From 70d22b78d3235303555c921246e3c1ec37b0a29c Mon Sep 17 00:00:00 2001 From: Bjorn Andersson Date: Thu, 23 May 2019 08:01:53 -0700 Subject: [PATCH] soc: qcom: apr: Don't use reg for domain id The reg property represents the address and size on the bus that a device lives, but for APR the parent is a rpmsg bus, which does not have numerical addresses. Simply defining #address/#size-cells to 1 and 0, respectively, to silence the compiler is not an appropriate solution. Replace the use of "reg" with an APR specific property.
