I would make GPIO a subdevive of chipcommon. The chipcommon core has an own IRQ which is also used for GPIO.Which ChipCommon do yo mean? 1) chipcommonA (compatible = "simple-bus") 2) chipcommon at 0 (child of axi at 18000000 AKA brcm,bus-axi)
We should combine this (both are describing the same core) I added chipcommonA to get some serial without adding bcma support first. When we have dts support added to bcma, I would like to remove chipcommonA from dtsi and add a chipcommon as a child of axi.
It seems that for some reason both of them use IRQ 85, while the IRQ for ChipCommon is 117 I believe.
That's the same. In the dtsi file it says: interrupts = <GIC_SPI 85 IRQ_TYPE_LEVEL_HIGH>; this will result in the IRQ number 117, when it is GIC_SPI you have to add 32 to the irq number to get the actual number which will be given to request_irq(). Hauke
