1. arch/powerpc/platforms/pasemi/gpio_mdio.c also needs to be converted over to mdiobus_{alloc,free}(). 2. drivers/net/phy/fixed.c used to embed a struct mii_bus into its struct fixed_mdio_bus and then use container_of() to go from the former to the latter. Since mii bus structures are no longer embedded, we need to do something like use the mii bus private pointer to go from mii_bus to fixed_mdio_bus instead.

In preparation of giving mii_bus objects a device tree presence of their own, rename struct mii_bus's ->dev argument to ->parent, since having a 'struct device *dev' that points to our parent device conflicts with introducing a 'struct device dev' representing our own device.

To support Cooperative Memory Overcommitment (CMO), we need to check for failure from some of the tce hcalls. These changes for the pseries platform affect the powerpc architecture; patches for the other affected platforms are included in this patch. pSeries platform IOMMU code changes: * platform TCE functions must handle H_NOT_ENOUGH_RESOURCES errors and return an error. Architecture IOMMU code changes: * Calls to ppc_md.tce_build need to check return values and return DMA_MAPPING_ERROR for transient errors. Architecture changes: * struct machdep_calls for tce_build*_pSeriesLP functions need to change to indicate failure. * all other platforms will need updates to iommu functions to match the new calling semantics; they will return 0 on success. The other platforms default configs have been built, but no further testing was performed.

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: NOlof Johansson <olof@lixom.net>

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: NOlof Johansson <olof@lixom.net>

Maple and pasemi both require PCI as does CONFIG_OF_PLATFORM_PCI. The default setting of CONFIG_ISA_DMA_API is set to match the protection around the relevant routines in asm/dma.h. I also had to remove the PMAC platform from the combined build. The precis is that to build a 64 bit kernel with no PCI, you can only include pSeries and iSeries.

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".

Currently we hardwire the number of SLBs to 64, but PAPR says we should use the ibm,slb-size property to obtain the number of SLB entries. This uses this property instead of assuming 64. If no property is found, we assume 64 entries as before. This soft patches the SLB handler, so it shouldn't change performance at all.

-
由 Olof Johansson 提交于
When the PWRficient cpus are entered into powersavings states, the astate is automatically dropped down to 0. While we still restore it when we come out of idle, it can still cause some weird effects with respect to performance (especially since it takes a while to ramp up to higher astates). So, to avoid this, don't enter power savings when the cpufreq driver (or user) has set higher astates than 0. The restore is still required, since there's a chance the astate has been raised from the other cpu while the idling one was asleep. Signed-off-by: NOlof Johansson <olof@lixom.net>

Some versions of PWRficient 1682M have an interrupt controller in which the first register in each pair for interrupt sources doesn't always read with the right polarity/sense values. To work around this, keep a software copy of the register instead. Since it's not modified from the mpic itself, it's a feasible solution.
