serial: mvebu-uart: initial support for Armada-3700 serial port

2016-03-08T00:11:14Z

Armada-3700's uart is a simple serial port, which doesn't support. Configuring the modem control lines. The uart port has a 32 bytes Tx FIFO and a 64 bytes Rx FIFO The uart driver implements the uart core operations. It also support the system (early) console based on Armada-3700's serial port. Known Issue: The uart driver currently doesn't support clock programming, which means the baud-rate stays with the default value configured by the bootloader at boot time [gregory.clement@free-electrons.com: Rewrite many part which are too long to enumerate] Signed-off-by: Wilson Ding Signed-off-by: Nadav Haklai Signed-off-by: Gregory CLEMENT Acked-by: Rob Herring Signed-off-by: Greg Kroah-Hartman

tty: ar933x_uart: move devicetree binding documentation

2013-09-26T19:33:49Z

Commit 'tty: ar933x_uart: add device tree support and binding documentation' introduced a new doc in bindins/tty/serial. According to a recent thread [1] on the linux-serial list, the binding documentation of serial drivers should be added into bindings/serial. Move the documentation of qca,ar9330-uart to the correct place. 1. http://marc.info/?l=linux-serial&m=137771295411517 Cc: devicetree@vger.kernel.org Signed-off-by: Gabor Juhos Signed-off-by: Greg Kroah-Hartman

tty: ar933x_uart: add device tree support and binding documentation

2013-08-30T21:11:27Z

Modify the probe routine to get the port line number from device tree if the 'of_node' is populated in the platform device. The driver can be built as module, thus add an OF specific module device table as well to support module auto loading. This makes it possible to use the driver for AR9330 UART devices specified in device tree. Cc: devicetree@vger.kernel.org Signed-off-by: Gabor Juhos Signed-off-by: Greg Kroah-Hartman

devicetree: serial: Document msm_serial bindings

2013-08-28T23:03:29Z

Let's fix up the msm serial device bindings so that it's clearer what hardware is supported. Instead of using hsuart (for high speed uart) let's use uartdm because that matches the actual name of the hardware. Also, let's add the version information in case we need to differentiate between different versions of the hardware in the future. Finally, lets specify that clocks are required (the clock bindings didn't exist when the original binding was written) and also specify dma bindings just in case we want to use it in software. We split the binding into two files to make it clearer what's required and not required. Cc: David Brown Cc: Acked-by: Kumar Gala Signed-off-by: Stephen Boyd Signed-off-by: Greg Kroah-Hartman

serial: unify serial bindings into a single dir

2013-08-28T23:02:48Z

Move all bindings in bindings/tty/serial into bindings/serial so we only have one place dir with serial/uart related bindings in it. Signed-off-by: Kumar Gala Signed-off-by: Greg Kroah-Hartman

serial: fsl-imx-uart: Cleanup duplicate device tree binding

2013-08-28T23:02:48Z

We had two bindings for the same serial device, it looks like the one in tty/serial/fsl-imx-uart.txt is the more up to date one so go with it and merge a few things about the use/need for aliases in from serial/fsl-imx-uart.txt. Signed-off-by: Kumar Gala Signed-off-by: Greg Kroah-Hartman

serial: mxs: enable the DMA only when the RTS/CTS is valid

2013-08-05T07:05:17Z

The original DMA support works only when RTS/CTS is enabled. (see the "e800163 serial: mxs-auart: add the DMA support for mx28") But after several patches, DMA support has lost this limit. (see the "bcc20f9 serial: mxs-auart: move to use generic DMA helper") So an UART without the RTS/CTS lines may also enables the DMA support, in which case the UART may gets unpredictable results. This patch adds an optional property for the UART DT node which indicates the UART has RTS and CTS lines, and it also means you enable the DMA support for this UART. This patch also adds a macro MXS_AUART_RTSCTS, and uses it to check RTS/CTS before we enable the DMA for the UART.
