watchdog: tqmx86_wdt: Fix build error

2019-12-30T14:58:24+00:00

If TQMX86_WDT is y and WATCHDOG_CORE is m, building fails: drivers/watchdog/tqmx86_wdt.o: In function `tqmx86_wdt_probe': tqmx86_wdt.c:(.text+0x46e): undefined reference to `watchdog_init_timeout' tqmx86_wdt.c:(.text+0x4e0): undefined reference to `devm_watchdog_register_device' Select WATCHDOG_CORE to fix this.

watchdog: jz4740: Drop dependency on MACH_JZ47xx

2019-11-18T19:14:47+00:00

Depending on MACH_JZ47xx prevent us from creating a generic kernel that works on more than one MIPS board. Instead, we just depend on MIPS being set.

watchdog: jz4740: Use regmap provided by TCU driver

2019-11-18T19:14:46+00:00

Since we broke the ABI by changing the clock, the driver was also updated to use the regmap provided by the TCU driver.

watchdog: jz4740: Use WDT clock provided by TCU driver

2019-11-18T19:14:46+00:00

Instead of requesting the "ext" clock and handling the watchdog clock divider and gating in the watchdog driver, we now request and use the "wdt" clock that is supplied by the ingenic-timer "TCU" driver. The major benefit is that the watchdog's clock rate and parent can now be specified from within devicetree, instead of hardcoded in the driver. Also, this driver won't poke anymore into the TCU registers to enable/disable the clock, as this is now handled by the TCU driver. On the bad side, we break the ABI with devicetree - as we now request a different clock. In this very specific case it is still okay, as every Ingenic JZ47xx-based board out there compile the devicetree within the kernel; so it's still time to push breaking changes, in order to get a clean devicetree that won't break once it musn't.

watchdog: Add i.MX7ULP watchdog support

2019-09-17T06:59:12+00:00

The i.MX7ULP Watchdog Timer (WDOG) module is an independent timer that is available for system use. It provides a safety feature to ensure that software is executing as planned and that the CPU is not stuck in an infinite loop or executing unintended code. If the WDOG module is not serviced (refreshed) within a certain period, it resets the MCU. Add driver support for i.MX7ULP watchdog.
