[PATCH v3 0/2] Enable lm90 in Tegra30 and Tegra114.

[Wei Ni]

Enable thermal sensor lm90 for Tegra30 Cardhu and Tegra114 Dalmore.

This series is v2, previous version patches:
[RFC 1/9]: http://thread.gmane.org/gmane.linux.power-management.general/31056
[v1]: http://thread.gmane.org/gmane.linux.ports.tegra/11713/
[v2]: http://www.mail-archive.com/linux-kernel@vger.kernel.org/msg465561.html

Changes from v2:
1. remove the label "nct1008".

Changes from v1:
1. add vendor strings "onnn" for nct1008 node.

Changes from RFC:
1. Enable it for Tegra114 Dalmore.

Actually, I see the following on Dalmore (although Cardhu works):

[   29.448539] lm90 0-004c: Register 0x4 read failed (-121)
[   29.453930] lm90 0-004c: Failed to read convrate register!
[   29.460034] lm90 0-004c: Register 0x3 read failed (-121)
[   29.465408] lm90 0-004c: Initialization failed!

So, there's something wrong here, and I've dropped the patch for
Dalmore. Does this patch actually work for you?

I test it with the Chrome u-boot, the lm90 works fine.
But today, if I tried to use the uboot from
git://git.denx.de/u-boot-tegra.git, I can repo your errors, it seems the
i2c can't work, the lm90 driver read register failed.
I traced it, but can't find the root cause yet.

Hi, Stephen
I found the root cause.
In the Chrome u-boot, it will turn on the regulator for the lm90, but in
the upstream u-boot, it didn't do it.
I think this regulator should be handled in the kernel driver, but it
seems the regulator palmas tps65913 didn't be supported on the dalmore yet.
So may be we have to wait the palmas ready on dalmore.

Do you have any suggestions?

Thanks.
Wei.

Hi, Stephen
I found the root cause.
In the Chrome u-boot, it will turn on the regulator for the lm90, but in
the upstream u-boot, it didn't do it.
I think this regulator should be handled in the kernel driver, but it
seems the regulator palmas tps65913 didn't be supported on the dalmore yet.
So may be we have to wait the palmas ready on dalmore.

Do you have any suggestions?

Thanks.
Wei.

A patch to enable tps65913 on dalmore has already been posted a couple 
of days
ago by Laxman Dewangan, so this shouldn't be too problematic.

Yes, I agree. (although Laxman's regulator patch caused the SD card to
stop working, so that needs to be fixed up, but hopefully it's a simple
issue).
