Maxime,

I believe the new compatible string should be armada-380-xor or
armada380-xor. Wildcards in compatible strings are generally not
recommended, and we don't use the a38x- prefix anywhere in the tree, as
far as I can see:

drivers/ata/ahci_mvebu.c:	{ .compatible = "marvell,armada-380-ahci", },
drivers/bus/mvebu-mbus.c:	{ .compatible = "marvell,armada380-mbus",
drivers/mmc/host/sdhci-pxav3.c:		.compatible = "marvell,armada-380-sdhci",
drivers/rtc/rtc-armada38x.c:	{ .compatible = "marvell,armada-380-rtc", },
drivers/thermal/armada_thermal.c:		.compatible = "marvell,armada380-thermal",
drivers/usb/host/xhci-plat.c:	{ .compatible = "marvell,armada-380-xhci"},
drivers/watchdog/orion_wdt.c:		.compatible = "marvell,armada-380-wdt",

Yes, we're not very consistent between armada380 and armada-380, but
we're not using a38x anywhere.

Best regards,

Thomas
