From 85cf0e6299cc1909f814fe1ee1a6cf2f7e257bb7 Mon Sep 17 00:00:00 2001 From: Mugunthan V N Date: Thu, 26 Nov 2015 14:49:10 +0530 Subject: [PATCH] arm: dts: omap: add reg-shift to serial device tree node With the commit 'c7b9686d5d48 ("ns16550: unify serial_omap")' all TI platforms are broken with DM/DT boot as ns16550 driver expects reg-shift from DT which is not populated for TI platforms. Earlier it worked as it was hard coded to 2 in serial-omap driver. So adding the reg-shift to serial nodes for dra7, am4372 and am33xx dtsi files. Tested this patch on am437x-sk-evm, am437x-gp-evm, am335x-boneblack, dra74x-evm and dra72x-evm.
