You're on i.MX35, right. I had to add
clk_register_clkdev(clk[ssi1_gate], NULL, "imx-ssi.0");
to arch/arm/mach-imx/clk-imx35.c to be able to access the codec.
(Obviously this is a hack, and to do it better, you'd need to change
clk_register_clkdev(clk[ssi1_div_post], "per", "imx-ssi.0");
to use ssi1_gate and fix the ssi-driver to be aware that there are two
clocks to handle.)
Best regards
Uwe
