Yep, of course, here's machine driver (originally created by Denis Grigoriev) 
and modified codec driver.
 
Btw, on rx1950 there're 4 gpio pins involved:
GPJ0 controls codec power
GPA1 controls amplifier power
GPG12 is jack sense pin, it's value depends whether headphone jack is inserted 
or not,
and GPD0 is connected to uda1380 reset.
