[PATCH 0/7] watchdog: at91sam9_wdt driver enhancement

[Zixun LI]

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
