All new platforms should be supported by adding a Device Tree source
file, rather than using old-style C board files. Could you convert this
to the Device Tree and resubmit?

Thanks!

Very nice, glad someone found the time to do this. Maybe
I should buy one now ;-)

I'd like to move away from using 'earlyprintk' in dts files.
Can you remove this here and add a 'stdout-path' property that
can be used with 'earlycon'? Unfortunately 3.19 doesn't support
earlycon on ARM yet, but I hope to see that working in 3.20
at last.

Hi Christoph

Do you have any idea of the license on this file? Since there is
nothing stated, i assume it falls under the general Linux kernel
licence, GPL v2. Please could you add a normal GPLv2 header.

Documentation/leds/leds-class.txt says:

LED Device Naming
=================

Is currently of the form:

"devicename:colour:function"

Please could you change status to pogo_e02.

The rest looks good, and thanks for remembering the vendor.txt file.
