Thanks for the ACK.

Seems like Troy's email client has issues which causes his reply is unreadable in patchwork.
Please ignore it in patchwork.

[PATCH 2/3] powerpc/mpc85xx: Update TMU device tree node for T1040/T1042

[Jia Hongtao]

From: Hongtao Jia <hongtao.jia@nxp.com>

Update #thermal-sensor-cells from 0 to 1 according to the new binding. The
sensor specifier added is the monitoring site ID, and represents the "n" in
TRITSRn and TRATSRn.

[Y.T. Tang]

++Scott NXP email address.

Hi Scott,

Could you please give these patch set a little higher priority as Troy's last day is Friday?
We want those get ACKed or address all the major issues before Friday.

Thanks,
Yuantian
