[PATCH v3 0/6] DT support for AT91RM9200

[Joachim Eastwood]

Patch 1 is a fix for a build failure which can happen if board-dt is enabled when no AT91SAM machines are enabled.

Patch 2 adds DT support to the AT91RM9200 system timer. Based on AT91 PIT patch by Jean-Christophe PLAGNIOL-VILLARD.

Patch 3 adds clock lookups for DT.

Patch 4 adds a new board for RM9200 DT support.

Patch 5-6 adds the base devicetree for AT91RM9200 and support for AT91RM9200-EK board.


I don't have a AT91RM9200-EK to test on but I was able to boot at91rm9200ek.dts on my custom board using a initrd. As far as I can tell pinctrl, usart and ohci all work.

Patches based on linux-next.
