Subject: [PATCH v3 10/12] irqchip/irq-imx-gpcv2: Mark fwnode device as not initialized
Date: Mon,  6 Feb 2023 17:42:02 -0800	[thread overview]
Message-ID: <20230207014207.1678715-11-saravanak@google.com> (raw)
In-Reply-To: <20230207014207.1678715-1-saravanak@google.com>

Since this device is only partially initialized by the irqchip driver,
we need to mark the fwnode device as not initialized. This is to let
fw_devlink know that the device will be completely initialized at a
later point. That way, fw_devlink will continue to defer the probe of
the power domain consumers till the power domain driver successfully
binds to the struct device and completes the initialization of the
device.
