Bug#784344: Buggy DTB causes imx53 SATA failure
Package: src:linux
Version: 3.16.7-ckt9-3~deb8u1
Severity: serious
Hi guys,
Just debugged on harris.debian.org (imx53, Debian porter box) -
there's a missing patch that's needed for the imx53 sata controller to
work. At some point, it looks like the code in drivers/ata/ahci_imx.c
has changed and arch/arm/boot/dts/imx53.dtsi needed a change to
match. It's a trivial change, just renaming the core SATA clock from
"sata_gate" to "sata". Upstream patch is in commit
025781539a3ccf867c1e0f2fc63f61cc8c7c5415.
(Adding more info for people googling for this!)
Without this patch, the SATA driver in drivers/ata/ahci_imx.c just
reports
[ 2.377276] ahci-imx 10000000.sata: can't get sata clock.
[ 2.425652] ahci-imx: probe of 10000000.sata failed with error -2
at startup. Please apply ASAP, would be lovely to get this into the
Jessie point release.
