[PATCH V2 00/22] watchdog: ARM watchdogs: sp805 & mpcore updates & fixes

[Viresh Kumar]

Hello,

This patchset contains fixes and updates for ARM watchdog drivers sp805 and
mpcore.

Changes since V1:
- Included patches for sp805 driver.
- Removed: wdt->clk = NULL from mpcore driver, and use IS_ERR() to check if
  clock is supported or not.
- Adapted to watchdog core for both the drivers.
- two patches for watchdog core added
- add patch to use __raw_readl{writel} instead of readl{writel}
- taken care of few more review comments.

Changes are mentioned in following patch list:
