2013-08-28serial: unify serial bindings into a single dirKumar Gala1-49/+0
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 <galak@codeaurora.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-25serial: of_serial: Handle auto-flow-control propertyHeikki Krogerus1-0/+3
Automatic Flow Control capability is not tied to this property. This is only one way of detecting it. The property is limited to be used only with 8250 driver.

2013-03-25serial: of_serial: Handle fifo-size propertyHeikki Krogerus1-0/+1
This will reduce the need for extra types in 8250.c just in case the fifo size differs from the standard. Signed-off-by: Heikki Krogerus <heikki.krogerus@linux.intel.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2013-03-12tty/serial: Add support for Altera serial portLey Foon Tan1-0/+3
Add support for Altera 8250/16550 compatible serial port. Signed-off-by: Ley Foon Tan <lftan@altera.com> Cc: stable <stable@vger.kernel.org> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2012-07-17tty: of_serial: add no-loopback-test propertyGabor Juhos1-0/+2
The loopback test mode is not implemented in all NS16550 compatible UARTs. The 8250 driver uses the UPF_SKIP_TEST flag to indicate this, however it is not possible to set this flag via device-tree. Add a new 'no-loopback-test' property, and modify the of_serial driver to set the UPF_SKIP_TEST flag if the property is present.

2012-06-12serial/of-serial: Add LPC3220 standard UART compatible stringRoland Stigge1-0/+1
This patch adds a "compatible" string for the new 8250 UART type PORT_LPC3220. This is necessary for initializing LPC32xx UARTs via DT. Signed-off-by: Roland Stigge <stigge@antcom.de> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>
2011-07-10tty/serial: Add devicetree support for nVidia Tegra serial portsGrant Likely1-1/+1

2011-06-30tty: of_serial: support for 32 bit accessesJamie Iles1-0/+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.

2011-06-27dt: document the of_serial bindingsJamie Iles1-0/+33
The of_serial bindings can be used to register a number of serial devices. Document this binding with all of the others. v3: remove device-type and clarify used-by-rtas Signed-off-by: Jamie Iles <jamie@jamieiles.com> Acked-by: Arnd Bergmann <arnd@arndb.de> Signed-off-by: Grant Likely <grant.likely@secretlab.ca>
