| * musb: sunxi: Make sunxi musb glue work without MUSB_PIO_ONLYHans de Goede2015-10-091-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | Now that it is possible to build in multiple dma engines, we can no longer require MUSB_PIO_ONLY to be set when using the sunxi musb glue. This patch adds dummy dma hooks to make the musb glue work without MUSB_PIO_ONLY. This hooks are fake because we do not support dma with musb on sunxi. The Allwinnner Android kernels have some dma code, but it is disabled as Allwinner never managed to get it to work.

* | usb: musb: omap2430: Fix regression caused by driver core changeTony Lindgren2015-10-281-6/+23
|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Commit ddef08dd00f5 ("Driver core: wakeup the parent device before trying probe") started automatically ensuring the parent device is enabled when the child gets probed. This however caused a regression for MUSB omap2430 interface as the runtime PM for the parent device needs the child initialized to access the MUSB hardware registers. Let's delay the enabling of PM runtime for the parent until the child has been properly initialized as suggested in an earlier patch by Grygorii Strashko <grygorii.strashko@ti.com>. In addition to delaying pm_runtime_enable, we now also need to make sure the parent is enabled during omap2430_musb_init. We also want to propagate an error from omap2430_runtime_resume if struct musb is not initialized. Note that we use pm_runtime_put_noidle here for both the child and parent to prevent an extra runtime_suspend/resume cycle. Let's also add some comments to avoid confusion between the two different devices.

| | | | | | | | | | | | | | After a few iterations of start/stop UVC camera streaming, the streaming stops. This patch adds 250us delay in the cppi channel abort path to let cppi drain properly. Using 50us delay seems to be too aggressive, some webcams are still broken. 250us is the original value used in TI 3.2 kernel.

* usb: musb: ensure in peripheral mode when checking sessionBin Liu2015-09-141-0/+1
| | | | | | | | | | | | | | | The change ensures otg is not in a A- state when checking for VBUS in peripheral mode. musb_start() where VBUS checking is in can be called in many situations. One example is in babble recovery routine, in which otg is transitioning from A-HOST to A-WAIT-BCON, but VBUS discharge takes time, so musb->is_active could be set to 1 due to this improper checking, then it causes musb_bus_suspend() failed which leads to warning log message flooding.

This has been observed to cause enumeration issues after suspend/resume cycles with AM335x.
