2017-09-04 | watchdog: wdt_aspeed: Add support for the reset width register | Andrew Jeffery | |
The reset width register controls how the pulse on the SoC's WDTRST{1,2} pins behaves. A pulse is emitted if the external reset bit is set in WDT_CTRL. On the AST2500 WDT_RESET_WIDTH can consume magic bit patterns to configure push-pull/open-drain and active-high/active-low behaviours and thus needs some special handling in the write path. As some of the capabilities depend on the SoC version a silicon-rev property is introduced, which is used to guard version-specific behaviour.

2017-02-07 | wdt: Add Aspeed watchdog device model | Cédric Le Goater | |
The Aspeed SoC includes a set of watchdog timers using 32-bit decrement counters, which can be based either on the APB clock or a 1 MHz clock. The watchdog timer is designed to prevent system deadlock and, in general, it should be restarted before timeout. When a timeout occurs, different types of signals can be generated, ARM reset, SOC reset, System reset, CPU Interrupt, external signal or boot from alternate block. The current model only performs the system reset function as this is used by U-Boot and Linux.
