From 23c74bf5fe592dff5f6b07c62fa3f909d917f308 Mon Sep 17 00:00:00 2001 From: Tony Lindgren Date: Fri, 16 Oct 2015 12:32:33 -0700 Subject: [PATCH] ARM: dts: Add basic support for isee igepv5 With omap5-board-common.dtsi, we can now easily add support for various omap5 board variants. Let's add minimal support for isee igepv5. So far I've tested that basic things work, such as serial, USB Ethernet, HDMI and WLAN. Note that like omap5-uevm, these boards seem to need to reserve 16MB for a trap section as in commit 03178c66d289 ("ARM: dts: omap5-evm: Update available memory to 2032 MB") and also noted in a u-boot commit at http://marc.info/?l=u-boot&m=134376852603255 and also at http://patchwork.ozlabs.org/patch/159881/. Not sure why this is not needed for omap5-cm-t54.dts, maybe because of different u-boot configuration.
