usb: dwc3: Update DWC_usb31 GTXFIFOSIZ reg fields
[ Upstream commit 0cab8d26d6e5e053b2bed3356992aaa71dc93628 ] Update two GTXFIFOSIZ bit fields for the DWC_usb31 controller. TXFDEP is a 15-bit value instead of 16-bit value, and bit 15 is TXFRAMNUM. The GTXFIFOSIZ register for DWC_usb31 is as follows: +-------+-----------+----------------------------------+ | BITS | Name | Description | +=======+===========+==================================+ | 31:16 | TXFSTADDR | Transmit FIFOn RAM Start Address | | 15 | TXFRAMNUM | Asynchronous/Periodic TXFIFO | | 14:0 | TXFDEP | TXFIFO Depth | +-------+-----------+----------------------------------+ Signed-off-by: Thinh Nguyen <thinhn@synopsys.com> Signed-off-by: Felipe Balbi <felipe.balbi@linux.intel.com> Signed-off-by: Sasha Levin <alexander.levin@microsoft.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
