From 286ede6515bdde4550c247f0d08ed28c5dbf8db2 Mon Sep 17 00:00:00 2001 From: Mario Six Date: Wed, 20 Dec 2017 09:52:12 +0100 Subject: [PATCH] drivers: core: Add translation in live tree case The function dev_read_addr calls ofnode_get_addr_index in the live tree case, which does not apply bus translations to the address read from the device tree. This results in illegal addresses on boards that rely on bus translations being applied. Fix this situation by applying bus translations in the live tree case as well.
