Since devices have to have CDC and MSC to be "CircuitPython", this is not a facility that is going to be used by any in-tree drivers. supervisor.mk: Compute USB_DEVICES; remove from boards and ports 2020-06-23T17:59:01+00:00 Jeff Epler jepler@unpythonic.net 2020-06-16T00:12:04+00:00 urn:sha1:f232aef7865c4e094f060f9766418f60fb9f86ea Since Actions passed on the previous commit, where this computed value was checked against the specified value (if any), this is no net change, except that we no longer need to specify it for particular boards or ports. supervisor.mk: Compute what USB_DEVICES should be, and check it against what it is 2020-06-16T00:14:57+00:00 Jeff Epler jepler@unpythonic.net 2020-06-15T19:52:35+00:00 urn:sha1:8bbd539031fbcc9366c51f1d06c77a72d240d812 Initial ESP32S2 port. 2020-05-15T22:36:16+00:00 Scott Shawcroft scott@tannewt.org 2020-04-17T23:23:28+00:00 urn:sha1:6aaab005c5f3a781fec229640c74bf44a601fc97 Basic blinky works but doesn't check pins.

This mostly would have broken gamepad tick support on non-samd ports. The "ms32" and "ms64" variants of the tick functions are introduced because there is no 64-bit atomic read. Disabling interrupts avoids a low probability bug where milliseconds could be off by ~49.5 days once every ~49.5 days (2^32 ms). Avoiding disabling interrupts when only the low 32 bits are needed is a minor optimization. Testing performed: on metro m4 express, USB still works and time.monotonic_ns() still counts up
