Differences between w83781d.c in 2.4 and 2.6

[com.ea at tinet.org (com.ea)]

Hello

Im continuing with my job about adding PWM clock support for the winbond family.
I noticed that the w83781d.c driver for 2.4 kernels has support for w83791d while the same driver
for 2.6 kernels doesnt (last release 2.6.17). Is anybody porting it to 2.6? 
Where can i get the code if its already done?

Thanks
