+DRIVER PARAMETERS
+================================================================================
+
+ Some functions for the cm8738 can be configured in Kernel Configuration
+ or modules parameters. Set these parameters to 1 to enable.
-1. Real player cannot be run (the same as es1371).
+ spdif_loop: Enable S/PDIF loop, this route S/PDIF-in to S/PDIF-out
+ directly.
+ four_ch: Enable 4 channels mode, rear-out or line-in will output
+ the same as line-out.
+ rear_out: Enable this if you have independent rear-out jacket on
+ your sound card, otherwise line-in will be used as
+ rear-out.
+ modem: You will need to set this parameter if you want to use
+ the HSP modem. You need install the pctel.o, the modem
+ driver itself.
+
+ (You will need to get the pctel driver (binary only) and the support for
+ this option from the CMI site. It is not included in the Linux kernel
+ proper as it is non-free).
