2fbab8067a Prevent freezing USB during high frequency PulseIn.
We now track the last time the background task ran and bail on the
PulseIn if it starves the background work. In practice, this
happens after the numbers from pulsein are no longer accurate.

This also adjusts interrupt priorities so most are the lowest level
except for the tick and USB interrupts.

e580d22f4a Use the external crystal on SAMD21 again.
Also, re-enable calibration storage for CircuitPlayground Express.
Tested with a 500hz PWMOut on Metro M0 with Saleae:
 * with crystal 500hz
 * with usb 500hz +- 0.1hz
 * without either 487hz += 0.1hz

SAMD51 is skipped due to DFLL errata and the fact it defaults to a
factory calibrated 48mhz that works fine for USB.

e158702a68 atmel-samd/samd51: Use crystal for RTC
This uses the crystal to clock the RTC on boards which have a crystal.

Disable clock generator 2 which was enabled in commit
8e2080411f ("atmel-samd: Add rtc module support").
samd51 differs from samd21 when it comes to the RTC clock. samd51 doesn't
have an explicit clock peripheral so no need for a clock generator.

The same commit didn't even setup XOSC32K correctly, it missed EN1K and XTALEN.

The RTC uses the 1k clock output, so enable it on the OSCULP32K even if it works without it.

ab7ddfddd5 atmel-samd/samd51: Refactor clock setup
Refactor the convoluted asf4 clock setup into something more readable.

enable_clock_generator() has 2 changes:
- Set 'Output enabled' to match the current clock setup
- Handle divisors above 511

Add an enable_clock_generator_sync() version which makes it possible to setup
clocks without waiting for syncing. The bootup would hang without this.

I have checked these registers:

 NVMCTRL->CTRLA = 0x00000004

 Peripheral clocks (only non-zero shown):
 PCHCTRL[1]=0x00000045
 PCHCTRL[10]=0x00000041

 Generator clocks (only non-zero shown):
 GENCTRL[0] = 0x00010907
 GENCTRL[1] = 0x00010906
-GENCTRL[2] = 0x00041104
+GENCTRL[2] = 0x00200904
 GENCTRL[4] = 0x00010907
 GENCTRL[5] = 0x00180906

 DFLL clock:
 OSCCTRL->DFLLCTRLA = 0x00000082
 OSCCTRL->DFLLCTRLB = 0x00000000
 OSCCTRL->DFLLVAL = 0x00008082
 OSCCTRL->DFLLMUL = 0x00000000

 DPLL clocks:
 OSCCTRL->Dpll[0].DPLLCTRLA=0x00000002
 OSCCTRL->Dpll[0].DPLLCTRLB=0x00000000
 OSCCTRL->Dpll[0].DPLLRATIO=0x0000003b
 OSCCTRL->Dpll[1].DPLLCTRLA=0x00000080
 OSCCTRL->Dpll[1].DPLLCTRLB=0x00000020
 OSCCTRL->Dpll[1].DPLLRATIO=0x00000000

 OSC32KCTRL clock:
 OSC32KCTRL->RTCCTRL = 0x00000000
 OSC32KCTRL->XOSC32K = 0x00002082
 OSC32KCTRL->CFDCTRL = 0x00000000
 OSC32KCTRL->EVCTRL = 0x00000000
 OSC32KCTRL->OSCULP32K = 0x00002300

Only gen2 changed which is due to samd51 having more bits in the simple
division register so DIVSEL wasn't necessary, and it didn't have OE set.

mpconfigboard.h and makes the ugame10 board do that.

4adba51569 atmel-samd/samd21: Rework clock setup
Make clock setup explicit instead of using the convoluted asf4 macro setup.

enable_clock_generator():
- Add GCLK_GENCTRL_OE to stick with the current setup.
- Handle divisor larger than 31 for generator 2
- Change the source argument so it can take the GCLK_GENCTRL_SRC_XXXX_Val
  macros without casting to uint8_t.

This patch should not introduce any functional changes except keeping
GCLK_GENCTRL_OE enabled when the I2S clock is enabled.

22b7cd3d51 Fix 8 bit recordings on CPX.
The DMA trigger source was incorrect when using serializer 1 on
the SAMD21.

Playback register was incorrect for 8 bit as well. Now fixed.

681399f8db atmel-samd: RTC: Improve precision when setting datetime
The prescaler is not reset when setting the counter so we can be off by
as much as 1023/1024 seconds. Fix this by resetting the RTC module.

cfea51ec68 Re-enable PDMIn without ASF and using the helpers added with
I2SOut.

The API is almost the same except the frequency attribute has been
renamed to sample_rate so that its less likely to be confused with
frequencies within the audio itself.

Fixes #263.
