* bus: Document special ranges of IVARsJohn Baldwin2026-02-171-4/+6
| | | | | | | | | | | | | Some IVAR indices are special in that they have global meaning across multiple buses where as other IVARs are always private to the local bus. Try to document this a bit and add constants for the various ranges to avoid future conflicts. This is a no-op, but IVAR indices are now generally defined as enums as that makes it easier to define them in terms of ranges.

We run well on my test device (Orange Pi Zero3), however there is an uninvestigated issue with ethernet and graphics are an open question.

* aw_rtc: bump settime() delaysMitchell Horne2025-12-151-11/+12
| | | | | | | | | | | | | | | | | | | | | | | | There are delay loops, checking the BUSY status bit, before writing to the date or time registers. Each iteration contains a 1usec delay, for a maximum of 70 iterations. This is frequently not enough on the D1 platform, where the message is emitted: rtc0: could not set date, RTC busy Bump the loop delay to 10usecs each, and the maximum number of iterations to 150, for a maximum delay of 1.5msecs between each write of the register. In my testing this seems to be adequate. The loop variable is renamed for clarity/simplicity.
