It looks like cover letter was missing... This patch series includes some code refactor and adds new device support for at91sam9_wdt driver.
Instead of add a new driver like Linux kernel, at91sam9_wdt driver is extended as new watchdog variant is similar to existing one, especially for the function subset used by u-boot. 1. Remove unused typedef and rename variables for readability. 2. Add SAMA5D4 compatible, it has the same watchdog as SAM9260 except a new lockout feature is added. Currently this feature is unimplemented. 3. SAM9X60, SAM9X7 and SAMA7 series have a new watchdog variant, some bitfields bof MR register shifted their position, a new register is added for timer value. 4. Add DT node to SAM9X60-Currently board It has been tested on SAM9X60-Currently board: - Start & stop - Set timeout from DT node - Reset kick in with a while(1) loop Zixun LI (7): arm: at91: wdt: Remove unused at91_wdt struct arm: at91: wdt: Rename regval in priv data to mr watchdog: at91sam9_wdt: Rename priv to wdt arm: at91: wdt: Add SAM9X60 register definition watchdog: at91sam9_wdt: Add SAM9X60 support ARM: dts: sam9x60: Add watchdog DT node.
