Tomas Hlavacek	6915c0e487	tty: uartclk value from serial_core exposed to sysfs ... Added file /sys/devices/.../tty/ttySX/uartclk to allow reading uartclk value in struct uart_port in serial_core via sysfs. tty_register_device() has been generalized and refactored in order to add support for setting drvdata and attribute_group to the device.

Kay Sievers	fbc92a3455	tty: add 'active' sysfs attribute to tty0 and console device ... tty: add 'active' sysfs attribute to tty0 and console device Userspace can query the actual virtual console, and the configured console devices behind /dev/tt0 and /dev/console. The last entry in the list of devices is the active device, analog to the console= kernel command line option. The attribute supports poll(), which is raised when the virtual console is changed or /dev/console is reconfigured.
