Hello,
This series adds a new driver to support Armada 3700 COMPHY IP.
The series has been tested on an ESPRESSObin with SATA, PCIe
and USB3 host. For this purpose, patch 1 enumerates the SATA PHY
mode. The SGMII PHY mode that is supported by the IP has been written
(uses SMC calls anyway) but could not be tested on this platform.
Three series will follow to add PHY support (or at least a PHY nodes
in the A3700/ESPRESSObin device trees) to the MVEBU AHCI driver, the
Aardvark PCI controller driver and the MVEBU xHCI driver. All this is
needed in order to achieve suspend to RAM on this platform.
Thanks,
Miquèl
Changes since v4:
=================
* Fixed error in the driver probe where PHY_INTERFACE_MODE_NA was
assigned to lane->mode instead of lane->submode.
* Compile-in the driver by default (depends on ARCH_MVEBU).
* Add dependency on HAVE_ARM_SMCC in Kconfig.
Changes since v3:
=================
* Added Rob's Reviewed-by tag on bindings.
* Rebased on top of phy -next as of the 12th of December, 2018.
* Adapted the driver to support SGMII/1000BASEX and
HS_SGMII/2500BASEX.
Changes since v2:
=================
* Remove redundant check on lane->port/args->arg[0] at the end of the
->xlate() callback. Do it on both armada-cp110 and armada-a3700
COMPHY drivers.
* Put my SoB as author of the patch first when a patch is co-developed.
Changes since v1:
=================
* Fix wrong check in ->xlate().
* Apply the same fix to the cp110 comphy driver from which the a3700
driver is based.
* Added credit to Gregorz Jaszczyk for his work.
* Added Suggested-by tag to the patch adding the COMPHY DT node.
