| |
From: Magnus Damm <damm@opensource.se>
Add support for SCIF2 port3 pin functions SCK, TXD and RXD to the r7s72100 PINCTRL code. There are two possible pins that can be used for TXD (Port 3 Pin 0 Function 6 and Port 3 Pin 1 Function 4) and because of that are the data pins broken out in separate TXD and RXD.
This format is similar to other sh-pfc code, but a following patch converts this to less verbose and less readable code.
