Couple of points worth mentioning: * The earlyprintk portion of driver still relies on static platform data we would need some earlyprintk handling in of_fdt_* to clean it up properly * Two of the three platform data instances are now retrieved from DT. However one still needs to be dynamically passed by platform (using of_dev_auxdata) as we want to run same image in simulator and hardware Tested on in-works ARC 3.8 port. P.S. Greg, can this be treated as a bug-fix for 3.8 Thx, -Vineet Vineet Gupta (4): serial/arc-uart: Don't index with -ve platform_device->id serial/arc-uart: split probe from probe_earlyprintk serial/arc-uart: platform_data order changed serial/arc-uart: switch to devicetree based probing .../devicetree/bindings/tty/serial/arc-uart.txt | 26 ++++++ drivers/tty/serial/arc_uart.c | 95 ++++++++++++++------ 2 files changed, 94 insertions(+), 27 deletions(-) create mode 100644 Documentation/devicetree/bindings/tty/serial/arc-uart.txt -- 1.7.4.1
