| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Using the added infrastructure for handling SoC differences, this commit adds support for the watchdog controller available in Armada 370 and Armada XP SoCs. Also, and because the AXP clock initialization uses of_clk_get_by_name, this commit changes the orion clock initialization to use clk_get() and adds a proper clk_put() on the common exit/error paths.

| * watchdog: orion: Handle the interrupt so it's properly ackedEzequiel Garcia2014-02-21
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DT-enabled plaforms, where the irqchip driver for the brigde interrupt controller is available, can handle the watchdog IRQ properly. Therefore, request the interrupt and add a dummy handler that merely calls panic(). This is done in order to have an initial 'ack' of the interruption, which clears the watchdog state. Furthermore, since some platforms don't have such IRQ, this commit makes the interrupt specification optional.
