From: Robert Jarzmik Date: Fri, 21 Oct 2016 22:06:21 +0000 (+0200) Subject: serial: 8250: pxa: add devicetree earlyconsole X-Git-Tag: v5.15~12306^2~46 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=fea6dd14868aa8f954804cf4a629b6af3e47c484;p=platform%2Fkernel%2Flinux-starfive.git serial: 8250: pxa: add devicetree earlyconsole Transfer the device-tree pxa uart handling from 8250_of to the new 8250_pxa. As a corollary, add the early console definition into 8250_pxa. This enables to have the same uart node for the early console and the normal uart.
