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 Signed-off-by: Felipe Balbi Signed-off-by: Sasha Levin Signed-off-by: Greg Kroah-Hartman --- drivers/usb/dwc3/core.h | 2 ++ 1 file changed, 2 insertions(+) diff --git a/drivers/usb/dwc3/core.h b/drivers/usb/dwc3/core.h index 94d6a3e2ad97..affb3d757310 100644 --- a/drivers/usb/dwc3/core.h +++ b/drivers/usb/dwc3/core.h @@ -238,6 +238,8 @@ #define DWC3_GUSB3PIPECTL_TX_DEEPH(n) ((n) << 1) /* Global TX Fifo Size Register */ +#define DWC31_GTXFIFOSIZ_TXFRAMNUM BIT(15) /* DWC_usb31 only */ +#define DWC31_GTXFIFOSIZ_TXFDEF(n) ((n) & 0x7fff) /* DWC_usb31 only */ #define DWC3_GTXFIFOSIZ_TXFDEF(n) ((n) & 0xffff) #define DWC3_GTXFIFOSIZ_TXFSTADDR(n) ((n) & 0xffff0000) -- 2.20.1
