2008-01-26[I2C] i2c-mv64xxx: Don't set i2c_adapter.retriesJean Delvare1-6/+0
I2C adapter drivers are supposed to handle retries on nack by themselves if they do, so there's no point in setting .retries if they don't. As this retry mechanism is going away (at least in its current form), clean this up now so that we don't get build failures later. Signed-off-by: Jean Delvare <[email protected]> Acked-by: Mark A.

2008-01-25[POWERPC] Enable RTC for Ebony and Walnut (v2)David Gibson2-0/+60
This patch extends the Ebony and Walnut platform code to instantiate the existing ds1742 RTC class driver for the DS1743 RTC/NVRAM chip found on both those boards. The patch uses a helper function to scan the device tree and instantiate the appropriate platform_device based on it, so it should be easy to extend for other boards which have mmio mapped RTC chips. Along with this, the device tree binding for the ds1743 chips is tweaked, based on the existing DS1385 OF binding found at: http://playground.sun.com/1275/proposals/Closed/Remanded/Accepted/346-it.txt Although that document covers the NVRAM portion of the chip, whereas here we're interested in the RTC portion, so it's not entirely clear if that's a good model. This implements only RTC class driver support - that is /dev/rtc0, not /dev/rtc, and the low-level get/set time callbacks remain unimplemented. That means in order to get at the clock you will either need a modified version of hwclock which will look at /dev/rtc0, or you'll need to configure udev to symlink rtc0 to rtc.

2007-12-28[POWERPC] pasemi: Distribute interrupts evenly across cpusOlof Johansson1-0/+5
By default the OpenPIC on PWRficient will bias to one core (since that will improve changes of the other core being able to stay idle/powered down). However, this conflicts with most irq load balancing schemes, since setting an interrupt to be delivered to either core doesn't really result in the load being shared. It also doesn't work well with the soft irq disable feature of PPC, since EE will stay on until the first interrupt is taken while soft disabled. Set the gconf0 config bit that enables even distribution of interrupts among the two cores. Signed-off-by: Olof Johansson <[email protected]>
2007-12-28[POWERPC] pasemi: Implement NMI supportOlof Johansson2-6/+23
Some PWRficient-based boards have a NMI button that's wired up to a GPIO as interrupt source. By configuring the openpic accordingly, these get delivered as a machine check with high priority, instead of as an external interrupt. The device tree contains a property "nmi-source" in the openpic node for these systems, and it's the (hwirq) source for the input. Also, for these interrupts, the IACK is read from another register than the regular (MCACK instead), but they are EOI'd as usual. So implement said function for the mpic driver. Finally, move a couple of external function defines to include/ instead of local under sysdev. Being able to mask/unmask and eoi directly saves us from setting up a dummy irq handler that will never be called. Signed-off-by: Olof Johansson <[email protected]>

2007-12-23[POWERPC] 4xx: rework UIC cascade irq handlingValentine Barshak1-17/+19
This is a UIC cascade handler rework to use set_irq_chained_handler() for cascade, just like othe ppc platforms do. With current implementation we have additional redirection for irq handler and we call generic_handle_irq twice (once for the primary uic and the other time for handling cascade interrupt). This causes Ingo's realtime support patch to stop working on 4xx. Not sure of any other possible problems though, but with set_irq_chained_handler() we can abolish "struct irqaction cascade" from the chip descriptor and call generic_handle_irq() once, directly for cascade irq.

2007-12-23[POWERPC] 4xx: make UIC use generic level irq handlerValentine Barshak1-62/+19
This patch makes PowerPC 4xx UIC use generic level irq handler instead of a custom handle_uic_irq() function. We ack only edge irqs in mask_ack callback, since acking a level irq on UIC has no effect if the interrupt is still asserted by the device, even if the interrupt is already masked. So, to really de-assert the interrupt we need to de-assert the external source first *and* ack it on UIC then. The handle_level_irq() function masks and ack's the interrupt with mask_ack callback prior to calling the actual ISR and unmasks it at the end. So, to use it with UIC interrupts we need to ack level irqs in the unmask callback instead, after the ISR has de-asserted the external interrupt source. Even if we ack the interrupt that we didn't handle (unmask/ack it at the end of the handler, while next irq is already pending) it will not de-assert the irq, untill we de-assert its exteral source.

2007-12-23[POWERPC] 4xx: Add 440SPe revA runtime detection to PCIeStefan Roese1-8/+17
This patch adds runtime detection of the 440SPe revision A chips. These chips are equipped with a slighly different PCIe core and need special/ different initialization. The compatible node is changed to "plb-pciex-440spe" ("A" and "B" dropped). This is needed for boards that can be equipped with both PPC revisions like the AMCC Yucca.

2007-12-23[POWERPC] 4xx: PCI-E Link setup improvementsBenjamin Herrenschmidt2-89/+133
This improves the way the 4xx PCI-E code handles checking for a link and adds explicit testing of CRS result codes on config space accesses. This should make it more reliable. Also, bridges with no link are now still created, though config space accesses beyond the root complex are filtered. This is one step toward eventually supporting hotplug.

2007-12-23[POWERPC] 4xx: PLB to PCI Express supportBenjamin Herrenschmidt3-18/+1226
This adds to the previous 2 patches the support for the 4xx PCI Express cells as found in the 440SPe revA, revB and 405EX. Unfortunately, due to significant differences between these, and other interesting "features" of those pieces of HW, the code isn't as simple as it is for PCI and PCI-X and some of the functions differ significantly between the 3 implementations. Thus, not only this code can only support those 3 implementations for now and will refuse to operate on any other, but there are added ifdef's to avoid the bloat of building a fairly large amount of code on platforms that don't need it. Also, this code currently only supports fully initializing root complex nodes, not endpoint. Some more code will have to be lifted from the arch/ppc implementation to add the endpoint support, though it's mostly differences in memory mapping, and the question on how to represent endpoint mode PCI in the device-tree is thus open. Many thanks to Stefan Roese for testing & fixing up the 405EX bits !

This adds to the 32 bits PCI code some flags, replacing the old pci_assign_all_busses global, that allow us to control various aspects of the PCI probing, such as whether to re-assign all resources or not, or to not try to assign anything at all.

2007-12-20[POWERPC] pasemi: Implement MSI supportOlof Johansson4-1/+200
Implement MSI support for PA Semi PWRficient platforms. MSI is done through a special range of sources on the openpic controller, and they're unfortunately breaking the usual concepts of how sources are programmed: * The source is calculated as 512 + the value written into the MSI register * The vector for this source is added to the source and reported through IACK This means that for simplicity, it makes much more sense to just set the vector to 0 for the source, since that's really the vector we expect to see from IACK. Also, the affinity/priority registers will affect 16 sources at a time. To avoid most (simple) users from being limited by this, allocate 16 sources per device but use only one. This means that there's a total of 32 sources. If we get usage scenarions that need more sources, the allocator should probably be revised to take an alignment argument and size, not just do natural alignment. Finally, since I'm already touching the MPIC names on pasemi, rename the base one from the somewhat odd " PAS-OPIC " to "PASEMI-OPIC".
