[PATCH 1/2] Revert "USB: serial: ch341: add new Product ID for CH341A"

From: Frank Zago
Date: Mon Apr 19 2021 - 22:25:34 EST


From: frank zago <frank@xxxxxxxx>

The 0x5512 USB PID is for the I2C/GPIO/SPI interfaces. UART is still
present but only the TX and RX pins are available; DTS, DTR, ... are
used for other things. Remove the PID, and let a I2C driver bind to
it.

Existing CH341 boards usually have physical jumpers to switch between
the 3 modes.

This reverts commit 46ee4abb10a07bd8f8ce910ee6b4ae6a947d7f63.
