The DHT11/DHT21/DHT22 cannot be sampled more than once a second. Previously,
a global cache was added to the SAUL adaption of the dht driver to answer with
stored values for one second after the last read. This however had two
disadvantages:
- The global cache was shared for all DHTXX devices connected. As a result
incorrect values were delivered when reading out multiple sensors over SAUL
with less than 1 second delay in between
- A user of the low level API will had to implement the same caching strategy,
resulting in code duplication
By moving the hold logic to the driver, both limitations can be overcome.
Previously the DHT11/DHT21/DHT22 driver ended up in an infinite loop locking up
RIOT when a communication error occurred. This commit adds a simple timeout to
the communication in order to prevent these lock ups.
stm32eth: Move to stm32_common periph
cpu/stm32_periph_eth: Rebase to current master branch
- Update DMA to use new vendor headers
- Update send to use iolist. It looks like the packet headers are now transfered as seperate iolist entries which results in the eth periph sending each header as own packet. To fix this a rather ugly workaround is used where the whole iolist content is first copied to a static buffer. This will be fixed soon in another commit
- If MAC is set to zero use luid to generate one
- Small code style fixes

`tsrb` changed to that type, so there is no reason for us, to keep the
internally used buffer as a `char` (especially since the rest of the
driver already uses `uint8_t`)
The MRF24J40MC/MD/ME modules contain an external power amplifier &
low noise amplifier that has to be enabled manually by setting three bits
in the TESTMODE register.
On MRF24J40MC the power amplifier is powered by a separate voltage regualtor
that has to be enabled by setting GPIO3 to HIGH.
During Sleep and CCA the PA should be disabled.

This driver is compliant with the candev interface. It has been tested
with STM32F0 and STM32F2 and STM32F413 ONLY at this time but should be
compliant with other STM32Fx devices
This commit adds usbdev, a common API to interface USB peripheral
devices. The API is split into two parts, one for the USB device itself
and one for the USB endpoint.
