cpu/saml1x: update periph status implementation in board doc.txt

[Einhornhool]

Contribution description

Updated the implementation status of the boards saml10-xpro and saml11-xpro.
Before only support of low-level drivers GPIO, UART and Timer was documented.
Testing showed that I2C, SPI, RTT, RTC, RNG and ADC also work on both boards.

Testing procedure

I ran the following tests:
periph_i2c
periph_spi
periph_rtt
periph_rtc
periph_adc
rng

I just ran tests/periph_adc on a saml11-xpro which works somehow but I think something might be messed up in the peripheral driver implementation. In main.c we sample with 10 bit but the test prints values between ~ 96 ... 65520 for ~0...3.3V which shouldn't be possible at 10 bit right? @dylad any ideas?

I'll take a closer look at it next week.

@dylad any ideas?

I have one. I'll submit a PR soon so you can fully test it.
Thanks for spotting this @PeterKietzmann !

[dylad]

@Einhornhool regarding this PR, do you want to wait for #11647 to be merge first so we can merge this one or you can remove hwrng support from the list and we can merge it right now.

[Einhornhool]

@dylad
I just took a look at that pr. Isn't it already merged?
I can still remove rng support, if you're not sure it works.

Thank you for working on this =)

[PeterKietzmann]

Yeah it's been merged in the meantime, no need to remove RNG support - it's been tested. However, there are open issues with the ADC implementation. @dylad any news on that?

[dylad]

@PeterKietzmann #11972 should fixes your issue, I have limited access to my hardware because I'm moving so I cannot fully test it right now.

[PeterKietzmann]

ADC's are fine with #11972. @Einhornhool please adopt @benpicco's comment. We are ready to merge afterwards.

[Einhornhool]

@PeterKietzmann Thanks, will do. Guess I made a mistake there.

[benpicco]

I'd say you can squash right away.

[Einhornhool]

@benpicco done
