Ping?
Are there any comments on any of the patches in the series?
Is there any specific tree AT91 patches should be based on now?
The at91 tree on github seems a bit out dated and during the last
merge window at91 stuff went via the pinctrl tree.
I have DT patches for my custom RM9200 board but they are a bit
useless without a more complete at91rm9200.dtsi.
