Subject: [PATCH 0/2] serial: add KEBA UART driver
Date: Tue, 14 Oct 2025 21:15:13 +0200 [thread overview]
Message-ID: <20251014191515.75888-1-gerhard@engleder-embedded.com> (raw)
First the serial subsystem is prepared to keep rs485 settings from the
driver if no firmware node exists. This enables drivers to configure a
default rs485 mode, which is set by the serial subsystem.
Second the driver for the KEBA UART is added. This driver supports
multiple rs485 mode and selects RS485 as default mode. This UART is
found in KEBA PLC devices. The auxiliary devices for this driver are
created by the cp500 driver.
