[Bug 1248233] [NEW] [saucy][armhf] No early printk because there's no defined device tree binding for earlyprintk UART

 

Public bug reported:

There is no earlyprintk via the PL011 because there's no defined device
tree binding for earlyprintk UART to get the PL011 to work you'll need
to tweak the kernel a bit. kernel doesn't ever add the clock to its
list, and then it refuses to probe for the PL011. This is a temporary
fix, ideally the call should be done in some generic location rather
than in every machine's init function.) The alternative would be for the
kernel to be fixed to follow its own device tree binding documentation
and not require clocks/clock-names properties on the pl011 node.
