[PATCH v2] dt-bindings: irqchip: renesas: intc-irqpin: convert bindings to json-schema

[Yoshihiro Kaneko <ykaneko0929@gmail.com>]

Convert R-/SH-Mobile IRQPin Controller bindings documentation to json-schema.

Signed-off-by: Yoshihiro Kaneko <ykaneko0929@gmail.com>
---

v2
- correct Geert-san's E-mail address.
- delete Guennadi-san from the maintainer of this binding.
- give 'sense-bitfield-width' the uint32 type.
- describe 'control-parent' property as a boolean.

-DT bindings for the R-/SH-Mobile irqpin controller
-
-Required properties:
-
-- compatible: has to be "renesas,intc-irqpin-<soctype>", "renesas,intc-irqpin"
-  as fallback.
-  Examples with soctypes are:
-    - "renesas,intc-irqpin-r8a7740" (R-Mobile A1)
-    - "renesas,intc-irqpin-r8a7778" (R-Car M1A)
-    - "renesas,intc-irqpin-r8a7779" (R-Car H1)
-    - "renesas,intc-irqpin-sh73a0" (SH-Mobile AG5)
-
-- reg: Base address and length of each register bank used by the external
-  IRQ pins driven by the interrupt controller hardware module. The base
-  addresses, length and number of required register banks varies with soctype.
-- interrupt-controller: Identifies the node as an interrupt controller.
-- #interrupt-cells: has to be <2>: an interrupt index and flags, as defined in
-  interrupts.txt in this directory.
-- interrupts: Must contain a list of interrupt specifiers. For each interrupt
-  provided by this irqpin controller instance, there must be one entry,
-  referring to the corresponding parent interrupt.
-
-Optional properties:
-
-- any properties, listed in interrupts.txt, and any standard resource allocation
-  properties
-- sense-bitfield-width: width of a single sense bitfield in the SENSE register,
-  if different from the default 4 bits
-- control-parent: disable and enable interrupts on the parent interrupt
-  controller, needed for some broken implementations
-- clocks: Must contain a reference to the functional clock.  This property is
-  mandatory if the hardware implements a controllable functional clock for
-  the irqpin controller instance.
-- power-domains: Must contain a reference to the power domain. This property is
-  mandatory if the irqpin controller instance is part of a controllable power
-  domain.
