The sclk_ioclk_i2s1_bclk clock is not currently handled by any driver and disabling this clock by the clk core prevents proper operation of the I2S1 block. CLK_IGNORE_UNUSED flag is added as a temporary fix.

If any device driver handles the sclk_ioclk_i2s1_bclk on later, CLK_IGNORE_UNUSED will be ignored. Looks good to me. Reviewed-by: Chanwoo Choi <cw00.choi@samsung.com> -- Best Regards, Chanwoo Choi Samsung Electronics
