Subject: [PATCH v4 5/7] Watchdog: introduce ARM SBSA watchdog driver
Date: Tue, 2 Jun 2015 12:05:05 +0800 [thread overview]
Message-ID: <1433217907-928-6-git-send-email-fu.wei@linaro.org> (raw)
In-Reply-To: <1433217907-928-1-git-send-email-fu.wei@linaro.org>
From: Fu Wei <fu.wei@linaro.org>
This driver bases on linux kernel watchdog framework, and
use "pretimeout" in the framework. It supports getting timeout and
pretimeout from parameter and FDT at the driver init stage.
In first timeout, the interrupt routine run panic to save
system context.

+ * Note: This SBSA Generic watchdog driver is compatible with
+ * the pretimeout concept of Linux kernel.
+ * The timeout and pretimeout are set by the different REGs.
+ * The first watch period is set by writing WCV directly,
+ * that can support more than 10s timeout at the maximum
+ * system counter frequency.
+ * The second watch period is set by WOR(32bit) which will be loaded
+ * automatically by hardware, when WS0 is triggered.
+ * This gives a maximum watch period of around 10s at the maximum
+ * system counter frequency.
+ * The System Counter shall run at maximum of 400MHz.
+ * More details: ARM DEN0029B - Server Base System Architecture (SBSA)
+ *
+ * Kernel/API: P---------| pretimeout
+ * |-------------------------------T timeout
+ * SBSA GWDT: P--WOR---WS1 pretimeout
+ * |-------WCV----------WS0~~~~~~~~T timeout
