Rozycki" To: Greg Kroah-Hartman , Jiri Slaby cc: linux-serial@vger.kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH v2 0/2] serial: 8250: Fixes for Oxford Semiconductor 950 UARTs Message-ID: User-Agent: Alpine 2.21 (DEB 202 2017-01-01) MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Precedence: bulk List-ID: X-Mailing-List: linux-kernel@vger.kernel.org Hi, Here's v2 of the outstanding fixes for Oxford Semiconductor 950 UARTs, comprising an chip-specific clock handling implementation for accurate baud rate selection including higher baud rates and FIFO rx trigger level configuration. NB I have since had an opportunity to check what transceiver chips have been used with the option card I have been experimenting with, and they've turned out to be the Zywyn ZT3243F, specified for up to 1Mbps, so no surprise they eventually gave up as the rates I have tried increased, and quite interesting it was only at 4Mbps that they did it.
