From c5ffdcaea57f6975e8790e4c1ba242d9e04227e2 Mon Sep 17 00:00:00 2001 From: =?utf8?q?C=C3=A9dric=20Le=20Goater?= Date: Tue, 11 Apr 2017 17:30:02 +0200 Subject: [PATCH] ppc/pnv: populate device tree for RTC devices MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit The code could be common to any ISA device but we are missing the IO length.
