2016-08-30usb: musb: Fix locking errors for host only modeTony Lindgren1-1/+6
If we have USB gadgets disabled and USB_MUSB_HOST set, we get errors "possible irq lock inverssion dependency detected" errors during boot. Let's fix the issue by adding start_musb flag and start the controller after we're out of the spinlock protected section.

The default_length parameter of alloc_ep_req was not really necessary and gadget drivers would almost always create an inline function to pass the same value to len and default_len. This patch removes that parameter and updates all calls to alloc_ep_req() to use the new API. Signed-off-by: Felipe F.

2016-08-25usb: dwc3: Add ENDXFER command pollingJohn Youn3-1/+30
ENDXFER polling is available on version 3.10a and later of the DWC_usb3 (USB 3.0) controller. With this feature, the software can poll the CMDACT bit in the DEPCMD register after issuing an ENDXFER command. This feature is enabled by writing GUCTL2[14]. This feature is NOT available on the DWC_usb31 (USB 3.1) IP. Signed-off-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
2016-08-25usb: phy: mxs: Add DT bindings to configure TX settingsJaret Cantu1-0/+61
The TX settings can be calibrated for particular hardware. The phy is reset by Linux, so this cannot be handled by the bootloader. The TRM mentions that the maximum resistance should be used for the DN/DP calibration in order to pass USB certification. The values for the TX registers are poorly described in the TRM. The meanings of the register values were taken from another NXP-provided document: https://community.nxp.com/message/566147#comment-566912 Acked-by: Peter Chen <peter.chen@nxp.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Jaret Cantu <jaret.cantu@timesys.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com>
