2021-03-31mimxrt10xx: Fix bogus assertion.Jeff Epler
.. as noted by @d-c-d
2021-03-30mimxrt1011: UART: Add additional error checkingJeff Epler
.. and make the 'invalid pin' messages standard. Closes #4502
2021-03-26Parenthesize double-division for clarityJeff Epler
2021-03-26mimxrt10xx: Use the proper "betweenTransferDelay" (et al) valuesJeff Epler
Set the betweenTransferDelay to the SCK low-time, to avoid long pauses between bytes (transfers) while preventing the last SCK cycle in a byte from being a runt pulse. Compared to an earlier revision of this change, which just set the delays all to zero, this doesn't break using an AirLift, which was sensitive to the runt pulses (the simple loopback-wire test didn't detect the problem)
2021-03-26mimxrt10xx: Factor out "transfer_common"Jeff Epler
.. and set the "MasterPcsContinuous" flag, which removes some of the gap between bytes of a single SPI transaction
2021-03-26mimxrt10xx: busio: cap SPI baudrate at 30MHz per datasheetJeff Epler
2021-03-24mimxrt: SPI: Set the TCR value returned by MasterBaudSetRateJeff Epler
without this, the baud rate could be wrong; in my testing, it was low by a factor of 2 when requesating baudrate=1_000_000 (1MHz). When passing the baudrate in to LPSPI_MasterInit, the setting is made automatically, but LPSPI_MAster_SetBaudRate just returns it via the out-parameter tcrPrescaleValue.

This can be enforced by pre-commit, but correct it separately to make it easier to review.
