[resend from correct email this time.]

All,

On yesterday's call we brainstormed about what topics we want to talk about on this call going forward. We also said we will continue with the bi-weekly cadence for a few meetings and then reassess if we should go monthly instead.

Attending: * Loic * Mark * Etienne * Arnaud * Rob * Ilias * Bill * Joakim

Here is the topic list in no specific order:

* New DT format * Overlays in kernel * overlays for PCI or USB devices (in an ACPI based system) * DT for other OSes * Zephyr DT schema conformance * ABI stability & testing * source code sync * U-boot DT handling

We discussed the ABI issue a bit: Rob: SystemReady IR 2.0 requires schema conformance * There are still open questions + what version of schema + how many warnings allowed * discussion mostly inside ARM * 2.0 will come out this fall Bill: But you can have two DTBs that full conform to schema and are still ABI breaking * Example: ST moving from direct kernel Power/clk control to SCMI * Current recommendation from this group is make new kernels work both ways until all firmware will have been updated * The switch over time could be a couple of years for a GP platform. Loic: It is very difficult to make a kernel that works both ways * Not all customers see the benefit, (mostly security) * Some want to keep doing things the old way Bill: Even if everyone agrees to switch the transition period is hard to handle in anything except a vertical OS.

We discussed recent status of U-boot DT handling a bit but need a more structured discussion / investigation.
