Sleep on the powerbook 3400 has been broken since the change that made powerbook_sleep_3400 call pmac_suspend_devices(), which disables interrupts. There are a couple of loops in powerbook_sleep_3400 that depend on interrupts being enabled, and in fact it has to have interrupts enabled at the point of going to sleep since it is an interrupt from the PMU that wakes it up. This fixes it by using pmu_wait_complete() instead of a spinloop, and by explicitly enabling interrupts before putting the CPU into sleep mode (which is OK since all interrupts except the PMU interrupt have been disabled at the interrupt controller by this stage). This changes the logic so that it keeps putting the CPU into sleep mode until the completion of the interrupt transaction from the PMU that signals the end of sleep. Also, we now call pmu_unlock() before sleep so that the via_pmu_interrupt() code can process the interrupt event from the PMU properly. Now that generic code saves and restores PCI state, it is no longer necessary to do that here. Thus pbook_pci_save/restore and related functions are no longer necessary, so this removes them. Lastly, this moves the ioremap of the memory controller to init code rather than doing it on every sleep/wakeup cycle. Signed-off-by:Paul Mackerras <paulus@samba.org>

This is fairly straightforward, and lets us get rid of x.completion as well. Signed-off-by: -

This converts the therm_pm72.c driver to use the kthread API. I thought about making it use kthread_stop() instead of the `state' variable and the `ctrl_complete' completion, but that isn't simple and will require changing the way that `state' is used. Signed-off-by: -

This converts adb.c to use the kthread API. It also changes adb_request so that if the ADBREQ_SYNC flag is specified, we now sleep waiting for the request to finish using an on-stack completion rather than spinning. To implement this, we now require that if the ADBREQ_SYNC flag is set, the `done' parameter must be NULL. All of the existing callers of adb_request that pass ADBREQ_SYNC appear to be in process context and have done == NULL. Doing this allows us to get rid of an awful hack in adb_request() where we used to test whether the request was coming from the adb probe task and use a completion if it was, and otherwise spin. This also gets rid of a static request block that was used if the req parameter to adb_request was NULL. None of the callers do that any more, so the static request block is no longer necessary.

Updates the ucc_geth device driver to check the new rx-clock-name and tx-clock-name properties first. If present, it uses the new function qe_clock_source() to obtain the clock source. Otherwise, it checks the deprecated rx-clock and tx-clock properties. Update the device trees for 832x, 836x, and 8568 to contain the new property names only. Signed-off-by:

Add function qe_clock_source() which takes a string containing the name of a QE clock source (as is typically found in device trees) and returns the matching enum qe_clock value. Update booting-without-of.txt to indicate that the UCC properties rx-clock and tx-clock are deprecated and replaced with rx-clock-name and tx-clock-name, which use strings instead of numbers to indicate QE clock sources.

Only external interrupts in edge detect mode support ack operation. Therefore, in most cases ack is not needed. The patch makes ipic ack only when it's needed. This could boost over all system performance. Signed-off-by:

This makes the early debug option force the console loglevel to the max. The early debug option is meant to catch messages very early in the kernel boot process, in many cases, before the kernel has a chance to parse the "debug" command line argument. Thus it makes sense when CONFIG_PPC_EARLY_DEBUG is set, to force the console log level to the max at boot time. Signed-off-by:

The 32 bits PCI code will display a rather scary error message PCI: Cannot allocate resource region N of device XXX at boot when the existing setup of a device as left by the firmware doesn't match the kernel needs and the device needs to be moved. This is often not an error at all, as the kernel will generally easily reallocate the device elsewhere. This changes the message to something less scary and lowers its level from error to warning.

The 32-bit powerpc resource fixup code uses unsigned longs to do the offsetting of resources which overflows on platforms such as 4xx where resources can be 64 bits. This fixes it by using resource_size_t instead. However, the IO stuff does rely on some 32 bits arithmetic, so we hack by cropping the result of the fixups for IO resources with a 32 bits mask. This isn't the prettiest but should work for now until we change the 32 bits PCI code to do IO mappings like 64 bits does, within a reserved are of the kernel address space. Signed-off-by:

This merges the 32-bit and 64-bit implementations of pci_process_bridge_OF_ranges(). The new function is cleaner than both the old ones, and supports 64 bits ranges on ppc32 which is necessary for the 4xx port. It also adds some better (hopefully) output to the kernel log which should help diagnose problems and makes better use of existing OF parsing helpers (avoiding a few bugs of both implementations along the way). There are still a few unfortunate ifdef's but there is no way around these for now at least not until some other bits of the PCI code are made common. Signed-off-by:

This defines isa_mem_base on both 32 and 64 bits (it used to be 32 bits only). This avoids a few ifdef's in later patches and potentially can allow support for VGA text mode on 64 bits powerpc. Signed-off-by:

This incorporates libfdt (from the source embedded in an earlier commit) into the wrapper.a library used by the bootwrapper. This includes adding a libfdt_env.h file, which the libfdt sources need in order to integrate into the bootwrapper environment, and a libfdt-wrapper.c which provides glue to connect the bootwrapper's abstract device tree callbacks to the libfdt functions. In addition, this changes the various wrapper and platform files to use libfdt functions instead of the older flatdevtree.c library. Signed-off-by:
