| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another round 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | These new RTC variants all have a single alarm, like the R40 variant. For the new SoCs, start requiring a complete list of input clocks. The H616 has three required clocks. The R329 also has three required clocks (but one is different), plus an optional crystal oscillator input. The D1 RTC is identical to the one in the R329. And since these new SoCs will have a well-defined output clock order as well, they do not need the clock-output-names property.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TQ-Systems' TQMa8Mx module (SoM) uses a pcf85063 as RTC. The default output is 32768Hz. This is to provide the i.MX8M CKIL clock. Once the RTC driver is probed, the clock is disabled and all i.MX8M functionality depending on the 32 KHz clock will halt. In our case the whole system halts and a power cycle is required. Referencing the pcf85063 directly results in a deadlock. The kernel will see, that i.MX8M system clock needs the RTC clock and do probe deferral. But the i.MX8M I2C module never becomes usable without the i.MX8M CKIL clock and thus the RTC's clock will not be probed. So from the kernel's perspective this is a chicken-and-egg problem. Technically everything is fine by not touching anything, since the RTC clock correctly enables the clock on reset (i.e. on battery backup power loss). A workaround for this issue is describing the square wave pin as fixed-clock, which is registered early and basically how this pin is used on the i.MX8M. This addresses the exact same issue as in commit f765e349c3e1 ("rtc: m41t80: add support for fixed clock").

|/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Another round of removing redundant minItems/maxItems from new schema in the recent merge window. 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. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.

| * rtc: m41t80: add support for fixed clockSebastian Reichel2021-05-251-0/+9
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Congatec's QMX6 system on module (SoM) uses a m41t62 as RTC. The modules SQW clock output defaults to 32768 Hz. This behaviour is used to provide the i.MX6 CKIL clock. Once the RTC driver is probed, the clock is disabled and all i.MX6 functionality depending on the 32 KHz clock has undefined behaviour. For example when using the hardware watchdog the system will likely do arbitrary reboots. Referencing the m41t62 directly results in a deadlock. The kernel will see, that i.MX6 system clock needs the RTC clock and do probe deferral. But the i.MX6 I2C module never becomes usable without the i.MX6 CKIL clock and thus the RTC's clock will not be probed. So from the kernel's perspective this is a chicken-and-egg problem. Technically everything is fine by not touching anything, since the RTC clock correctly enables the clock on reset (i.e. on battery backup power loss) and also the bootloader enables it in case an something (e.g. an unpatched kernel) disabled this incorrectly. A workaround for this issue is describing the square wave pin as fixed-clock, which is registered early and basically how this pin is used on the i.MX6.

* | dt-bindings: Drop redundant minItems/maxItemsRob Herring2021-06-212-2/+0

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. This condition is partially checked with the meta-schema already, but only if both 'minItems' and 'maxItems' are equal to the 'items' length. An improved meta-schema is pending.
