* USB: serial: upd78f0730: make constants staticMaksim Salau2017-06-011-3/+3
| | | | | | | | | Some local constants don't change from call to call and are good candidates to become static. This will prevent copying of these constants to stack during runtime. Signed-off-by: Maksim Salau <maksim.salau@gmail.com> Signed-off-by: Johan Hovold <johan@kernel.org>

* USB: serial: upd78f0730: add ID for EVAL-ADXL362ZMaksim Salau2017-02-131-2/+3
| | | | | | | | | | The adaptor on Analog Devices EVAL-ADXL362Z development board is used to flash and debug firmware of on-board Renesas RL78/G13 MCU. Also added support of the 153600 baud rate, since the stock firmware uses it. Signed-off-by: Maksim Salau <maksim.salau@gmail.com> Signed-off-by: Johan Hovold <johan@kernel.org>
* USB: serial: add uPD78F0730 USB to Serial Adaptor DriverMaksim Salau2017-01-261-0/+440
The adaptor can be found on development boards for 78k, RL78 and V850 microcontrollers produced by Renesas Electronics Corporation. This is not a full-featured USB to serial converter, however it allows basic communication and simple control which is enough for programming of on-board flash and debugging through a debug monitor. uPD78F0730 is a USB-enabled microcontroller with USB-to-UART conversion implemented in firmware. This chip is also present in some debugging adaptors which use it for USB-to-SPI conversion as well. The present driver doesn't cover SPI, only USB-to-UART conversion is supported.
