+What: /sys/class/tty/console/active
+Date: Nov 2010
+Contact: Kay Sievers <kay.sievers@vrfy.org>
+Description:
+ Shows the list of currently configured
+ console devices, like 'tty1 ttyS0'.
+ The last entry in the file is the active
+ device connected to /dev/console.
+ The file supports poll() to detect virtual
+ console switches.

+What: /sys/class/tty/ttyS0/uartclk
+Date: Sep 2012
+Contact: Tomas Hlavacek <tmshlvck@gmail.com>
+Description:
+ Shows the current uartclk value associated with the
+ UART port in serial_core, that is bound to TTY like ttyS0.
+ uartclk = 16 * baud_base
+
+ These sysfs values expose the TIOCGSERIAL interface via
+ sysfs rather than via ioctls.

+What: /sys/class/tty/ttyS0/rx_trig_bytes
+Date: May 2014
+Contact: Yoshihiro YUNOMAE <yoshihiro.yunomae.ez@hitachi.com>
+Description:
+ Shows current RX interrupt trigger bytes or sets the
+ user specified value to change it for the FIFO buffer.
+ Users can show or set this value regardless of opening the
+ serial device file or not.
+
+ The RX trigger can be set one of four kinds of values for UART
+ serials. When users input a meaning less value to this I/F,
+ the RX trigger is changed to the nearest lower value for the
+ device specification. For example, when user sets 7bytes on
+ 16550A, which has 1/4/8/14 bytes trigger, the RX trigger is
+ automatically changed to 4 bytes.
