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

[Christian Hartmann <cornogle-gM/Ye1E23mwN+BqQ9rBEUg@public.gmane.org>]

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
chris
