the possiblility that event CONFIG_OF is defined, but PWM is

Yeah I was thinking maybe we should not keep the legacy working if
CONFIG_OF is defined, but that should be OK:

This patch adds the generic IRQ support for the PCA9539 on-chip GPIOs.
This one bothers me a bit on some technical grounds. One problem is
that these chips are not designed for reliable IRQ management, so no

Jean,
I'd like to postpone the corresponding change to the point that
polling i2c patch is merged.

Also I'd like to fire another patch to obsolete drivers/i2c/chips/pca9539.c
as everyone agreed.

Also depends on GENERIC_HARDIRQS, right? (You should let

Based on a patch from Eric Miao.

The question I'm most interested in is whether it's worth paying the
extra data memory. I'm currently leaning towards yes, mostly since
it'll let me be lazy about some

OK, here's the all-in-one patch based on David's most recent gpiolib fix,
Changes include:
1. use per gpio structure "gpio_desc", thus eliminating the restriction of
ARCH_GPIOS_PER_CHIP, thus making it possible leaving no holes in GPIOs
numbering
Note: the number of GPIOs on different

Roughly went through the patch, looks good, here comes the remind, though :-)
1. is it possible to use some name other than "soc_core", maybe
"tmio_core" so that
other multifunction chips sharing a core base will live easier.
2. those C++ style comments "//" are not so pleasant...
