Which file calls the tegra_audio_clk_init function in clk-tegra-audio.c?
I saw that although Clk-tegra114.c,Clk-tegra124.c,Clk-tegra210.c,Clk-tegra30.c called tegra_audio_clk_init, they are not compiled into the kernel.
I assume that you are using rel28.x. For TX2 this file is not used because all the clock configuration is handled by the BPMP co-processor and the BPMP firmware has all the clock information for the device. For TX1 this file is used and the function is called by clk-tegra210.c.
