powerpc: Remove extra semicolon in fsl_soc.c

2009-03-23T22:00:05+00:00

TSEC/MDIO will not work with older device trees because of a semicolon
at the end of a macro resulting in an empty for loop body.

This fix only applies to 2.6.28; this code is gone in 2.6.29, according
to Grant Likely!

powerpc/mpic: Don't reset affinity for secondary MPIC on boot

2008-12-13T23:29:17+00:00

commit cc353c30bbdb84f4317a6c149ebb11cde2232e40 upstream.

Kexec/kdump currently fails on the IBM QS2x blades when the kexec happens
on a CPU other than the initial boot CPU.  It turns out that this is the
result of mpic_init trying to set affinity of each interrupt vector to the
current boot CPU.

As far as I can tell,  the same problem is likely to exist on any
secondary MPIC, because they have to deliver interrupts to the first
output all the time. There are two potential solutions for this: either
not set up affinity at all for secondary MPICs, or assume that a single
CPU output is connected to the upstream interrupt controller and hardcode
affinity to that per architecture.

This patch implements the second approach, defaulting to the first output.
Currently, all known secondary MPICs are routed to their upstream port
using the first destination, so we hardcode that.

powerpc/mpic: Fix regression caused by change of default IRQ affinity

2008-11-20T22:54:47+00:00

commit 3c10c9c45e290022ca7d2aa1ad33a0b6ed767520 upstream.

The Freescale implementation of MPIC only allows a single CPU destination
for non-IPI interrupts.  We add a flag to the mpic_init to distinquish
these variants of MPIC.  We pull in the irq_choose_cpu from sparc64 to
select a single CPU as the destination of the interrupt.

This is to deal with the fact that the default smp affinity was
changed by commit 18404756765c713a0be4eb1082920c04822ce588 ("genirq:
Expose default irq affinity mask (take 3)") to be all CPUs.

cpm2: Fix race condition in CPM2 GPIO library.

powerpc: fix memory leaks in QE library

2008-08-21T04:58:12+00:00

Fix two memory leaks in the Freescale QE library: add a missing kfree() in
ucc_fast_init() and ucc_slow_init() if the ioremap() fails, and update
ucc_fast_free() and ucc_slow_free() to call iounmap() if necessary.

Based on a patch from Tony Breeds .

cpm2: Rework baud rate generators configuration to support external clocks.

2008-07-28T13:47:45+00:00

The CPM2 BRG setup functions cpm_setbrg and cpm2_fastbrg don't support
external clocks. This patch adds a new exported __cpm2_setbrg function
that takes the clock rate and clock source as extra parameters, and moves
cpm_setbrg and cpm2_fastbrg to include/asm-powerpc/cpm2.h where they
become inline wrappers around __cpm2_setbrg.

powerpc: rtc_cmos_setup: assign interrupts only if there is i8259 PIC

2008-07-28T13:47:38+00:00

i8259 PIC is disabled on MPC8610HPCD boards, thus currently rtc-cmos
driver fails to probe.

To fix the issue, we lookup the device tree for "chrp,iic" and
"pnpPNP,000" compatible devices, and if not found we do not assign RTC
IRQ and assuming that i8259 was disabled.

Though this patch fixes RTC on some boards (and surely should not break
any other), the whole approach is still broken. We can't easily fix this
though, because old device trees do not specify i8259 interrupts for the
cmos rtc node.
