[SOLVED] Choosing RTC drivers

While configuring the kernel (package https://aur.archlinux.org/packages/linux-ck/), I have found myself in trouble when I was asked for the RTC drivers

Device drivers  ->  Real Time Clock
Generic RTC class support. If you say yes here, you will be allowed to plug one or more RTCs to your system. You will probably want to enable one or more of the interfaces below.

Now, I'm not sure. My system is an HP 6735s (laptop); I've tried searching many times with many different patterns but had no luck. I've also tried lshw and lspci, the rtctest program provided here, and even looking through /sys, but... nothing!

So, here goes my question: how can I find which model of RTC I have? (what drivers I have to add to the kernel)

I know this may be an stupid question as I can be misunderstanding basic concepts. It may also be stupid because the kernel works like a charm having lots of drivers enabled. But I'd like to know more about this... and, also, disable things I don't need (as I'm doing with anything else in the kernel).

PC-style CMOS, i.e. CONFIG_RTC_DRV_CMOS
