dt-bindings: Drop more redundant 'maxItems/minItems' in if/then schemas

2022-06-07T16:08:02Z

Another round from new cases in 5.19-rc of removing redundant minItems/maxItems when 'items' list is specified. This time it is in if/then schemas as the meta-schema was failing to check this case. If a property has an 'items' list, then a 'minItems' or 'maxItems' with the same size as the list is redundant and can be dropped. Note that is DT schema specific behavior and not standard json-schema behavior. The tooling will fixup the final schema adding any unspecified minItems/maxItems.

dt-bindings: watchdog: renesas,wdt: R-Car V3U is R-Car Gen4

2022-05-21T08:09:31Z

Despite the name, R-Car V3U is the first member of the R-Car Gen4 family. Hence move its compatible value to the R-Car Gen4 section.

dt-bindings: watchdog: da9062: add watchdog timeout mode

2022-05-21T08:09:29Z

Document the watchdog timeout mode property. If this property is used the user can select what happens on watchdog timeout. Set this property to 1 to enable SHUTDOWN (the device resets), set it to 0 and the device will go to POWERDOWN on watchdog timeout. If this property is not set, don't touch the WATCHDOG_SD bit and leave the configuration to OTP. This way backward compatibility is not broken.

dt-bindings: watchdog: sunxi: clarify clock support

2022-05-08T08:34:06Z

Most Allwinner SoCs have just one input clock to drive the watchdog peripheral. So far this is the 24 MHz "HOSC" oscillator, divided down internally to 32 KHz. The F1C100 series watchdog however uses the unchanged 32 KHz "LOSC" as its only clock input, which has the same effect, but let's the binding description mismatch. Change the binding description to name the clocks more loosely, so both the LOSC and divided HOSC match the description. As the fixed clock names now make less sense, drop them from SoCs supporting just one clock input, they were not used by any DT anyway. For the newer SoCs, supporting a choice of two input clocks, we keep both the description and clock-names requirement.
