rtc: pcf85063: add support for fixed clock

2021-10-15T19:08:45+00:00

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").

dt-bindings: Remove "status" from schema examples

2021-07-27T14:03:12+00:00

There's no reason to have "status" properties in examples. "okay" is the
default, and "disabled" turns off some schema checks ('required'
specifically).

Enabling qca,ar71xx causes a warning, so let's fix the node names:

dt-bindings: More dropping redundant minItems/maxItems

2021-07-15T14:45:27+00:00

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.
