This patche set removes dependency on the following config
option in musb driver:
CONFIG_USB_MUSB_OMAP2PLUS
CONFIG_USB_MUSB_TUSB6010
CONFIG_USB_MUSB_AM35X
CONFIG_USB_MUSB_DAVINCI
CONFIG_USB_MUSB_DA8XX
CONFIG_USB_MUSB_UX500
also removes the dma controller related config options below from
musb source code, and only keep very few of them in header file:
CONFIG_USB_INVENTRA_DMA
CONFIG_USB_TUSB_OMAP_DMA
CONFIG_USB_TI_CPPI_DMA
so musb driver source code is more clean than before, :-).
The patch set makes full use of the hw glue layer implemented
by Felipe.
Since all the specific hardwares' related option are removed,
we can build one single musb driver(binary) to make it working
on multiple machines of same ARCH.
Also the patches support the features below:
- each glue driver can be compiled as one standalone module
- each dma controler driver can be compiler as one standalone module
The patch set has been tested on beagle xM, g_ether/g_zero in gadget
mode are OK and mass storage/usb hub function in host mode are OK even both
OMAP2PLUS, TUSB6010 and AM35X are enabled and the three modules are
built in one image at the same time.
The patch set is against 2.6.37-rc6-next-20101217 plus the musb fix patch
with title below:
usb: musb: fix kernel panic during s2ram(v2)
v2:
- fix musb_platform_get_hw_revision reported by Felipe
- coding style fix reported by Sergei
- fix dma controller name reported by Sergei and Felipe
- define is_inventra_dma/is_cppi_enabled/tusb_dma_omap in
musb_dma.h, reported by Sergei and Felipe
Thanks Sergei and Felipe.
v1:
- export symbols as GPL
- UX500 cleanup
- sync with -next tree
- other suggestions from Felipe
I applied these to musb-next branch. I can still take changes to those
patches, of course, but it's easier if people want to test.
