Subject: [PATCH v4 01/14] mfd: max77686: Convert to use regmap_irq
By using the generic IRQ support in the Register map API, it
is possible to get rid max77686-irq.c and simplify the code.
Suggested-by: Krzysztof Kozlowski <k.kozlowski@...sung.com>
Signed-off-by: Javier Martinez Canillas <javier.martinez@...labora.co.uk>
Acked-by: Lee Jones <lee.jones@...aro.org>
Reviewed-by: Doug Anderson <dianders@...omium.org>

Changes since v3: None
Changes since v2:
- Cleanup regmap irqchips on i2c_driver .remove function.
Suggested by Doug Anderson.
- Remove unused MAX77686_IRQ_NR enum. Suggested by Doug Anderson.
