Hi Greg, Here are explanations of the two patches:
0001-sc16is7xx-fix-RTS-CTS-implementation.patch: RTS/CTS handshaking for sc16is7xx driver does not work, no character is sent regardless of the state of CTS. This test was done on a raspberry pi 2: 1- sc16is7xx_set_baud() overwrites the flow control configuration bits in EFR. Writing in EFR has been replaced by an update. 2- As noted in the file Documentation/serial/driver, get_mctrl() should return an active state for unsupported entries. 0002-sc16is7xx-add-reading-CTS.patch: This patch adds the possibility to read the actual status of the CTS input when RTS/CTS handshaking is not activated. After those changes everything works. Thank you for your hard work. Have a nice day. Pascal
