From 294b9cb84195a9606a22a4f5d0e26b51da6c0ce1 Mon Sep 17 00:00:00 2001 From: "Derald D. Woods" Date: Tue, 12 Sep 2017 18:48:21 -0500 Subject: [PATCH 01/22] ARM: dts: omap3-evm-37xx: Add common processor module support This commit moves common OMAP3-EVM processor module device tree data to a separate include file. This will allow for 'omap3-evm.dts' to use device tree data that is unique to the OMAP3530 version of the processor module, while making use of the work already done for the 'omap3-evm-37xx.dts'.

It adds proper pinmux macros for 'omap3_pmx_core2' on OMAP3430. The Micron NAND chip is also added for the TMDSEVM3530 processor module. Signed-off-by: Derald D.
