Hi!

Now that you have done this, you should clean up the unused
bitmasks/offsets etc in
tsens-8960.c file as well as a separate patch. I only see the
need to maintain SLP_CLK_ENA_8660 and SLP_CLK_ENA. Everything else can
be removed and the s/w can use priv->rf[_field_] for access.
Otherwise for this patch
