ARM: 8773/1: amba: Export amba_bustype

2018-05-19T10:53:46Z

This patch is provided in the context of allowing the Coresight driver subsystem to be loaded as modules. Coresight uses amba_bus in its call to bus_find_device() in of_coresight_get_endpoint_device() when searching for a configurable endpoint device. This patch allows Coresight to reference amba_bustype when built as a module.

drivers: remove force dma flag from buses

2018-05-03T14:25:08Z

With each bus implementing its own DMA configuration callback, there is no need for bus to explicitly set the force_dma flag. Modify the of_dma_configure function to accept an input parameter which specifies if implicit DMA configuration is required when it is not described by the firmware.

dma-mapping: move dma configuration to bus infrastructure

2018-05-03T14:22:18Z

ACPI/OF support for configuration of DMA is a bus specific aspect, and thus should be configured by the bus. Introduces a 'dma_configure' bus method so that busses can control their DMA capabilities. Also update the PCI, Platform, ACPI and host1x buses to use the new method.

ARM: amba: Fix race condition with driver_override

2018-04-26T08:35:04Z

The driver_override implementation is susceptible to a race condition when different threads are reading vs storing a different driver override. Add locking to avoid this race condition. Cfr. commits 6265539776a0810b ("driver core: platform: fix race condition with driver_override") and 9561475db680f714 ("PCI: Fix race condition with driver_override").

ARM: amba: Make driver_override output consistent with other buses

2018-04-26T08:32:51Z

For AMBA devices with unconfigured driver override, the "driver_override" sysfs virtual file is empty, while it contains "(null)" for platform and PCI devices. Make AMBA consistent with other buses by dropping the test for a NULL pointer. Note that contrary to popular belief, sprintf() handles NULL pointers fine; they are printed as "(null)".
