Nevertheless, ssi1_ipg_per is disbled after loading the kernel. Digging into this a bit more, it turned out that without my patch, clk_disable_unused() recognizes ssi1_ipg_per as unused and disables it. If my patch is applied and ssi1_ipg_per is declared as parent of ssi1_ipg, clk_disable_unused() will not disable it and fsl_ssi_startup() will enable both ssi1_ipg_per and ssi1_ipg before playing sound.
