From 271a87b4ecc498cf718738b1a5271c911eec17ff Mon Sep 17 00:00:00 2001 From: Bin Meng Date: Thu, 25 Feb 2021 17:22:50 +0800 Subject: gpio: mpc8xxx: Support controller register physical address beyond 32-bit dev_read_addr_size_index() returns fdt_addr_t which might be a 64-bit physical address. This might be true for some 85xx SoCs whose CCSBAR is mapped beyond 4 GiB.
