Hi,
This series adds support for Microchip External Interrupt Controller
present on SAMA7G5. The controller supports for 2 external interrupt
lines and is connected to GIC as follows:
pinX +------+ EXT_IRQ0 +------+ int 153 (for pinX) +------+
------>| |--------->| |------------------->| |
pinY | PIO | EXT_IRQ1 | EIC | int 154 (for pinY) | GIC |
------>| |--------->| |------------------->| |
+------+ +------+ +------+
where PIO is the pin controller.
Thank you,
Claudiu Beznea
Changes in v4:
- use irq_domain_translate_twocell() instead of mchp_eic_domain_translate()
from v2
- use IRQCHIP_PLATFORM_DRIVER_BEGIN(), IRQCHIP_MATCH(),
IRQCHIP_PLATFORM_DRIVER_END() instead of builtin_platform_driver()
- register suspend/resume functins via syscore_ops; along with this
driver private data structure (of type struct mchp_eic has been declared
as static: struct mchp_eic *eic;)
- collected tags
Changes in v3:
- fix compilation warning on bindings
Changes in v2:
- s/mchp/microchip in bindings
- get rid of glitch filter settings
- use s/eic@/interrupt-controller@ in bindings
- removed '' around interrupts in bindings as proposed by Rob
- removed glitch filter settings
- switched to hierarchical irqchip driver
- addressed review comments
- use builtin_platform_driver instead of module_platform_driver
