* usb: musb: Make busctl_offset an io-op rather then a defineHans de Goede2015-05-261-0/+2
| | | | | | | | | | | The Allwinner (sunxi) implementation of the musb has its busctl registers indexed by the MUSB_INDEX register rather then in a flat address space. This commit turns MUSB_BUSCTL_OFFSET from a macro into an io-op which can be overridden from the platform ops.

* usb: musb: Add function pointers for IO access functionsTony Lindgren2014-11-251-0/+18
| | | | | | | | | | | | | | | | | | | MUSB currently breaks badly if we try to build in support for multiple platforms. This also happens if done as loadable modules, which is not nice for distros. Let's fix the issue by adding new struct musb_io for the IO access functions that the platform code can populate. Note that we don't want to use the current ops as that's really platform_data and and set as a const. This should allow eventually adding function pointers also for the DMA code to struct musb_io, but that's a whole different set of patches. For now, let's just fix the PIO access.

* usb: musb: use io{read,write}*_rep accessorsMatthew Leach2012-12-181-21/+0
| | | | | | | | | | | | | | | | | The {read,write}s{b,w,l} operations are not defined by all architectures and are being removed from the asm-generic/io.h interface. This patch replaces the usage of these string functions in the musb accessors with io{read,write}{8,16,32}_rep calls instead.

* m68k: Make sure {read,write}s[bwl]() are always definedGeert Uytterhoeven2012-04-221-1/+1
| | | | | | | | | | | | | | drivers/usb/musb/musb_io.h provides default implementations for {read,write}s[bwl]() on most platforms, some of which will conflict soon with platform-specific counterparts on m68k. To avoid having to add more platform-specific checks to musb_io.h later, make sure {read,write}s[bwl]() are always defined on m68k, and disable the default implementations in musb_io.h on m68k, like is already done for several other architectures.

* usb: musb: allow building USB_MUSB_TUSB6010 as a moduleArnd Bergmann2011-12-121-1/+1
| | | | | | | | | | | | | Commit 1376d92f9 "usb: musb: allow musb and glue layers to be modules" made the USB_MUSB_TUSB6010 option modular, but actually building the driver as a module does not work, so various randconfig builds actually fail. This changes all code that depends on the option to also check for modular builds, and exports the necessary symbols.

* musb: io: only define read/write stubs if they're not defined yetFelipe Balbi2008-10-171-1/+3
| | | | | | | | | | | | | | | For those archs which don't provide read/write friends we provide our own implementation so musb driver won't break compilation. This is temporary fix until a better solution comes from upstream. Idealy, <linux/io.h> would provide those calls if the architecture did not provide them yet. In that case being possible to remove all those stubs from musb_io.h Signed-off-by: Felipe Balbi <felipe.balbi@nokia.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
