* serial: mvebu-uart: initial support for Armada-3700 serial portWilson Ding2016-03-071-0/+13
| | | | | | | | | | | | | | | | | | | | | | | | 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 <dingwei@marvell.com> Signed-off-by: Nadav Haklai <nadavh@marvell.com> Signed-off-by: Gregory CLEMENT <gregory.clement@free-electrons.com> Acked-by: Rob Herring <robh@kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
* tty: ar933x_uart: move devicetree binding documentationGabor Juhos2013-09-261-34/+0
| | | | | | | | | | | | | | | | | | | 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 <juhosg@openwrt.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

| | | | | | | | | | | | | | | 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.

* devicetree: serial: Document msm_serial bindingsStephen Boyd2013-08-281-27/+0
| | | | | | | | | | | | | | | | | | | 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.

* serial: mxs: enable the DMA only when the RTS/CTS is validHuang Shijie2013-08-051-0/+4
| | | | | | | | | | | | | | | | | | | | | | 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.

* tty: of_serial: support for 32 bit accessesJamie Iles2011-06-301-0/+3
| | | | | | | | | | | Some platforms e.g. TI Davinci require 32-bit accesses to the UARTs. The of_serial driver currently registers all UARTs as UPIO_MEM. Add a new attribute "reg-io-width" to allow the port to be registered with different IO width requirements.
