Subject: [PATCH 1/4] ARM: dts: imx6q-tbs2910: add SATA PHY configuration
Date: Sun,  7 Feb 2016 19:34:30 +0100	[thread overview]
Message-ID: <1454870073-6506-1-git-send-email-smoch@web.de> (raw)

Configure SATA PHY transmit level, boost, attenuation and equalizer
parameters for long wire connections. TBS2910 contains a standard SATA
connector, so devices are typically connected with (longer) SATA cables.
And explicitly configuring these parameters avoids complaints about
"not specified" values in boot messages.
