Quick question: for the auxiliar spi1 and spi2 of the BCM2835 chipset
should I create a separate driver - say spi-bcm2835aux.c - or incorporate
it into the exising spi-bcm2835.c driver.
Note that the register set for the auxiliar spi devices is totally
different
so any code-overlap with the existing spi-bcm2835.c would be minimal.
There is also an aux mini uart that shares interrupt with spi1/2.
The AUXIRQ register determines the interrupt source. How should this
sharing be done? This uart is really only useful on the Compute Module
since it's pins overlap the pl011 uart pins on the other boards.
This is how the mini uart is used/setup downstream:
