We add basic chip support for Mediatek MT8189 on evaluation board.
In this series, we also add dt-bindings document definition for MT8189.
This series is based on tag: next-20250714
Changs in v4:
- Correct cpu-idle-states
- Change the "reg" property name of the "memory" node in the
device tree source (DTS) to lowercase.
Changs in v3:
- Move ulposc and ulposc3 before cpu nodes.
- Refactor cpu-map to a single cluster0.
- Change cpu nodes name from medium core to big core.
- Move psci before timer nodes.
Changs in v2:
- Fix warning issues for make CHECK_DTBS=y
- Add mediatek,uart.yaml document

All of that is in its early stages and it doesn't make a lot of sense to start this devicetree with just that - especially because, well, your target is to upstream way more than that, right? So just make it right - add the topckgen and infracfg_ao clocks and then just add in all of the UART controllers with their CLK_INFRA_AO_UART(N) clock for an initial devicetree. Count that if you add the topckgen and infra_ao clocks, you'd be able to even add the i2c, spi, mmc and others - but I will accept an initial devicetree with just all of the UART controllers and without the extra busses for a start, there's no problem with that. You can add those later if you wish. Cheers, Angelo > + clock-names = "baud", "bus"; > + status = "disabled"; > + }; > + }; > +}; ^ permalink raw reply [flat|nested] 7+ messages in thread

This approach enables other drivers to be upstreamed together and includes the Makefile to allow code compilation. We plan to submit the driver source code , DTS, and dt-bindings together in the upcoming patch series. > > > + clock-names = "baud", "bus"; > > + status = "disabled"; > > + }; > > + }; > > +}; > ^ permalink raw reply [flat|nested] 7+ messages in thread
