Handling of the watchdog requires poking PMU, thus the watchdog device node must have reference to the PMU node. Removing it from DTS makes the hardware representation incomplete, beside mentioned driver issue. Best regards, Krzysztof

The watchdog driver no longer requires a phandle to obtain a regmap to the PMU registers. So mark this as deprecated. Signed-off-by: Peter Griffin <peter.griffin@linaro.org> --- .../devicetree/bindings/watchdog/samsung-wdt.yaml | 15 +-------------- 1 file changed, 1 insertion(+), 14 deletions(-)
