Right, that's what the code does but why is this something that should
be controlled in this fashion?
This machine driver is common for TDM mode and I2S mode, user can select TDM
mode or I2S mode.
Why would the user choose one value or the other, and why would this
choice be something that only changes at module load time? If this is
user controllable I'd really expect it to be runtime controllable.
You're not explaining why this is a module parameter.
Different vendors/OEM's use the same hardware as one need I2S mode and
other need TDM mode, using common driver to support I2S and TDM mode
with this parameter.
static int tdm_mode = 0;
module_param_named(tdm_mode, tdm_mode, int, 0444);
And this can be runtime controllable by setting permissions as 0644, we
will change and send next version patch.
