2012-10-02Merge tag 'multiplatform' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc Pull ARM soc multiplatform enablement from Olof Johansson: "This is a pretty significant branch. It's the introduction of the first multiplatform support on ARM, and with this (and the later branch) merged, it is now possible to build one kernel that contains support for highbank, vexpress, mvebu, socfpga, and picoxcell. More platforms will be convered over in the next few releases. Two critical last things had to be done for this to be practical and possible: * Today each platform has its own include directory under mach-<mach>/include/mach/*, and traditionally that is where a lot of driver/platform shared definitions have gone, such as platform data structures. They now need to move out to a common location instead, and this branch moves a large number of those out to include/linux/platform_data. * Each platform used to list the device trees to compile for its boards in mach-<mach>/Makefile.boot. Both of the above changes will mean that there are some merge conflicts to come (and some to resolve here). It's a one-time move and once it settles in, we should be good for quite a while. Sorry for the overhead." Fix conflicts as per Olof. * tag 'multiplatform' of git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc: (51 commits) ARM: add v7 multi-platform defconfig ARM: msm: Move core.h contents into common.h ARM: highbank: call highbank_pm_init from .init_machine ARM: dtb: move all dtb targets to common Makefile ARM: spear: move platform_data definitions ARM: samsung: move platform_data definitions ARM: orion: move platform_data definitions ARM: vexpress: convert to multi-platform ARM: initial multiplatform support ARM: mvebu: move armada-370-xp.h in mach dir ARM: vexpress: remove dependency on mach/* headers ARM: picoxcell: remove dependency on mach/* headers ARM: move all dtb targets out of Makefile.boot ARM: picoxcell: move debug macros to include/debug ARM: socfpga: move debug macros to include/debug ARM: mvebu: move debug macros to include/debug ARM: vexpress: move debug macros to include/debug ARM: highbank: move debug macros to include/debug ARM: move debug macros to common location ARM: make mach/gpio.h headers optional ...

Platform data for device drivers should be defined in include/linux/platform_data/*.h, not in the architecture and platform specific directories.

2012-09-11Merge tag 'musb-for-v3.7' of ↵Greg Kroah-Hartman
git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next usb: musb: patches for v3.7 merge window Here we have a bunch of miscellaneous cleanups and fixes to the musb driver. It fixes a bunch of mistakes errors which nobody has triggered before, so I'm not Ccing stable tree. We are finally improving OMAP's VBUS/ID Mailbox usage so that we can introduce our PHY drivers properly. Also, we're adding support for multiple instances of the MUSB IP in the same SoC, as seen on some platforms from TI which have 2 MUSB instances. Other than that, we have some small fixes like not kicking DMA for a zero byte transfer, or properly handling NAK timeout on MUSB's host side, and the enabling of DMA Mode1 for any transfers which are aligned to wMaxPacketSize. All patches have been pending on mailing list for a long time and I don't expect any big surprises with this pull request.

usb_get_phy will return -ENODEV if it's not able to find the phy.

2012-06-25usb: otg: support for multiple transceivers by a single controllerKishon Vijay Abraham I
Add a linked list for keeping multiple PHY instances with different types so that we can have separate USB2 and USB3 PHYs on one single board. _get_phy_ has been changed so that the controller gets the transceiver by type. _remove_phy_ has been added to let the phy be removed from the phy list.

git://git.kernel.org/pub/scm/linux/kernel/git/balbi/usb into usb-next USB: transceiver changes for 3.4 Here we have a big rework done by Heikki Krogerus (thanks) which splits OTG functionality away from transceivers. We have known for quite a long time that struct otg_transceiver was a bad name for the structure, considering transceiver is far from being OTG-specific (see 4e67185).

2012-01-31usb: musb: make modules behave betterFelipe Balbi
There's really no point in doing all that initcall trickery when we can safely let udev handle module probing for us. Remove all of that trickery, by moving everybody to module_init() and making proper use of platform_device_register() rather than platform_device_probe().

2011-11-14usb: musb: fix compilation breakage introduced by de47725Felipe Balbi
commit de47725 (include: replace linux/module.h with "struct module" wherever possible) introduced a compilation breaked when it removed <linux/module.h> from <linux/device.h> which musb glue layers were (mistakenly) relying on. Include that header to fix the compile error. Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
2011-07-01usb: musb: drop a gigantic amount of ifdeferryFelipe Balbi
the MUSB IP is always OTG, so there's no point in adding so many ifdefs on the code. Drop those and always compile the driver for OTG support. This also allows us to drop the useless "driver mode" choice. For doing that, we need to make musb depend on both Host and Peripheral side.

2011-05-13usb: musb: drop unneeded musb_debug trickeryFelipe Balbi
We have a generic way of enabling/disabling different debug messages on a driver called DYNAMIC_PRINTK. Anyone interested in enabling just part of the debug messages, please read the documentation under: Documentation/dynamic-debug-howto.txt for information on how to use that great infrastructure.

2011-05-07usb: fix building musb driversAnatolij Gustschin
Commit 3dacdf11 "usb: factor out state_string() on otg drivers" broke building musb drivers since there is already another otg_state_string() function in musb drivers, but with different prototype. Fix musb drivers to use common otg_state_string(), too. Also provide a nop for otg_state_string() if CONFIG_USB_OTG_UTILS is not defined.

2010-12-10usb: musb: split da8xx to its own platform_driverFelipe Balbi

2010-12-07usb: musb: make all glue layer export struct musb_platform_opsFelipe Balbi
preparing to a big refactor on musb code. We need to be able to compile in all glue layers (or at least all ARM-based ones) together and have a working binary. While preparing for that, we move every glue layer to export only one symbol, which is a struct musb_platform_ops, and make all other functions static. Later patches will come to allow for compiling all glue layers together and have a working binary. Signed-off-by: Felipe Balbi <balbi@ti.com>
