hi,all:
i saw peter's mpc8xxx_gpio.c in kernel 2.6.31. it seems that file can only
be used on 831x and others, but not mpc8323. my platform is mpc8323, how
can i use the GPIO?
i also found "QE GPIO Support" and "Support for simple, memory-mapped GPIO
controllers" selection, how can i use it an

Hi Ben,
Please find the version XV of the patch that ports the
hw-breakpoint interfaces (in kernel/hw_breakpoint.c) to PPC64. The new
patch includes the changes as listed below.
In particular, comments are sought about the changes in Kconfig, Makefile
and cputable.h and whether they clearl
Data address breakpoint exceptions are currently handled along with page-faults
which require interrupts to remain in enabled state. Since exception handling
for data breakpoints aren't pre-empt safe, we handle them separately.

Implement perf-events based hw-breakpoint interfaces for PPC64 processors.
These interfaces help arbitrate requests from various users and schedules
them as appropriate.

There were very few tests done with later kernel versions,
Define a binding for embedding a QE firmware blob into the device tree. Also
define a new property for the QE node that links to a firmware node.

thanks for replying.
it's my first time to use POWERPC,and i found it very different from ARM.
after i select "QE GPIO Suppor" in KConfig, i don't know how to use in
next step.
Because no device node was found in /dev, and the format of dts is strange
for me.
could you show me a little example?
Hi,
Is there an SPI Driver in Linux for CPM2 8260-based processors?
I'm quite surprised that there doesn't seem to be one. Can someone
please explain why this is?
Cheers,
Daniel
