please consider applying the patches chained to this message. It's a rather simple driver for a power button on Dell Ariel board along with the Device Tree binding document. Compared to previous version, endianness issues are fixed and I connected a Reviewed-by for the binding doc that I failed to before. Change logs are present in individual patches. Note that this set is versioned "v2", but I've sent the previous version (both unversioned) out twice before, because I've forgotten about the previous submission before. Sorry if it caused a confusion. Thank you Lubo
