From f9c380efa792f313d3366a935fe38091d4c98ccb Mon Sep 17 00:00:00 2001 From: Jon Hunter Date: Thu, 13 Dec 2018 09:46:14 +0000 Subject: [PATCH] soc/tegra: pmc: Drop SMP dependency from CPU APIs MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit When CONFIG_SMP is disabled, the tegra clk driver now fails to build: drivers/clk/tegra/clk-tegra30.c: In function ‘tegra30_cpu_rail_off_ready’: drivers/clk/tegra/clk-tegra30.c:1151:2: error: implicit declaration of function ‘tegra_pmc_cpu_is_powered’ [-Werror=implicit-function-declaration] cpu_pwr_status = tegra_pmc_cpu_is_powered(1) || ^ Fix the above error by removing the CONFIG_SMP ifdef around the declaration around the PMC CPU APIs because although these are not needed for non-SMP configurations, there is no harm in including these for non-SMP builds either.
