Subject: [PATCH v5 0/2] irqchip/mchp-eic: add driver for Microchip EIC
Date: Mon, 27 Sep 2021 09:36:55 +0300	[thread overview]
Message-ID: <20210927063657.2157676-1-claudiu.beznea@microchip.com> (raw)

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 v5:
- solved the issue with dt bindings (accidentally picked file from
  v2 in previous version)

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
