The problem is more complicated. The cs4236+ cards have two separate PNP bios ids! The problem here is that Linux kernel allows only one id per device. The ids are CS0010* for the CS0000* device and CS0110* for the CS0100* devices. The second device has only control port range (one io range).
I have prepared the patch which I tested on my Dell Latitude CPi laptop and now it properly discovers the CS4237B codec. Stanley, please test it as well.
Takashi,
Please take a look at the patch which unifies the cs4232 and the cs4236+ driver code. It should solve all problems with the Crystal PnP BIOS chip detection. At least, it solves this at my Dell laptop.
Regards, Krzysztof
