Subject: [PATCH 00/12] Bring suspend to RAM support to PCIe Aardvark driver
Date: Fri, 23 Nov 2018 15:18:19 +0100 [thread overview]
Message-ID: <20181123141831.8214-1-miquel.raynal@bootlin.com> (raw)
Hello,
As part of an effort to bring suspend to RAM support to Armada 3700
SoCs (main target: ESPRESSObin), this series handles the work around
the PCIe IP.
First, more configuration is done in the 'setup' helper as inspired
from the U-Boot driver. This is needed to entirely initialize the IP
during future resume operation (patch 1).
Then, reset GPIO, PHY and clock support are introduced (patch 2-4). As
current device trees do not provide the corresponding properties, not
finding one of these properties is not an error and just produces a
warning. However, if the property is present, an error during PHY
initialization will fail the probe of the driver.
Note: To be sure the clock will be resumed before this driver, a first
series adding links between clocks and consumers has been submitted,
see [1].
Patch 5 adds suspend/resume hooks, re-using all the above.
Finally, bindings and device trees are updated to reflect the hardware
(patch 6-12). While the clock depends on the SoC, the reset GPIO and
the PHY depends on the board so the clock is added in the
armada-37xx.dtsi file while the two other properties are added in
armada-3720-espressobin.dts.
