Subject: memory: omap-gpmc: Make 'bank-width' property optional
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=c18a7ac3398d0cef29749f9568666db8321aa4c9;p=openwrt%2Fstaging%2Fblogic.git

memory: omap-gpmc: Make 'bank-width' property optional

Error out only if both 'bank-width' and 'gpmc,device-width' are missing.
As 'bank-width' is mostly used for NOR devices and all other devices must
use 'gpmc,device-width' update the error message accordingly.
