ARM: dts: Fix GPMC Ethernet timings for omap cm-t sbc-t boards for device tree
Looks like we have wrong GPMC timings we have for the cm-t and sbc-t boards. This can cause occasional strange errors with at least doing an rsync of large files or doing apt-get dist-upgrade. Let's fix the issue in two phases. First let's simplify cm-t and sbc-t to use the shared omap-gpmc-smsc911x.dtsi to avoid fixing the issue in multiple places. Then we can fix the timings in a single place with a follow-up patch. Cc: Dmitry Lifshitz <lifshitz@compulab.co.il> Signed-off-by: Tony Lindgren <tony@atomide.com>
