Subject[PATCH v6 0/3] Deprecate interrupt-map for realtek-rtl IRQ driver
Date
The original implementation for this interrupt controller/router used
an interrupt-map parser to determine which parent interrupts were
present. However, this controller is not transparent, so a list of
parent interrupts seems more appropriate, while also getting rid of the
assumed routing to parent interrupts.

Changes since v5:
Link: https://lore.kernel.org/all/cover.1644864700.git.sander@svanheule.net/

- Allow interrupt-map for new compatibles, but mark as deprecated
- Change back to single-cell interrupt specifiers
- Drop patch adding a domain for every output line

Changes since v4:
Link: https://lore.kernel.org/all/cover.1644165421.git.sander@svanheule.net/

- Add Rob's Reviewed-by
- Use irq_domain_add_linear instead of irq_domain_add_simple
- Drop 'inline' specifiers from static functions
- Drop WARN in intc_select() to only warn once for old bindings

Changes since v3:
Link: https://lore.kernel.org/all/cover.1641739718.git.sander@svanheule.net/

- Patches with fixes were merged, so these are no longer included.
- Update the devicetree changes to more clearly indicate the controller
is not transparent.

Changes since v2 (RFC):
Link: https://lore.kernel.org/all/cover.1640548009.git.sander@svanheule.net/

- Define new, two-part compatibles for devicetree bindings. The existing format
is kept for the old one-part compatible, but deprecated. New compatibles will
require a different way of specifying parent interrupts and interrupt routing.
- Add change to handle all pending SoC interrupts in one go.

Changes since v1 (RFC):
Link: https://lore.kernel.org/all/cover.1640261161.git.sander@svanheule.net/

- Split some of the changes to limit the patch scope to one issue.
- Dropped some small (spurious or unneeded) changes
- Instead of dropping/replacing interrupt-map, the last patches now provide an
implementation that amends the current situtation.

Sander Vanheule (3):
irqchip/realtek-rtl: use irq_domain_add_linear
dt-bindings: interrupt-controller: realtek,rtl-intc: require parents
irqchip/realtek-rtl: use parent interrupts
