+Subject: [PATCH] ARM: dts: orion5x: fix number of sata port for linkstation
+ ls-gl
+Origin: http://git.infradead.org/linux-mvebu.git/commit/b150e59f1d217473b3eab354a9e5e9fe907868ff
+
+Bug report from Debian [0] shows there's minor changed model of
+Linkstation LS-GL that uses the 2nd SATA port of the SoC.
+So it's necessary to enable two SATA ports, though for that specific
+model only the 2nd one is used.
