[PATCH 0/3] Update for AP807 thermal data

[PATCH 0/3] Update for AP807 thermal data

[Russell King (Oracle)]

Hi,

This series updates the thermal data for the AP807 die, which has
different coefficients to the AP806.

These patches have come from the SolidRun CN913x build repository
which can be found at:

[PATCH 2/3] thermal: armada: add support for AP807 thermal data

[Russell King]

From: Alex Leibovich <alexl@marvell.com>

Add support for the AP807 die thermal data. This is the same as AP806,
except for the coefficients.

ap807 values taken from TSENSE_ADC_16FFC spec, which says:
	T(in Celsius) = T(code)*TSENE_GAIN+TSENE_OFFSET
where in default:
	TSENE_OFFSET = 128.9
	TSENE_GAIN = 0.394

This is a TXT file, thus testing by some jenkins seems like a fake tag.

Applied, patch 1 and 2.

Dropped the sa_ip-sw-jenkins Tested-by tag

While working on some thermal optimizations, our hardware team
discovered that this patch is still missing upstream. Is something
missing or did it get lost?

Patch 1/3 had a change request. Was it ever reposted with the
requested change?

It would also be nice to convert the .txt to .yaml. The DT Maintainers
might insist on that when it is reposted?

I don't think so, it's just another patch series of many that I have
that's basically low priority, and other stuff probably overrode it
and I then forgot about it.

I forgot to mention that the other patches were applied, so it is only
the one missing without change request.

Ah. O.K. Repost it to the MVEBU Maintainers.
