* tty/serial: Add GPIOLIB helpers for controlling modem linesRichard Genoud2014-05-281-0/+3
| | | | | | | | | | | | This patch add some helpers to control modem lines (CTS/RTS/DSR...) via GPIO. This will be useful for many boards which have a serial controller that only handle CTS/RTS pins (or even just RX/TX).

* serial: sc16is7xxJon Ringle2014-04-251-0/+1
| | | | | | | | | | | | | The SC16IS7xx is a slave I2C-bus/SPI interface to a single-channel high performance UART. The SC16IS7xx's internal register set is backward-compatible with the widely used and widely popular 16C450. The SC16IS7xx also provides additional advanced features such as auto hardware and software flow control, automatic RS-485 support, and software reset.

| | | | | | | | | | | Add earlycon support for the arm/arm64 semihosting debug serial interface. This allows enabling a debug console when early_params are processed. This is based on the arm64 earlyprintk smh support and is intended to replace it.

* tty/serial: add generic serial earlyconRob Herring2014-04-241-0/+2
| | | | | | | | | | | | | | | This introduces generic earlycon infrastructure for serial devices based on the 8250 earlycon. This allows for supporting earlycon option with other serial devices. The earlycon output is enabled at the time early_params are processed. Only architectures that have fixmap support or have functional ioremap when early_params are processed are supported. This is the same restriction that the 8250 driver had. Signed-off-by: Rob Herring <robh@kernel.org> Cc: Jiri Slaby <jslaby@suse.cz> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

* tty/serial: Add kgdb_nmi driverAnton Vorontsov2012-09-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This special driver makes it possible to temporary use NMI debugger port as a normal console by issuing 'nmi_console' command (assuming that the port is attached to KGDB). Unlike KDB's disable_nmi command, with this driver you are always able to go back to the debugger using KGDB escape sequence ($3#33). This is because this console driver processes the input in NMI context, and thus is able to intercept the magic sequence. Note that since the console interprets input and uses polling communication methods, for things like PPP it is still better to fully detach debugger port from the KGDB NMI (i.e. disable_nmi), and use raw console. Usually, to enter the debugger one have to type the magic sequence, so initially the kernel will print the following prompt on the NMI debugger console: Type $3#33 to enter the debugger> For convenience, there is a kgdb_fiq.knock kernel command line option, when set to 0, this turns the special command to just a return key press, so the kernel will be printing this: Hit <return> to enter the debugger> This is more convenient for long debugging sessions, although it makes nmi_console feature somewhat useless. And for the cases when NMI connected to a dedicated button, the knocking can be disabled altogether by setting kgdb_fiq.knock to -1.

* | serial: add irq handler for Freescale 16550 errata.Paul Gortmaker2011-12-091-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Sending a break on the SOC UARTs found in some MPC83xx/85xx/86xx chips seems to cause a short lived IRQ storm (/proc/interrupts typically shows somewhere between 300 and 1500 events). Unfortunately this renders SysRQ over the serial console completely inoperable. The suggested workaround in the errata is to read the Rx register, wait one character period, and then read the Rx register again. We achieve this by tracking the old LSR value, and on the subsequent interrupt event after a break, we don't read LSR, instead we just read the RBR again and return immediately. The "fsl,ns16550" is used in the compatible field of the serial device to mark UARTs known to have this issue. Thanks to Scott Wood for providing the errata data which led to a much cleaner fix.

| | | | | | | | | | | | | | | | | | The Xilinx PS Uart is used on the new ARM based SoC. This UART is not compatible with others such that a seperate driver is required. Signed-off-by: John Linn <john.linn@xilinx.com> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>

As such, it is a maintainence burden with no benefit. This gets rid of two defconfigs. Signed-off-by: Russell King <rmk+kernel@arm.linux.org.uk>
* | serial: msm_serial_hs: Add MSM high speed UART driverMayank Rana2011-03-071-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This driver supports UART-DM HW on MSM platforms. It uses the on chip DMA to drive data transfers and has optional support for UART power management independent of Linux suspend/resume and wakeup from Rx. The driver was originally developed by Google. It is functionally equivalent to the version available at: http://android.git.kernel.org/?p=kernel/experimental.git the differences being: 1) Remove wakelocks and change unsupported DMA API. 2) Replace clock selection register codes by macros. 3) Fix checkpatch errors and add inline documentation. 4) Add runtime PM hooks for active power state transitions. 5) Handle error path and cleanup resources if required.

* tty: move drivers/serial/ to drivers/tty/serial/Greg Kroah-Hartman2011-01-131-0/+94
The serial drivers are really just tty drivers, so move them to drivers/tty/ to make things a bit neater overall. This is part of the tty/serial driver movement proceedure as proposed by Arnd Bergmann and approved by everyone involved a number of months ago.
