Re: [alsa-devel] Fwd: [PATCH 1/1] SPI : spi-pxa2xx : fix spi init of WM510205 codec via ACPI (resend)

Hi at all,

the current logs shows me, that something else is missing here.
The spi irq is one of the issues I will try to solve today

Looking at the read_regmap() where it reads its device id,
I do not understand why it gots only an ID of 0xffff !

I have (silly or not), added a case for 0xffff in the next switch
statements but anyway this seems not okay.
I do not know what else (other than the wrong or missing spi irq,
which is currently only -1)

any ideas or what I can do next to find out was is the root issue here?
Question about the spi-irq to clarify it for me: does this spi irq
device belongs to the arizona child (the wm5102) or is this irq only
of the spi master ? I much as I understand, this irq is from the spi
master, the arizona spi child , the wm510205, has another irq ,
attachted at the irq_gpio - I am right so far??

in some previous mails it was mentioned, that I should or _must_ use
and irqchip handler?

still encouraged to get this device working as expected :)

cheers
