Subject: [PATCH v4 09/14] irqchip: Provide platform_device to of_irq_init_cb_t
Date: Fri,  8 Oct 2021 19:20:18 -0700	[thread overview]
Message-ID: <20211009022023.3796472-10-f.fainelli@gmail.com> (raw)
In-Reply-To: <20211009022023.3796472-1-f.fainelli@gmail.com>

Provide the platform device mapping to the interrupt controller node to
the of_irq_init_cb_t callback such that drivers can make use of it.
