From a7d84d73b9ca32871da8fc05e95ca47c04fbb110 Mon Sep 17 00:00:00 2001 From: Maxime Ripard Date: Tue, 1 Jul 2014 11:33:17 +0200 Subject: ARM: at91: PIT: Use of_have_populated_dt instead of CONFIG_OF Until now, the machines, even when CONFIG_OF was enabled, were calling at91sam926x_ioremap_pit to try to map the PIT address using the defined physical address. Obviously, with DT, it's not appropriate anymore, and some code was added to the function to deal with this case. Unfortunately, this code was conditionned on CONFIG_OF, which can be enabled, even though no DT was actually used, which would result in such a case, to this code being executed, without any reason. Moreover, the logic that was here before to bail out of the function just check in the DT to see if the PIT node is there, which is the case in all our DTSI. All this can be made much more straightforward just by using of_have_populated_dt to bail out.
