From 2b20b6164ec737bec67641564e477aa6e008748b Mon Sep 17 00:00:00 2001 From: Paul Walmsley Date: Tue, 9 Dec 2014 22:36:50 +0000 Subject: soc/tegra: pmc: restrict compilation of suspend-related support to ARM Tegra SoCs with 64-bit ARM support don't currently support deep CPU low-power states in mainline Linux. When this support is added in the future, it will probably look rather different from the existing 32-bit ARM support, since the ARM64 maintainers' strong preference is to use PSCI to implement it. So, for the time being, prevent the CPU suspend-related code and data in the Tegra PMC driver from compiling on ARM64.
