2015-04-29usb: dwc2: gadget: powerup controller if neededGregory Herrero1-0/+9
During vbus session, usb controller needs to exit hibernation if it was previously in suspend state. Since controller will be resetted and configured, there is no need to restore registers. Moreover, set lx_state to L0 on B session. vbus_session callback may not be used by all platforms. Thus, controller software state needs to be set to L0 if the controller detects a valid B session. Otherwise, lx_state will remain L2 and prevent any request submission.

2015-02-04usb: dwc2: Fix a bug in reading the endpoint directions from reg.Roshan Pius1-1/+1
According to the DWC2 datasheet, the HWCFG1 register stores the configured endpoint directions for endpoints 0-15 in bit positions 0-31. ========================== Endpoint Direction (EpDir) This 32-bit field uses two bits per endpoint to determine the endpoint direction. Endpoint Bits [31:30]: Endpoint 15 direction Bits [29:28]: Endpoint 14 direction .... Bits [3:2]: Endpoint 1 direction Bits[1:0]: Endpoint 0 direction (always BIDIR) ========================== The DWC2 driver is currently interpreting the contents of the register as directions for endpoints 1-15 which leads to an error in determining the configured endpoint directions in the core because the first 2 bits determine the direction of endpoint 0 and not 1. This is based on testing/next branch in Felipe's git. Signed-off-by: Roshan Pius <rpius@chromium.org> Acked-by: John Youn <johnyoun@synopsys.com> Signed-off-by: Felipe Balbi <balbi@ti.com>
