When running the codec as slave, the master should generate MCLK in the range of 256*fs, 384*fs or 512*fs, which is called asynchronous SYS_MCLK input mode. In asynchronous SYS_MCLK we cannot have the 8 to 27 MHz check because if we want to play a 8KHz sample rate track, with a MCLK of 8k * 512 = 4.096MHz the current check would return -EINVAL, which is not correct. Remove the 8 to 27MHz frequency check, since this only applies to the synchronous SYS_MCLK input case. Signed-off-by: Fabio Estevam Signed-off-by: Mark Brown --- Reading git-diff-tree failed
