Here's a new patchset adding support for watchdog on Armada 375 and Armada 38x SoCs. Regarding the previous patchset, this time we're handling the SoCs differences in the watchdog driver itself.
The new Armada 375/385 SoCs have two registers for the watchdog RSTOUT: 1. It has a dedicated register (similar to the one in A370/XP) 2. Also has a bit in a shared RSTOUT register. Therefore, in order to support this two-folded RSTOUT, we extend the 'reg' property in the watchdog devicetree and require a new pair of cells to specify the shared RSTOUT. On the driver side, we need to implement per-SoC stop() and enabled() functions. Such somewhat complex infrastructure is needed to ensure the driver performs proper reset of the watchdog timer, by masking and disabling the RSTOUT before the interrupt is enabled. Changes from v1: * Reworked entirely!
