From 2c88543b953581f70f05bf133a1b8f196c48ef23 Mon Sep 17 00:00:00 2001 From: Linus Walleij Date: Thu, 6 Sep 2012 09:07:27 +0100 Subject: ARM: 7515/1: integrator: check PL010 base address from resource In the PL010 UART callback a comparison against the location of the statically allocated PL010 device is done to figure out which UART is doing the callback. This does not play well with dynamic devices such as in device tree, so let's check the base address of the memory resource inside the amba_device instead.
