* usb: musb: drop unneeded musb_debug trickeryFelipe Balbi2011-05-131-5/+5
| | | | | | | | | | | | | | | 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.

* usb: fix building musb driversAnatolij Gustschin2011-05-061-4/+7
| | | | | | | | | | | | | 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.

* musb: am35x: fix compile error due to control apisAjay Kumar Gupta2010-12-101-85/+45
| | | | | | | | | | | | commit 4814ced5116e3b73dc4f63eec84999739fc8ed11 (OMAP: control: move plat-omap/control.h to mach-omap2/control.h) moved <plat/control.h> to another location, preventing drivers from accessing it, so we need to pass function pointers from arch code to be able to talk to internal PHY on AM35x.

* usb: musb: drop board_set_vbusFelipe Balbi2010-12-101-2/+0
| | | | | | that's not used anymore. So let's drop it. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: am35x: usb dev_pm_ops structureFelipe Balbi2010-12-101-17/+45
| | | | | | | | | instead of using musb_platform_suspend_resume, we can use dev_pm_ops and let platform_device core handle when to call musb_core's suspend and glue layer's suspend. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: drop musb_platform_save/restore_contextFelipe Balbi2010-12-101-6/+9
| | | | | | | ... that can be easily folded into the musb_platform_suspend/resume calls. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: move clock handling to glue layerFelipe Balbi2010-12-101-34/+57
| | | | | | | | | musb core doesn't need to know about platform specific details. So start moving clock handling to platform glue layer and make musb core agnostic about that. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: pass platform_ops via platform_dataFelipe Balbi2010-12-101-1/+3
| | | | | | | ... then we don't need to export any symbols from glue layer to musb_core. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: am35x: give it a context structureFelipe Balbi2010-12-101-9/+28
| | | | | | | | | | that structure currently only holds a device pointer to our own platform_device and musb's platform_device, but soon it will hold pointers to our clock structures and glue-specific bits and pieces. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: split am35x to its own platform_driverFelipe Balbi2010-12-101-0/+84
| | | | | | | | | | | Just adding its own platform_driver, not really using it yet. When all HW glue layers are converted, more patches will come to split power management code from musb_core and move it completely to HW glue layer. Signed-off-by: Felipe Balbi <balbi@ti.com>
* usb: musb: make all glue layer export struct musb_platform_opsFelipe Balbi2010-12-071-12/+25
| | | | | | | | | | | | | | | | | | 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>
* USB: musb: AM35x: Workaround for fifo read issueAjay Kumar Gupta2010-10-221-0/+30
| | | | | | | | | | AM35x supports only 32bit read operations so we need to have workaround for 8bit and 16bit read operations. Signed-off-by: Ajay Kumar Gupta <ajay.gupta@ti.com> Signed-off-by: Felipe Balbi <balbi@ti.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* USB: musb: add musb support for AM35xAjay Kumar Gupta2010-10-221-0/+494
AM35x has musb interface and uses CPPI4.1 DMA engine. Current patch supports only PIO mode. DMA support can be added later once basic CPPI4.1 DMA patch is accepted. Also added USB_MUSB_AM35X which is required to differentiate musb ips between OMAP3x and AM35x. This config would be used to for below purposes, - Select am35x.c instead of omap2430.c for compilation at drivers/usb/musb directory. Please note there are significant differneces in these two files as musb ip in quite different on AM35x. Please note that in multi omap configuration only omap2430.c file will get compiled and we would require to select only AM35x based board config to compile am35x.c - Select workaround codes applicable for AM35x musb issues. one such workaround is for bytewise read issue on AM35x.
