[PATCH 0/3] watchdog: sbsa_gwdt: add support for Marvell ac5

[Elad Nachman <enachman@marvell.com>]

From: Elad Nachman <enachman@marvell.com>

Add support for Marvell ac5/x variant of the ARM
sbsa global watchdog. This watchdog deviates from
the standard driver by the following items:

1. Registers reside in secure register section.
   hence access is only possible via SMC calls to ATF.

2. There are couple more registers which reside in
   other register areas, which needs to be configured
   in order for the watchdog to properly generate
   reset through the SOC.

   The new Marvell compatibility string differentiates between
   the original sbsa mode of operation and the Marvell mode of
   operation.
