Cover letter [PATCH 0/4] ch341: Add support for HL340 devices
A subset of CH341 devices does not support all features, namely the prescaler is limited to a reduced precision and there is no support for sending a RS232 break condition.
These devices can usually be identified by an imprint of "340" on the turquoise-colored plug. They're also sometimes called "HL340", hence the terminology in this series and driver.
This series adds detection of these devices, adjusts the divisor/prescaler setup and implements a simulated break condition.
