> Changes in v4:
>  - Refactored IRQ domain handling due to deprecation of function
>    irq_domain_add_tree() to use the new irq_domain_create_tree()
>  - Added .irq_eoi() callback for rcs_irq as that better reflects
>    the actual functionality of this interrupt controller (as its
>    SLV_x_y_EINT registers are really signaling "EOI", not "ACK")
>  - Fixed to use generic_handle_domain_irq_safe() to avoid races
>  - Tested again on MT8196 Chromebook
> 
> Changes in v3:
>  - Added Fixes tag to commit 3, collected R-b tag from wenst
> 
> Changes in v2:
>  - Fixed indentation error in dt-bindings
> 
> This series adds basic support for multi-bus (multi-master) SPMI
> controllers, as found in the MediaTek MT8196 Chromebook SoC and
> the MediaTek MT6991 Dimensity 9400 Smartphone SoC, including RCS
> interrupt handling and per-bus registration.
