This patch adds device tree support for contiguous and reserved memory regions defined in device tree. Large memory blocks can be reliably reserved only during early boot. This must happen before the whole memory management subsystem is initialized, because we need to ensure that the given contiguous blocks are not yet allocated by kernel. Also it must happen before kernel mappings for the whole low memory are created, to ensure that there will be no mappings (for reserved blocks) or mapping with special properties can be created (for CMA blocks). This all happens before device tree structures are unflattened, so we need to get reserved memory layout directly from fdt. Later, those reserved memory regions are assigned to devices on each device structure initialization.

I2C of helpers used to live in of_i2c.c but experience (from SPI) shows that it is much cleaner to have this in the core. This also removes a circular dependency between the helpers and the core, and so we can finally register child nodes in the core instead of doing this manually in each driver. So, fix the drivers and documentation, too. Signed-off-by: NWolfram Sang <wsa@the-dreams.de>

Only two architectures use the OF node reference counting and reclaim bits. There is no need to compile it for the rest of the PowerPC platforms or for any of the other architectures. This patch makes iseries and pseries select CONFIG_OF_DYNAMIC, and makes it default to off for everything else. It is still safe to turn on CONFIG_OF_DYNAMIC on all architectures, it just isn't necessary. v2: Also select OF_DYNAMIC for PPC_CHROMA and MPC885ADS as reported by Michael Meuling Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S.

由 Benjamin Herrenschmidt 提交于
powerpc has two different ways of matching PCI devices to their corresponding OF node (if any) for historical reasons. The ppc64 one does a scan looking for matching bus/dev/fn, while the ppc32 one does a scan looking only for matching dev/fn on each level in order to be agnostic to busses being renumbered (which Linux does on some platforms). This removes both and instead moves the matching code to the PCI core itself. It's the most logical place to do it: when a pci_dev is created, we know the parent and thus can do a single level scan for the matching device_node (if any). The benefit is that all archs now get the matching for free. There's one hook the arch might want to provide to match a PHB bus to its device node. A default weak implementation is provided that looks for the parent device device node, but it's not entirely reliable on powerpc for various reasons so powerpc provides its own.

x86_of_pci_init() does two things: - it provides a generic irq enable and disable function. enable queries the device tree for the interrupt information, calls ->xlate on the irq host and updates the pci->irq information for the device. - it walks through PCI bus(es) in the device tree and adds its children (device) nodes to appropriate pci_dev nodes in kernel. So the dtb node information is available at probe time of the PCI device. Adding a PCI bus based on the information in the device tree is currently not supported. Right now direct access via ioports is used.

The device tree code is now in two pieces: some which can be used generically on any platform which selects CONFIG_OF_FLATTREE, and some early which is used at boot time on only a few architectures. This patch segregates the early code so that only those architectures which care about it need compile it. This also means that some of the requirements in the early code (such as a cmd_line variable) that most architectures (e.g. X86) don't provide can be ignored.

All of the options in drivers/of/Kconfig depend on CONFIG_OF. Putting all of them inside a menu block simplifies the dependency statements. It also creates a logical group for adding user selectable OF options. This patch also changes (PPC_OF || MICROBLAZE) statements to (!SPARC) so that those options are available to other architectures (and in fact the !SPARC conditions should probably be re-evalutated since the code is more generic now) This patch also moves the definition of CONFIG_DTC from arch/* to drivers/of/Kconfig Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

Add support for parsing the device tree for PHY devices on an MDIO bus. Currently many of the PowerPC ethernet drivers are open coding a solution for reading data out of the device tree to find the correct PHY device. This patch implements a set of common routines to: a) let MDIO bus drivers register phy_devices described in the tree, and b) let MAC drivers find the correct phy_device via the tree.

This patch adds functionality to the gpio-lib subsystem to make it possible to enable the gpio-lib code even if the architecture code didn't request to get it built in. The archtitecture code does still need to implement the gpiolib accessor functions in its asm/gpio.h file. This patch adds the implementations for x86 and PPC. With these changes it is possible to run generic GPIO expansion cards on every architecture that implements the trivial wrapper functions. Support for more architectures can easily be added.
