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>

This patch tightens up the behaviour of of_modalias_node() to be more predicatable and to eliminate the explicit of_modalias_tablep[] that is currently used to override the first entry in the compatible list of a device. The override table was needed originally because spi and i2c drivers had no way to do of-style matching. Now that all devices can have an of_node pointer, and all drivers can have an of_match_table, the explicit override table is no longer needed because each driver can specify its own OF-style match data. The mpc8349emitx-mcu driver is modified to explicitly specify the correct device to bind against. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca>

Implement generic OF gpio hooks and thus make device-enabled GPIO chips (i.e. the ones that have gpio_chip->dev specified) automatically attach to the OpenFirmware subsystem. Which means that now we can handle I2C and SPI GPIO chips almost* transparently. * "Almost" because some chips still require platform data, and for these chips OF-glue is still needed, though with this change the glue will be much smaller.

Currently the kernel uses the struct device_node.data pointer to resolve a struct gpio_chip pointer from a device tree node. However, the .data member doesn't provide any type checking and there aren't any rules enforced on what it should be used for. There's no guarantee that the data stored in it actually points to an gpio_chip pointer. Instead of relying on the .data pointer, this patch modifies the code to add a lookup function which scans through the registered gpio_chips and returns the gpio_chip that has a pointer to the specified device_node.

由 Anton Vorontsov 提交于
The OF gpio infrastructure is great for describing GPIO connections within the device tree. However, using a GPIO binding still requires changes to the gpio controller just to add an of_gpio structure. In most cases, the gpio controller doesn't actually need any special support and the simple OF gpio mapping function is more than sufficient. Additional, the current scheme of using of_gpio_chip requires a convoluted scheme to maintain 1:1 mappings between of_gpio_chip and gpio_chip instances. If the struct of_gpio_chip data members were moved into struct gpio_chip, then it would simplify the processing of OF gpio bindings, and it would make it trivial to use device tree OF connections on existing gpiolib controller drivers. This patch eliminates the of_gpio_chip structure and moves the relevant fields into struct gpio_chip (conditional on CONFIG_OF_GPIO). This move simplifies the existing code and prepares for adding automatic device tree support to existing drivers.

Merge common irq mapping code between PowerPC and Microblaze. This patch merges of_irq_find_parent(), of_irq_map_raw() and of_irq_map_one(). The functions are dependent on one another, so all three are merged in a single patch. Other than cosmetic difference (ie. DBG() vs. pr_debug()), the implementations are identical. of_irq_to_resource() is also merged, but in this case the implementations are different. This patch drops the microblaze version and uses the powerpc implementation unchanged. The microblaze version essentially open-coded irq_of_parse_and_map() which it does not need to do. Therefore the powerpc version is safe to adopt.

Now that the device tree node pointer has been moved out of struct of_device and into the common struct device, there isn't anything unique about of_device anymore. In fact, there isn't much need for a separate of_bus when all busses have access to OF style probing. arch/powerpc and arch/microblaze are moving away from using the of_bus and using the regular platform bus instead for mmio devices. This patch makes of_device the same as platform_device as a stepping stone in migrating of_platform_drivers over to the platform bus.

This patch moves SPARC architecture specific data members out of struct of_device and into the pdev_archdata structure. The reason for this change is to unify the struct of_device definition amongst all the architectures. It also remvoes the .sysdata, .slot, .portid and .clock_freq properties because they aren't actually used by anything. A subsequent patch will replace struct of_device entirely with struct platform_device and the of_platform support code will share common routines with the platform bus (but the bus instances themselves can remain separate). This patch also adds 'struct resources *resource' and num_resources to match the fields defined in struct platform_device. After this change, 'struct platform_device' can be used as a drop-in replacement for 'struct of_platform'. This change is in preparation for merging the of_platform_bus_type with the platform_bus_type. Signed-off-by: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S.
