This reworks the way SuperSpeed descriptors are added and instead of having a magic after full and high speed descriptors, it reworks the whole descriptors block to include a flags field which lists which descriptors are present and makes future extensions possible.

Allow userspace to pass SuperSpeed descriptors and handle them in the driver accordingly. This change doesn't modify existing desc_header and thereby keeps the ABI changes backward compatible i.e. existing userspace drivers compiled with old header (functionfs.h) would continue to work with the updated kernel.

commit 511f3c53 (usb: gadget: udc-core: fix a regression during gadget driver unbinding) introduced a crash when DEBUG is enabled. The debug trace in the atmel_usba_stop function made the assumption that the driver pointer passed in parameter was not NULL, but since the commit above, such assumption was no longer always true. This commit now uses the driver pointer stored in udc which fixes this issue.

We need this to keep PHY's power on or off during the system suspend mode. If we need to enable USB wakeup, then we must keep PHY's power being on during the system suspend mode. Otherwise, we need to keep PHY's power being off to save power. Signed-off-by: Peter Chen <peter.chen@freescale.com> Signed-off-by: Felipe Balbi <balbi@ti.com>

When we need the PHY can be waken up by external signals, we can call this API. Besides, we call mxs_phy_disconnect_line at this API to close the connection between USB PHY and controller, after that, the line state from controller is SE0. Once the PHY is out of power, without calling mxs_phy_disconnect_line, there are unknown wakeups due to dp/dm floating at device mode.

Two PHY bugs are fixed by IC logic, but these bits are not enabled by default, so we enable them at driver.

Reprogramming the DMA after tear down is initiated leads to warning. This is mainly seen with ISOCH since we do a delayed completion for ISOCH transfers.

Adapted dwc3 core to use the Generic PHY Framework. So for init, exit, power_on and power_off the following APIs are used phy_init(), phy_exit(), phy_power_on() and phy_power_off(). However using the old USB phy library wont be removed till the PHYs of all other SoC's using dwc3 core is adapted to the Generic PHY Framework.

Since PHYs for dwc3 is optional (not all SoCs having PHYs for DWC3 should be programmed), do not return from probe if the USB PHY library returns -ENODEV as that indicates the platform does not have a programmable PHY. While this can be considered as a temporary fix, a long term solution would be to add 'nop' PHY for platforms that does not have programmable PHY.

Paul Zimmerman authored
That argument will be used in later patches when we have working hibernation support. For now, always pass it as false. The idea of this patch is to decrease to size of following patches and slowly add hibernation building blocks to the gadget side of dwc3 so that it becomes very easy to review the actual hibernation code.

Revisions between 2.10a and 2.50a (included) have a known issue which may cause xHCI compliance tests to fail and/or quality issues with Isochronous transactions. Note that this issue only impacts certain configurations of those revisions, namely the ones which have clock gating enabled. The suggested workaround is to disable clock gating in known broken revisions, make sure HW LPM is disabled and set GCTL.SOFITPSYNC to 1. Signed-off-by: Felipe Balbi <balbi@ti.com>
