Detects RIO link to the already enumerated device and properly sets links between device objects. Changes to the enumeration/discovery logic: 1. Use Master Enable bit to signal end of the enumeration - agents may start their discovery process as soon as they see this bit set (Component Tag register was used before for this purpose). 2. Enumerator sets Component Tag (!= 0) immediately during device setup. This allows to identify the device if the redundant route exists in a RIO system.

Replace FSL USB platform code by simple platform driver for creation of FSL USB platform devices. The driver creates platform devices based on the information from USB nodes in the flat device tree. This is the replacement for old arch fsl_soc usb code removed by this patch. The driver uses usual of-style binding, available EHCI-HCD and UDC drivers can be bound to the created devices. The new of-style driver additionaly instantiates USB OTG platform device, as the appropriate USB OTG driver will be added soon.

MPC5121 DIU configuration/setup as initialized by the boot loader currently will get lost while booting Linux. As a result displaying the boot splash is not possible through the boot process. To prevent this we reserve configured DIU frame buffer address range while booting and preserve AOI descriptor and gamma table so that DIU continues displaying through the whole boot process. On first open from user space DIU frame buffer driver releases the reserved frame buffer area and continues to operate as usual.

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: NGrant Likely <grant.likely@secretlab.ca> Acked-by: NDavid S.

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.
