Subject: [PATCH v1 2/2] spi: Populate fwnode in of_register_spi_device()
Date: Wed, 4 Nov 2020 12:54:31 -0800 [thread overview]
Message-ID: <20201104205431.3795207-2-saravanak@google.com> (raw)
In-Reply-To: <20201104205431.3795207-1-saravanak@google.com>
From: Daniel Mentz <danielmentz@google.com>
This allows the fw_devlink feature to work for spi devices
too. This avoids unnecessary probe deferrals related to spi devices and
improves suspend/resume ordering for spi devices when fw_devlink=on.
