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.

2010-12-10usb: musb: drop musb_platform_suspend/resumeFelipe Balbi2-25/+0
all glue layers are now fully moved to the new setup. We are now using dev_pm_ops to implement suspend/resume functionality and thus, musb_platform_suspend/resume has become deprecated and useless. This patch drops those function pointers and its uses. Signed-off-by: Felipe Balbi <balbi@ti.com>

2010-12-07usb: musb: make all glue layer export struct musb_platform_opsFelipe Balbi9-177/+335
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>
2010-12-07usb: musb: introduce struct musb_platform_opsFelipe Balbi1-0/+28
This will be passed to musb_core by platform glue layer in order to make it easier to compile support for several HW glue layers. Later patches will come using this structure and also moving HW glue layers to its own platform driver; the idea is to be able to handle platform peculiarities in a manner which doesn't affect one another.

2010-12-01usb: musb: add names for IRQs in structure resourceHema Kalliguddi10-3/+17
Soon resource data will get automatically populated from a set of autogenerated data from TI's hardware database for the OMAP platform. Such database, might not have resources at the expected order by the current drivers. While we could hack in some exceptions to that tool to generate resources in a specific order, it seems less fragile to use the resource name instead. That way, no matter what order the resources are generated, the driver still work. Modified the OMAP, Blackfin and Davinci architecture files to add the name of the IRQs in the resource structures and musb driver to use the platform_get_irq_byname() api to get the device and dma irq numbers instead of using the index.

Function twl4030_usb_remove can cause unbalanced regulator disables in twl4030_phy_power if the cable is not connected. Regulator enable/disable calls are in balance only if the twl4030_phy_resume was called prior the twl4030_usb_remove, that is, the cable was connected. Fix this by checking the 'asleep' variable in twl4030_usb_remove since that variable is used to check state in other functions.

2010-11-30usb-wwan: implement TIOCGSERIAL and TIOCSSERIAL to avoid blocking close(2)Dan Williams3-0/+81
Some devices (ex ZTE 2726) simply don't respond at all when data is sent to some of their USB interfaces. The data gets stuck in the TTYs queue and sits there until close(2), which them blocks because closing_wait defaults to 30 seconds (even though the fd is O_NONBLOCK). This is rarely desired. Implement the standard mechanism to adjust closing_wait and let applications handle it how they want to. Signed-off-by: Dan Williams <dcbw@redhat.com>
