[PATCH] ppc32: Apple device-tree bug fix

2005-06-01T14:54:13+00:00

This is the ppc32 patch equivalent to the just posted ppc64 one working
around a bug in Apple device-trees regarding the "cpus" nodes.

[PATCH] ppc32: Support for 82xx PQII on-chip PCI bridge

2005-05-28T23:46:15+00:00

This patch adds on-chip PCI bridge support for the PQ2 family.  The
incomplete existent code is updated with interrupt handling stuff and
board-specific bits for 8272ADS and PQ2FADS; the related files were renamed
(from m8260_pci to m82xx_pci) to be of more generic fashion.  This is
tested with 8266ADS and 8272ADS, should work on PQ2FADS as well.

[PATCH] ppc32: Add VIA IDE support to MPC8555 CDS platform

2005-05-28T23:46:15+00:00

Add support for the VIA IDE controller that exists on the MPC8555 CDS
system.  Updated the config for the system to enable support by default.

[PATCH] ppc32: Fix cpufreq vs. sleep issue

2005-05-28T18:14:01+00:00

Recent kernels occasionally trigger a PMU timeout on some mac laptops,
typically on wakeup from sleep.  This seem to be caused by either a too big
latency caused by the cpufreq switch on wakeup from sleep or by an
interrupt beeing lost due to the reset of the interrupt controller done
during wakeup.

This patch makes that code more robust by stopping PMU auto poll activity
around cpufreq changes on machines that use the PMU for such changes (long
latency switching involving a CPU hard reset and flush of all caches) and
by removing the reset of the open pic interrupt controller on wakeup (that
can cause the loss of an interrupt and Darwin doesn't do it, so it must not
be necessary).

[PATCH] ppc32: Fix an off-by-one error in ipic_init

2005-05-23T17:58:31+00:00

There is an off-by-one error in the IPIC code that configures the
external interrupts (Edge or Level Sensitive).

[PATCH] ppc32: Fix platform device initialization of 8250 serial ports

2005-05-20T22:48:19+00:00

Initialization of 8250 serial ports that are platform devices require that
at empty entry exists in the array of plat_serial8250_port.  With out an
empty entry we can get some pretty random behavior.

[PATCH] ppc32: workaround for spurious IRQs on PQ2

2005-05-01T15:58:42+00:00

There is a problem with large amounts of spurious IRQs on PowerPC 82xx
systems.

The problem is corrected by adding sync at the end of cpm2_mask_and_ack.
This may be needed on 8xx as well but has not yet been confirmed.

[PATCH] ppc iomem annotations: ->io_base_virt

2005-04-25T14:55:57+00:00

* ->io_base_virt in struct pci_controller is iomem pointer.  Marked as such.
  Most of the places that used it are already annotated to expect iomem.
* places that did gratitious (and wrong) casts a-la
	isa_io_base = (unsigned long)ioremap(...);
	hose->io_base_virt = (void *)isa_io_base;
  turned into
	hose->io_base_virt = ioremap(...);
	isa_io_base = (unsigned long)hose->io_base_virt;
* pci_bus_io_base() annotated as returning iomem pointer.
