490ac7af8b watchdog: at91sam9_wdt: Convert to use the watchdog framework
According to Documentation/watchdog/convert_drivers_to_kernel_api.txt,
remove the file_operations struct, miscdevice, and obsolete includes

Since the at91sam watchdog inherent characteristics, add the watchdog
operations: at91wdt_start, at91wdt_stop and at91wdt_ping.

6c41e47486 watchdog: at91sam9: at91_wdt_dt_ids cannot be __init
The device IDs are referenced by the driver and potentially
used beyond the init time, as kbuild correctly warns
about. Remove the __initconst annotation.

Without this patch, building at91_dt_defconfig results in:

WARNING: drivers/watchdog/built-in.o(.data+0x28): Section mismatch in reference from the variable at91wdt_driver to the (unknown reference) .init.rodata:(unknown)
The variable at91wdt_driver references
the (unknown reference) __initconst (unknown)

2fc5d52b21 watchdog: remove empty pm-functions
While checking what watchdog drivers usually do in suspend/resume to
spot common behaviour for the watchdog framework, I found these drivers
which do nothing but add some cruft. Remove it, it is superfluous. New
approaches should probably be done with pm_ops anyway.

2af29b7861 [ARM] 5390/1: AT91: Watchdog fixes
The recently merged AT91SAM9 watchdog driver uses the
AT91SAM9X_WATCHDOG config variable, whereas the original version of
the driver (and the platform support code) used AT91SAM9_WATCHDOG.
This causes the watchdog platform_device to never be registered, and
therefore the driver not to be initialized.

This patch:
- updates the platform support code to use AT91SAM9X_WATCHDOG.
- includes <linux/io.h> to fix compile error (same fix as was applied
to at91rm9200_wdt.c)
- fixes comment regarding watchdog clock-rates in at91rm9200.

c1dfda399a SAM9 watchdog: update for moved headers
The architecture header files were recently moved from
include/asm-arm/mach-at91/ to arch/arm/mach-at91/include/mach/.  The SAM9
watchdog driver still includes a header from the old location.
