Subject: [RFC PATCH 0/2] MFD and GPIO for STA2X11
These two patches introduce multi-function device and GPIO support for
the STA2X11 I/O Hub. It's an RFC for both as explained below.
- I think the MFD driver is ok. This MFD_STA2X11 config symbol is
autoselected by CONFIG_STA2X11, which is pending in the
"x86: initial support for sta2x11" patch, for which I need to send V2
later today, with some minor fixes. Similarly, <asm/sta2x11.h> is
not upstream yet, so I'll need to resend later, I suppose.
- The GPIO patch has a quirk: I chose to register a single irq chip
for 128 interrupts but the generic irq_chip only support 32 interrupts.
I'm sure the hack I did (request the irq descs myself) is not good, but
what is the best approach here? Using 4 generic irq chips or defining
my own, non-generic one?
Thanks a lot
