2014-02-21xtensa: xtfpga: set ethoc clock frequencyMax Filippov1-0/+1
Connect xtfpga board ethernet MAC to the clock in the DTS. Set up MAC base frequency in the platform data in case of build w/o CONFIG_OF. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2014-02-21xtensa: xtfpga: use common clock frameworkMax Filippov1-3/+8
With this change the board needs to set up single clock object, users of this clock will get correct frequency automatically. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2014-01-15xtensa: standardize devicetree cpu compatible stringsBaruch Siach3-4/+4
The recommended compatible string format, according to the ePAPR v1.1 standard, is "manufacturer,model". Change the xtensa cpu compatible strings to "cdns,xtensa-cpu". Also, change the boards compatible strings in a similar way. The pic compatible string will be dealt with in a separate patch.

2014-01-14xtensa: move built-in PIC to drivers/irqchipMax Filippov1-1/+1
Extract xtensa built-in interrupt controller implementation from xtensa/kernel/irq.c and move it to other irqchips, providing way to instantiate it from the device tree. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com> Signed-off-by: Chris Zankel <chris@zankel.net>
2013-02-23xtensa: use new common dtc ruleStephen Warren1-0/+15
The current rules have the .dtb files build in a different directory from the .dts files. This patch changes xtensa to use the generic dtb rule which builds .dtb files in the same directory as the source .dts. This requires moving parts of arch/xtensa/boot/Makefile into newly created arch/xtensa/boot/dts/Makefile, and updating arch/xtensa/Makefile to call the new Makefile.
