Seemed a shame not to take this, so I've manually removed the DTS changes and applied this to the PWM tree. Aidan, probably best to resend the DTS snippet as a separate patch, unless Paul also wants to apply this manually. Thierry

I am not the arch/mips/ maintainer, so a separate patch would be needed anyway, yes. Cheers, -Paul
