writing an alsa driver

[Michele Curti <michele.curti@gmail.com>]

Hi all,
I'm going to *try* to "write" a driver for the sound card on my new laptop,
an asus x205ta.

To be fair I have almost no experience but I'm hoping that all the code is
already present and it only needs some adaptations.

The cpu is a intel bay trail z3735f, the sound card is a realtek rt5648 that
has the same product Id of the rt5645 (0x6308).

I see in kernel sources:
 - the codec driver
	sound/soc/codecs/rt5645.c
 - a baytrail board that uses the rt5640
	sound/soc/intel/boards/byt-rt5640.c
 - a braswell board that uses the rt5645
	sound/soc/intel/boards/cht_bsw_rt5645.c

What do you think?  Is it feasible, given a good amount of free-time? :p

Thanks,
Michele
