wrong it would be nice to let the kernel print a big fat
warning when this is registered.
Cheers,

Is it possible to somehow make use of the mpc52xx_pic mask funtions?
For this case that would be quite valid as the gpt as interrupt
controller only provides one interrupt, so masking one is the same as
masking 'all' on the parent.

I'm trying to make use of the GPT as interrupt controller.
My driver is getting most, but not all of the interrupts, besides that
I'm getting a whole bunch of spurious IRQs, so I'm trying to figure
out what's wrong.

Or does one of them not really swap bytes?

I just saw that I missed an earlier very useful a suggestion from Grant Likely:
http://ozlabs.org/pipermail/linuxppc-dev/2009-February/068357.html
By defining the irq in the dts directly I don't need the gpio irq
support anymore.

As far as I understand the DTS bindings now support an SPI master controller to
- use the chip-selects controlled directly by the SPI master controller hardware
or
- to use GPIO's trough gpiolib as chip selects
but not a combination of both, am I right?
Now every SPI driver needs to be adapted to
ase only byte swap u16 reads, but a u8 read is unchanged?
- What about how the DM9000 driver deals with this u8 read and u16
read, is this correct?
Thanks,
Henk

Hello,
I discovered the hard way that because linux bridging uses
net_device_ops, bridging only works with network drivers that publish
their device operations trough net_device_ops.
In my case running:
brctl addif br0 eth0 (where eth0 fec_mpc52xx.c did not yet support
net_device_ops) gave me a:
l as example for adding the of support to my 'own' spi slave
driver.
(Thanks Anton,)
Henk.

Then my smc4000io_of_probe function never gets called.
Thanks in advance,

In my dts
I have my chipselect defined as follows:
gpt4: [EMAIL PROTECTED] {// General Purpose Timer GPT4 in GPIO mode
for
SMC4000IO chip select.
compatible = "fsl,mpc5200b-gpt-gpio","fsl,mpc5200-gpt-gpio";
