Re: [PATCH] qe: add function qe_clock_source

UART, for instance, can use a CLK signal, but I wrote the driver to only

someone, for instance, could wire up his board to want to use external clocks 
for some UARTs, and so he'd need to modify the driver.

In the absence of a BRG, the driver should just not support changing the 
baud rate -- it shouldn't fail to function.
