Subject: [PATCH v4 4/4] clk: mvebu: armada-37xx-xtal: fill the device entry when registering the clock
Date: Tue, 8 Jan 2019 17:19:40 +0100 [thread overview]
Message-ID: <20190108161940.4814-5-miquel.raynal@bootlin.com> (raw)
In-Reply-To: <20190108161940.4814-1-miquel.raynal@bootlin.com>
So far the clk_hw_register_fixed_factor() call was not providing any
device structure. While doing so is harmless for regular use, the
missing device structure may be a problem for suspend to RAM support.
Since, device links have been added to clocks, links created during
probe will enforce the suspend/resume orders. When the device is
missing during the registration, no link can be established, hence the
order between parent and child clocks are not enforced.
Adding the device structure here will create a link between the XTAL
clock (this one) and the four TBG clocks that are derived from it.
