[PATCH v2 0/2] tty: serial: Add mediatek UART driver

[Matthias Brugger]

This patch set adds support for the UART found in Mediatek SoCs.
The chip is a changed version of a 8250 controller.
Especially it introduces a new register called highspeed. The value
in this register has to be set depending on the baudrate. The value
in the register influences the way the divisor has to be calculated.

The patch series is build against v3.16-rc1 and tested on mt6589. Should
work as well on mt6577 and mt6582.

Thanks,
Matthias

Changes for v2:
- drop 8250_core capability extension for the chip
- encapsulate set_termios in the driver method
