| * of: Merge of_platform_bus_type with platform_bus_typeGrant Likely2010-07-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | of_platform_bus was being used in the same manner as the platform_bus. The only difference being that of_platform_bus devices are generated from data in the device tree, and platform_bus devices are usually statically allocated in platform code. Having them separate causes the problem of device drivers having to be registered twice if it was possible for the same device to appear on either bus. This patch removes of_platform_bus_type and registers all of_platform bus devices and drivers on the platform bus instead. A previous patch made the of_device structure an alias for the platform_device structure, and a shim is used to adapt of_platform_drivers to the platform bus. After all of of_platform_bus drivers are converted to be normal platform drivers, the shim code can be removed. Signed-off-by: Grant Likely <grant.likely@secretlab.ca> Acked-by: David S.

| * | of/gpio: stop using device_node data pointer to find gpio_chipGrant Likely2010-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| * | of/gpio: Kill of_gpio_chip and add members directly to gpio_chipAnton Vorontsov2010-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Convert to the new cpumask API. irq_choose_cpu can be simplified by using cpumask_next and cpumask_first. smp_mpic_message_pass was doing open coded cpumask manipulation and passing an int for a cpumask into mpic_send_ipi. Since mpic_send_ipi is only used locally, make it static and convert it to take a cpumask. This allows us to clean up the mess in smp_mpic_message_pass.

Here the possible values of "reset_type": 1 - PPC4xx core reset 2 - PPC4xx chip reset 3 - PPC4xx system reset (default) This will be used by a new PPC440SPe board port, which needs a "chip reset" instead of the default "system reset" to be asserted.

If CPM_CLK_RTX has been used for the parameter mode, the clock has been configured only for TX but not for RX. With this patch CPM_CLK_RTX configures the clock for both directions correctly.

* | of: Remove duplicate fields from of_platform_driverGrant Likely2010-05-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | .name, .match_table and .owner are duplicated in both of_platform_driver and device_driver. This patch is a removes the extra copies from struct of_platform_driver and converts all users to the device_driver members. This patch is a pretty mechanical change. The usage model doesn't change and if any drivers have been missed, or if anything has been fixed up incorrectly, then it will fail with a compile time error, and the fixup will be trivial. This patch looks big and scary because it touches so many files, but it should be pretty safe.
