<id>7a21b27aafa3edead79ed97e6f22236be6b9f447</id>
<content type='text'>
Patch modifies the TD_SIZE in TRB before ZLP TRB.
The TD_SIZE in TRB before ZLP TRB must be set to 1 to force
processing ZLP TRB by controller.

Until the endpoint is disabled, its descriptors should remain valid.
When its requests are removed from ep disable, the request completion
routine may attempt to access the endpoint's descriptor. Don't clear the
descriptors before that.

During handling Clear Halt Endpoint Feature request, driver invokes
Reset Endpoint command. Because this command has some issue with
transition endpoint from Running to Idle state the driver must
stop the endpoint by using Stop Endpoint command.

If there's a disconnection while operating in eSS, there may be a delay
in VBUS drop response from the connector. In that case, the internal
link state may drop to operate in usb2 speed while the controller thinks
the VBUS is still high. The driver must make sure to disable
GUSB2PHYCFG.SUSPHY when sending endpoint command while in usb2 speed.
The End Transfer command may be called, and only that command needs to
go through at this point. Let's keep it simple and unconditionally
disable GUSB2PHYCFG.SUSPHY whenever we issue the command.

This scenario is not seen in real hardware. In a rare case, our
prototype type-c controller/interface may have a slow response
triggerring this issue.

Add LARA-L6 PIDs for three different USB compositions.

LARA-L6 module can be configured (by AT interface) in three different
USB modes:
* Default mode (Vendor ID: 0x1546 Product ID: 0x1341) with 4 serial
interfaces
* RmNet mode (Vendor ID: 0x1546 Product ID: 0x1342) with 4 serial
interfaces and 1 RmNet virtual network interface
* CDC-ECM mode (Vendor ID: 0x1546 Product ID: 0x1343) with 4 serial
interface and 1 CDC-ECM virtual network interface

In default mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic
If 1: AT parser
If 2: AT parser
If 3: AT parser/alternative functions

In RmNet mode LARA-L6 exposes the following interfaces:
If 0: Diagnostic

Remove the UBLOX_PRODUCT_R6XX 0x90fa association since LARA-R6 00B final
product uses a new USB composition with different PID. 0x90fa PID used
only by LARA-R6 internal prototypes.

Move 0x90fa PID directly in the option_ids array since used by other
Qualcomm based modem vendors as pointed out in:
