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.
