2013-04-11bus: mvebu: fix mistake in PCIe window target attribute for KirkwoodThomas Petazzoni
The target and attributes for the PCIe address decoding windows were not correct on Kirkwood for the second PCIe interface. Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.com> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
2013-03-30bus: mvebu-mbus: Restore checking for coherency fabric hardwareNeil Greatorex
The new mvebu-mbus driver was not checking the device tree for coherency fabric hardware and hence was not setting the hw_io_coherency flag in mbus_state. This prevented the mvsdio driver from operating correctly. This patch restores the check. Signed-off-by: Neil Greatorex <neil@fatboyfat.co.uk> Signed-off-by: Jason Cooper <jason@lakedaemon.net>
2013-03-28bus: introduce an Marvell EBU MBus driverThomas Petazzoni
The Marvell EBU SoCs have a configurable physical address space layout: the physical ranges of memory used to address PCI(e) interfaces, NOR flashes, SRAM and various other types of memory are configurable by software, through a mechanism of so-called 'address decoding windows'. This new driver mvebu-mbus consolidates the existing code to address the configuration of these memory ranges, which is spread into mach-mvebu, mach-orion5x, mach-mv78xx0, mach-dove and mach-kirkwood. Following patches convert each Marvell EBU SoC family to use this driver, therefore removing the old code that was configuring the address decoding windows. It is worth mentioning that the MVEBU_MBUS Kconfig option is intentionally added as a blind option. The new driver implements and exports the mv_mbus_dram_info() function, which is used by various Marvell drivers throughout the tree to get access to window configuration parameters that they require. This function is also implemented in arch/arm/plat-orion/addr-map.c, which ultimately gets removed at the end of this patch series. So, in order to preserve bisectability, we want to ensure that *either* this new driver, *or* the legacy code in plat-orion/addr-map.c gets compiled in. By making MVEBU_MBUS a blind option, we are sure that only a platform that does 'select MVEBU_MBUS' will get this new driver compiled in. Therefore, throughout the next patches that convert the Marvell sub-architectures one after the other to this new driver, we add the 'select MVEBU_MBUS' and also ensure to remove plat-orion/addr-map.c from the build for this specific sub-architecture. This ensures that bisectability is preserved. Ealier versions of this driver had a DT binding, but since those were not yet agreed upon, they were removed. The driver still uses of_device_id to find the SoC specific details according to the string passed to mvebu_mbus_init(). The plan is to re-introduce a proper DT binding as a followup set of patches.

2013-01-03Drivers: misc: remove __dev* attributes.Greg Kroah-Hartman
CONFIG_HOTPLUG is going away as an option. As a result, the __dev* markings need to be removed. This change removes the use of __devinit, __devexit_p, __devinitdata, __devinitconst, and __devexit from these drivers. Based on patches originally written by Bill Pemberton, but redone by me in order to handle some of the coding style issues better, by hand.

2012-12-16ARM: OMAP: Fix drivers to depend on omap for internal devicesTony Lindgren
These devices are not available on other architectures, so let's limit them to omap. If the driver subsystem maintainers want to build test system wide changes without building for each target, it's easy to carry a test patch that just strips out the depends entries from Kconfig files.

2012-11-07drivers: bus: ocp2scp: add pdata supportKishon Vijay Abraham I
ocp2scp was not having pdata support which makes *musb* fail for non-dt boot in OMAP platform. The pdata will have information about the devices that is connected to ocp2scp. ocp2scp driver will now make use of this information to create the devices that is attached to ocp2scp. This is needed to fix MUSB regression caused by commit c9e4412a (arm: omap: phy: remove unused functions from omap-phy-internal.c) Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Acked-by: Felipe Balbi <balbi@ti.com> [tony@atomide.com: updated comments for regression info] Signed-off-by: Tony Lindgren <tony@atomide.com>
2012-10-01drivers: bus: omap_l3: fixup merge conflict resolutionOlof Johansson
This fixes a local merge conflict resolution done wrong locally in arm-soc for-next. soc.h was added on a cleanup branch, but the driver was moved and the header no longer needed.
