Subject: Re: [PATCH v4 0/2] tty: serial: Add mediatek UART driver

2014-08-12 16:12 GMT+02:00 Matthias Brugger <matthias.bgg@...il.com>:
> 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.

Ping: Does anyone has any comment on this series?
Sorry, last mail was HTML by accident.
