From 3f5b45ca4f95a65a5164b3219c7fec64eff08638 Mon Sep 17 00:00:00 2001 From: Greg Kurz Date: Fri, 13 Dec 2019 13:00:18 +0100 Subject: [PATCH] ppc/pnv: Pass XSCOM base address and address size to pnv_dt_xscom() MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Since pnv_dt_xscom() is called from chip specific dt_populate() hooks, it shouldn't have to guess the chip type in order to populate the "reg" property. Just pass the base address and address size as arguments.
