This is a simple automated notification to let you know that 
I've just added the patch titled

    thermal: armada: Update Armada 380 thermal sensor coefficients

to my thermal-soc git tree which can be found at
    git://git.kernel.org/pub/scm/linux/kernel/git/evalenti/linux-soc-thermal.git
in the fixes branch.

The patch will show up in the next release of the linux-next tree
(usually sometime within the next 24 hours during the week.)

The patch will hopefully also be merged in Linus's tree for the
next -rc kernel release.

If you have any questions about this process, please let me know.

All the best,

Eduardo Valentin

Subject: thermal: armada: Update Armada 380 thermal sensor coefficients

Improve the Armada 380 thermal sensor accuracy by using updated formula.
The updated formula is:
Temperature[C degrees] = 0.4761 * tsen_vsen_out - 279.1
