From: Mugunthan V N Date: Thu, 26 Nov 2015 09:19:10 +0000 (+0530) Subject: arm: dts: omap: add reg-shift to serial device tree node X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=85cf0e6299cc1909f814fe1ee1a6cf2f7e257bb7;p=project%2Fbcm63xx%2Fu-boot.git 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.
