Add RS485 control for Fintek F81504/508/512 F81504/508/512 can control their RTS with H/W mode. PCI configuration space for each port is 0x40 + idx * 8 + 7. When it set with 0x01, it's configured with RS232 mode. RTS is controlled by MCR. When it set with 0x11, it's configured with RS485 mode. RTS is controlled by H/W, RTS low with idle & RX, high with TX. When it set with 0x31, it's configured with RS485 mode. RTS is controlled by H/W, RTS high with idle & RX, low with TX. We will force 0x01 on pci_fintek_setup(). Signed-off-by: Peter Hung <hpeter+linux_kernel@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org> |
